What’s On My Mind: 5 Examples of AI Transformation

My friend Mark Schaefer recently wrote on LinkedIn:

---

I have a sinking feeling of being left behind.

I’m reading about big companies and their AI re-invention and startups being “AI first.” But here I am as a small business, fully immersed in the smart ideas of AI and using GPT as my sidekick every hour of the day. Yet the foundation of my business is Word, Excel, PowerPoint, and a WordPress blog/website. This is CRUDE.

AI is creating iterative improvements but I am not TRANSFORMING. I am augmenting, not reimagining. I sense that as a small business, I don’t have the ability to really LEAD with AI except to maybe be a little better at prompts than the next guy. Thoughts?

---

We’ve talked over the past few newsletter issues about the difference between optimization and transformation…

• Part 1
• Part 2
• Part 3
• Part 4

… and that’s exactly what Mark is hitting on. He’s optimizing. He’s not transforming, not changing forms, not doing completely different things than he’s always done.

And he’s not alone. I’ve been on the road for a month now, talking to audiences near and far about generative AI and its wild capabilities. Almost everyone has the same kinds of questions, the same kinds of fears Mark has, the same doubts. At Content Jam last week, I sat down with agency owners and told them that if their business model has been based on generating corporate slop (“who wants more executive thought leadership?”), their businesses are toast. Generative AI can generate corporate slop better than you can, faster than you can, cheaper than you can.

Generative AI as Mark describes it, as he’s said he’s using it, optimizes for bigger, better, faster, cheaper. Optimization takes what’s there and makes it better.

But as the quote goes, doing the same thing and expecting different results is the definition of insanity.

And even that is up for grabs. We used to glibly quote that if you do what you’ve always done, you’ll get what you’ve always gotten. Except that’s not even true any more, because AI can also do that bigger, better, faster, and cheaper than you.

Optimizing yesterday’s way of doing things will not get you to today. It certainly will not get you to tomorrow.

So today, let’s tackle the very pointed question Mark asked: does a small business have the ability to lead with AI beyond being better at prompts?

Oh yes. Yes indeed. But it requires actual transformation. Let’s look at five examples of how any small business – because Trust Insights, for example, is a small business that leads with AI – can change how it thinks and approaches the world with AI.

Part 1: The Five Ps

Katie Robbert, my amazing business partner and CEO, pioneered the Trust Insights 5P Framework for situations exactly like this. The 5Ps are all about figuring out what you want to do.

• Purpose – What is the question we’re trying to answer? What is the problem we’re trying to solve?
• People – Who should you involve? Who needs to know about this?
• Process – How will we answer this question, solve this problem? What are the specific methods, processes, techniques, and tactics involved?
• Platform – What tools will we use, digital and analog?
• Performance – How will we measure success? How do we know we solved the problem? How do we quantify success?

When it comes to generative AI and transformation, leading with the technology – AI – is the wrong way to do it. Leading with purpose, understanding performance and the outcomes we want to create – will get us where need to go. Before you do anything with AI, you must understand this and have a clear vision in your head about your purpose and performance.

The goal is to lead. The outcome is to be seen as a leader by your peers and audience. Those are clear. The question then becomes how – how do you lead?

What does AI fundamentally do that is different than almost every other technology? What is special about AI?

The optimist would say that it democratizes skill. AI gives you the ability to generate things not only bigger, better, faster, and cheaper, but also different. AI can create music. I can’t create music. AI can paint in almost any style. I can’t even paint the walls of my house well.

The pessimist would say that it devalues skill. That’s equally true, and something we shouldn’t forget. When you can create images that are as stunning as a professional photographer, it brings the valid question to mind of what the photographer’s skills are worth.

But that angle, positive or negative, remains true. AI gives you access to skills you don’t have. That’s the basis for transformation – your ideas now have new avenues and outlets available to them. If you can think it, if you can explain it, you can now create it.

Part 2: Transforming Business Processes

One of the reasons folks like Mark feel stuck is that you’re hitting the limits of what a generative AI engine can do by itself. There’s only so much you can do with ChatGPT by itself, in the same way that there’s only so much you can do with a car engine by itself. A car engine is important, there’s no debate about that. A car without an engine is a lawn decoration at best.

But an engine isn’t enough. You need the rest of the car – you need to put the engine in something. That’s where tools like n8n, Make, Zapier, and the gazillion other automation tools come in. They allow you to connect the rest of your processes to AI. Onec you’ve got working prompts, once you’ve mastered the basics of prompting generative AI, then you can start scaling it. You can start thinking about ways to apply it that go far beyond the prompt itself.

Look at the palette of tools available inside a system like n8n. That’s a great place to spark your imagination. You see connectors for things like WordPress, YouTube, Google Drive, and AirTable, and your mind should start asking questions like, “How could I connect my WordPress site to my YouTube channel? What things could I do that I couldn’t do before?”

What would it look like to connect your CRM to a generative AI model and do qualitative lead scoring? Not lead scores based on simple things like BANT criteria, but on the actual language people use to communicate with you? That’s transformative. It’s not doing what you’ve always done. It’s doing something different and maybe better.

Part 3: Transforming Media

Generative AI, as I mentioned, gives you access to skills you don’t have. I have exactly zero musical abilities. None. Not a musical bone in my body. Yet I can take any piece of content, put it through generative AI, and turn that content into media of all different kinds.

What we have to keep in mind is that our creations need to start as something we understand, something that we can feel. If we understand our idea, if we understand our starting point and the emotions we feel, we can guide AI to generate new media based on that. If we don’t understand the beating heart of our creations, then AI will simply generate slop.

Here’s an example. This is a photo I shot at dinner with Andy Crestodina, Brian Massey, Nancy Harhut, and Jessica Best, the speakers at Content Jam this past week. Also pictures are Amanda Gant, Rich Brooks, Izzy Siedman, and Arnold whose last name escapes me.

I remember the feeling of this conversation. I remember what we talked about, what we were laughing about at this very minute. If I take the photo, take the memories, take the feelings, and put all of it into a multimodal AI model, I can create the necessary ingredients for AI to render it as a song:

That’s not something I could do myself. Not even close. It’s a literal transformation, from one medium to the next, a photo turned into a song. And we don’t have to stop there. We could take the exact same background information and context to turn it into an abstract painting:

That’s far beyond my skills. Does it convey the mood and feeling I had at dinner? Yes, it really does, that warm, inclusive sense inside the circle of trust, with the rest of the world outside.

AI tools exist today to transform our ideas from one medium to the next flawlessly. We just have to provide the starting point – the feelings, the emotions, the ideas. If you can dream it, you can have AI bring it to life.

Part 4: Transforming Software

We’ve joked for 20 years now that “there’s an app for that”… but just because there’s an app for it doesn’t mean the app is any good. What if the apps that exist are insufficient for our particular needs? What if there are privacy issues? What if there’s that one feature we wish apps had that simply doesn’t exist?

At Google Cloud Next, Google announced Firebase Studio, an end-to-end app development environment using Firebase and Gemini, that allows you to create mobile apps with prompts. Anything you can think of, any frustration you’ve ever had with existing apps… just prompt a new one.

You don’t need to be a coder to try it out and have a conversation about the app. You can talk it through with the AI and have it create the entire app, soup to nuts, and then deploy it. Of course, tied into the Firebase system, it’s dependent on Google infrastructure, but you can see very quickly exactly where this technology is going.

Transformation is about taking the ideas you could never do and doing them. What does life look like when, with your ideas and your words, you can start to build everything you’ve ever wanted (at least in software).

Maybe you’ve got a mobile game you’ve always wanted to play.

Maybe you’ve got an expense reporting process that no app on the market works well with.

Maybe you’ve got an idea for an AI cake baking assistant.

Whatever your idea is, bring it to life with AI.

Part 5: Transforming Physicality

The final angle here is about interfacing with the real world itself. AI lives inside the black mirror, yes. At its heart, it is just more software. But what it enables us to do is interface not only with other digital parts of the world, but with the world as a whole.

Here’s a simple example. I was testing out the realtime video streaming in AI Studio on my iPad.

My furnace had a leaky part, and I wasn’t sure if I needed a plumber or not – it was only a tiny drop of water every now and again. With AI Studio, I hovered my iPad over the furnace manuals so it understood what it was looking at, then pointed to the leaky part and asked the AI model why it was leaking.

Silly as it may be, the AI told me I just needed to tighten the valve with my fingers. Problem solved.

Imagine generative AI as your companion throughout your life, watching you as you work, offering suggestions and advice when you want it, when you need it. For example, when I’m running into trouble doing something in complicated software like Adobe Premiere, I’ll turn on AI Studio, share my screen, explain what I’m trying to do, and it will often tell me exactly how to do it, like a tutor on demand.

Beyond that, there are ways to tie generative AI models into real world systems, through Model Context Protocol, or MCP. You know all those action figure images people are sharing all over social media, where generative AI takes an image of you and turns you into an action figure package?

What if you could have it for real, in the real world? Seems far fetched, but there’s an MCP server that interfaces with Blender, the 3D software. Connect your generative AI output to Blender, have generative AI create the necessary 3D files, and then send those to a 3D printer for printing. Suddenly your whimsical action figure image is the real deal.

Part 6: Wrapping Up

To revisit Mark’s original post, his sinking feeling about falling behind is both justified and correct. He is right. If you’re using AI to do what you’ve always done, you’re not transforming, you’re optimizing.

And optimizing for a faster horse when someone else has a car is not a winning strategy.

Transformation comes from leaving behind the way you’ve always done it. As Katie says, new technology doesn’t solve old problems. Think clearly about your purpose and the outcomes you want to create – happy, loyal customers, for example – and then start thinking about how you can take the essence of who you are, what you do, and how you think and apply it to the many different ways AI can enable you to do things better.

The essence of who you are doesn’t change in an AI world. The way you express it does.

Imagine showing up at a sales pitch with a giclée painting of an abstract piece of art that encompasses your RFP response. If the buying committee you’re pitching happens to like that kind of art, you’ve just made an impression no one else would even dream of making, because they’re optimizing for yesterday and not transforming for tomorrow.

That’s transformation, and that’s how to eliminate that feeling of falling behind. You focus less on the tools and more on what new, different, and transformative outcomes you can create with the tools.

What’s On My Mind: How To Get Started with Local AI Models

After a post ran wild on LinkedIn, I suppose it’s time to write up how to get started with local AI models. I’ll provide two cautions on this issue of the newsletter. First, it will inherently be more technical than you’re probably used to with generative AI. You and I are used to opening a browser window, logging into the AI tools of our choice, and getting things done. We never have to think about the plumbing and infrastructure that makes those tools possible.

If you’re uncomfortable or unable (due to company IT policies, for example) to do this more technical stuff, then feel free to just relax and read, or skip this issue entirely.

The second caution is about language. There are a lot of confusing terms in this space, so we should do a bit of definition setting. I use several different terms that are somewhat interchangeable, so let’s set the table:

• Local AI: generative AI models that you run on your hardware, from your phone to your own on-premise datacenters. Any environment where you have complete control of the machine that the AI model is running on is local AI.
• Open model/open weights model: generative AI models which are distributed for free online by model makers. These models enable you to run them anywhere, and you don’t have to pay the model maker to make use of it. Some people will mistakenly call this open source models or open source AI, but almost no model makers distribute the training data set itself that would be needed to qualify as truly open source.

These are technically NOT the same thing. Local AI is local to you and your network. Open models can run anywhere. For example, you can run open models in IBM WatsonX.ai, IBM’s generative AI secure cloud. It’s not at all local. You have no control over the machine it’s running on. But for many organizations, especially those running inside IBM’s cloud and needing IBM’s governance technology, it’s a great place to run open weights models.

We should probably talk about WHY you’d want to do this, when services like ChatGPT are so convenient. There are five reasons you might want to use a local AI models over a SaaS AI service:

• Privacy: when you run models on your hardware locally, no data ever leaves your system. You have as much privacy and security as your machine itself. This is a HUGE draw for anyone working with sensitive data.
• Cost: when you run models on your hardware locally, the cost is your operating cost (usually electricity). This is super important for things like R&D where you might be making tons of API calls to a model as part of your development process. Using a cloud provider, this could rack up huge bills before you even have a product to show or sell. Using local models reduces that cost substantially – and might be successful enough that you could justify using a local model even in production.
• Sustainability: the less power you use to operate AI, the more sustainable it is. Yes, there are clearly economies of scale when providers have massive, concentrated compute power, but given that they’re all looking to vacuum up as much electricity as possible, it’s not a terrible stretch of the imagination to realize AI is incredibly resource hungry. Using local models can reduce that power consumption if done well.
• Control: when you run models locally, you have complete control over how they’re configured, far more than any cloud service would let you. This is a double edged sword; you can misconfigure a model to the point where it becomes nonfunctional – but if there are specific things you want a model to do, access to those extra controls can be helpful.
• Reliability: local AI models run on your machine. Once you download them, they’re yours. If OpenAI closed up shop tomorrow, ChatGPT would be gone, but your local AI would continue to function for as long as your computer did.

With these points in mind, let’s dig into the process of HOW to set these things up. If you’re watching the video version of this newsletter, you’ll see some of these examples in greater detail. We need to talk through hardware, models, software, configuration, and use, in that order.

Part 1: Hardware

To run generative AI models on your machine, you need sufficient resources. Generative AI models typically need lots and lots of memory to run well. Your computer has two kinds of memory that are important – regular computer memory (RAM), and graphics memory (VRAM, or video RAM). For generative AI to run well, VRAM is the most important – and the wildest variable.

Today’s gaming PC laptops typically come with 12-16 GB of VRAM, though some high end gaming rigs come with more. Today’s Macs are a different beast – Macs since 2019 (the M-series Macs with names like M1, M2, M3, M4) have shared memory, which means that regular RAM and VRAM are the same thing. There’s a big pool that the computer automatically shares.

This matters a lot because on PCs, you will often need software that can load AI models on both your VRAM and RAM, and when an AI models is running on regular RAM, it is s-l-o-w.

The basic message here is simple: if you’re buying/using PCs, get as much VRAM as you can afford. If you’re buying/using Macs, get as much memory as you can afford. More is always better.

Your computer, somewhere in its settings (it’s been a hot minute since I’ve used a PC but I’d guess either Task Manager or System Preferences will get you where you want to go, and you can probably ask Windows Copilot to just tell you) will tell you how much memory you have to work with. If I remember correctly, both Macs and PCs have an Activity Manager app that tells you the current state of your computer.

Find your memory status, close all your open applications, and make note of how much of each kind of memory you have.

For example, on my MacBook, this is what I see with nothing else running:

You can see that I have about 110 GB of total memory available. We’ll need this information shortly.

Part 2: Models

Once we’ve figured out how much memory is available to us overall, we can start ‘shopping’ for models. I say shopping because we need to find open weights models that suit our needs. On the model repository Hugging Face, there are over 1.6 million different models to pick from. Granted, many of them are purpose built for specific tasks, so we’ll focus on a few big families of models which are currently high-performing.

The three families I recommend for the average business user are:

• Google Gemma
• Meta Llama
• Mistral

In each family, there are different models sizes. You’ll see this listed in the model name, the number of parameters that the model contains. Parameters are how much knowledge and information a model contains. For example, you’ll see things like Google Gemma 3 1B, 4B, 12B, 27B, etc. Those numbers indicate 1 billion parameters, 4 billion parameters, etc.

Generally speaking, more is better BUT there’s a limitation: the bigger a model is in parameters, the more memory it needs to run well. If you pick a model that’s bigger than the memory you have available, it will literally crash your computer by consuming all the memory and grinding your entire computer to a halt.

The tradeoff with smaller parameter models? Parameters are knowledge. The fewer the parameters, the dumber the model is. A model like Google Gemma 1B is coherent but will hallucinate just about everything, making things up because it has almost no background knowledge. A model like Google Gemma 27B is going to be far more fluent and knowledgeable.

It’s important to say that open models in general that you can run on a laptop are going to be far less knowledgeable than the big frontier models we’re used to. ChatGPT’s GPT-4o model is estimated to have trillions of parameters, as is Google Gemini. We’ll talk more about the implications of this in a little while.

Before we dig into choosing specific models, we need to talk about a very confusing aspect of selecting a model: quantization.

Model makers release their models in the highest possible accuracy format. When we interact with those versions of the models, they perform tasks at their highest accuracy level – but they are memory hogs. They eat up memory like crazy and run fairly slowly.

The open weights community will often take a model made by a model maker and perform quantization on it, which is a kind of compression. What it does is it reduces the accuracy of the model, but makes it significantly faster to operate. We can dig into the math of quantization another time, but the cheat sheet version is that we want models that are quantized at 4, 5, or 6 bits. Generally speaking, quantization is a tradeoff between resource usage and accuracy, and 4-6 bit quantization is the sweet spot for most models.

You see this in model names, like gemma-3-27b-q5_k_l. This rather arcane name means Gemma 3 the model, 27 billion parameter version, and 5 bit quantization.

Here’s the fastest cheat sheet I can offer on quantization: in general, use either q4 or q5 models whenever you can.

Then choose a model based on its parameters and your memory. My rule of thumb is: take the number of parameters, double it, and that’s the RAM you‘ll need to have for the model to be useful. I define useful as a model that operates at a reasonable speed (15 tokens/second or so) and has a large enough context window (64K or so) to be useful for most common tasks.

For example, suppose you chose Google Gemma 3 4B, at a q4 or q5 quantization. 4 * 2 = 8, so you’ll need 8 GB of VRAM available to run it well. (Yes, for the more technical folks, there are a ton of nuances here, but we’re trying to get started. Doubling the memory like this accounts for a generous context window and the key/value cache.)

So from part 1, what’s your available VRAM? If you have a 16 GB graphics card, you can safely run an 8B model well, or anything below that number. You could run Google Gemma 3 4B easily. Yes, technically you can run Google Gemma 3 12B, but it’s going to be so slow and with such a small context window (the available short term memory in a chat) that it’s not going to be useful.

On my Mac, I have about 110 GB of memory available, which means I can run any size Gemma model up to its max size of 27B and have it be usable and fast. I could run models up to 55 billion parameters on my current setup.

When we hit up the Hugging Face repository for models, or look at the model catalogs in interfaces, this now gives us a baseline for choosing models.

We can look at the models by family and parameters without also having to take quantization into account beyond the basics, at least for getting started.

Let’s move onto software.

Part 3: Software

Now that we’ve got an understanding of what models we can run, we need to get the necessary software to run them. No one runs an AI model directly; AI models are essentially just gigantic databases of statistics at their core. To make use of a model, we need an interface around it. This is akin to cars; no one drives down the road sitting on an engine block. The engine block is embedded in the car itself, and while the engine block is critical – a car can’t go anywhere without an engine – neither is the engine useful without the car.

For the average person who wants to get started with local AI models, you’ll want to choose an interface that also has the back end server built into it. Think about AI interfaces like you think about the Web, with two major parts, a server and a client.

When you surf the web, your client – the web browser, like Safari or Chrome or Brave – goes out and interfaces with someone else’s web server that contains the web site. Companies like WP Engine have servers – lots of them, big hardware – that serve up software like WordPress and ultimately websites like the Trust Insights website. You need both – a client without a server is useless, and vice versa.

AI models work somewhat similarly. There’s a server that serves up the model, and a client that interfaces with it. When you visit ChatGPT or Claude or Gemini by browser or app, you’re using the client to talk to the AI servers that are running at those big tech companies.

In the local AI model space, there are software packages that bundle both together, that are both client and server. This is what we want to use for getting started with local AI at the most basic level.

There are two software packages I recommend for the average person who’s not super eager to set up servers: AnythingLLM and LM Studio. Both of these are free; the main differences are in functionality. AnythingLLM has a LOT of stuff baked in, like document management, speech recognition, etc. It tries to do a lot and for the most part it succeeds; it also has the basic chat style interface we all know and use.

LM Studio provides the same familiar chat interface as well, but tries to be a more robust server as well as a client. It’s especially good for current M-series Macs as it supports Apple’s MLX AI standard. An MLX version of a model runs 5-8% faster than a non-MLX model.

How do you decide between the two? If you plan on using agents, APIs, or developing code against your local AI, I strongly suggest LM Studio (Or if you have a Mac). If you plan on just using it as an end user consumer, the way you use ChatGPT or Gemini today, then AnythingLLM would be a good choice.

These are standard apps that run on your computer, so install them like you’d install any other piece of software.

Part 4: Configuration

Just as a piece of newly installed software like Microsoft Word needs some configuration or tailoring to make it useful to your specific use case, so too does AI software need some configuration to make it useful.

We first have to decide which model to use. There are a ton of choices. One of the peculiarities of open models is that with so many of them, different models are known to be good at different tasks, and there are a lot of specialized models that are purpose built or tuned for one kind of task. This is a contrast to a tool like Gemini, Claude, or ChatGPT that try and largely succeed at being good at many different kinds of tasks.

Let’s look at a few different model families and what they’re good at.

• Google Gemma 3: Gemma 3 does a very good job of following instructions, especially the 12B and 27B versions. If you have tasks where instruction following (like step by step instructions, workflows, etc.) are important, Gemma 3 will serve you well. Gemma can write but tends to be a bit terse.
• Meta Llama 3.3: While Llama 4 is in market, it’s too large for most consumer hardware. Llama 3.3 is the current version that can run on consumer hardware. Llama 3.3 is a decent fit for nonfiction writing.
• Mistral Small: The Mistral family excels at multilingual work and writing. It’s very capable, especially the current Small version, Small 3 24B, a 24 billion parameters model. Remember you’ll want to have 48 GB of VRAM/memory to get solid use out of it.
• DeepCoder: If you’re using generative AI specifically to write code, DeepCoder is a fantastic model for coding, especially first drafts.

Once you choose a model that is an appropriate size for the memory and resources you have, download it in the app’s interface.

In the main chat window or in the settings, depending on what app you’re using, you’ll want to take a few moments to get acclimated to features as well as possibly mess with some settings. One of the more useful settings to know is a parameter called temperature. You’ll see this in the model settings.

What does temperature do? Fundamentally, temperature controls the level of randomness in the model’s responses. A low temperature means less randomness. A higher temperature means more randomness.

Why would you want to mess with this? Some tasks are very deterministic; you don’t want the model getting too creative. For example, if you asked a model to classify some text in a set of defined categories, you would set a low temperature, like 0.5, to keep it from arbitrarily coming up with new categories.

Other tasks are more probabilistic, like creative writing. Set the temperature too low, and you get incredibly robotic generation. A temperature anywhere from 0.7 to 1.0 will tend to yield more creative writing by allowing the model more freedom to be creative.

For those folks used to an interface like ChatGPT, this might seem unusual. Behind the scenes, services like ChatGPT have the exact same settings and controls; it’s just that those end user models are usually set by the provider and the average consumer has no ability to control them or change them.

Okay, so you’ve got your software installed. You’ve got your model downloaded and installed. You’ve got your settings configured. You’re finally ready to begin using local AI.

Part 5: Usage

Finally, we get to the good part, right? Well, the good part is surprisingly dull: it’s just like every other generative AI large language model you’ve used. There are a couple of twists that are important to know when it comes to open models and local AI.

Remember how we talked about parameter counts, how the more parameters a model has, the better it tends to perform? This is relevant both for instruction following (aka doing what you tell it to do in your prompts) as well as knowledge. More parameters means more encoded knowledge.

But except for really, really big models like Llama 3.1 405B (405 billion parameters), DeepSeek (671 billion parameters), and a handful of others, most local models are going to be effectively under 50 billion parameters. At that scale, models will have some knowledge, but the risks of hallucination are very high.

What that means is that you have to bring more data to the party. Here’s a simple example. If you ask a small model like Gemma 3 4B who the CEO of Trust Insights is, it’ll give a non-sensical answer. If you provide the answer, it’ll recite it perfectly.

Now, you might say (quite correctly) that if we have to provide the answer, what’s the point? Well, now we get into the use cases of generative AI (which you can learn more about in my new course, Generative AI Use Cases for Marketers) and what smaller models are good at.

• Extraction: take data out of other data
• Classification: organize data
• Summarization: make big data into small data
• Rewriting: transform data from one form to another
• Synthesis: take small data and aggregate it into big data
• Question Answering: answer questions about your data or in general
• Generation: make new data

When it comes to local AI, the first 5 use cases here are where it really shines. Given the data, even very small models like Gemma 3 4B can do a very capable job – and they’ll be lightning quick about it as well.

Where they will fall down is on use cases 6 and 7, when we’re asking the models to create new data. For example, asking Gemma 3 for a restaurant recommendation in your area without providing any data is not going to go well. It just doesn’t have enough knowledge. Ask it while providing it a large JSON document of restaurants and their offerings, and it’ll do just fine.

The same is true of generation. Ask it to write, for example, a blog post about B2B marketing without any background data and it’s going to come up with generic slop. There’s just not enough knowledge in any one domain for it to create really unique, compelling content, especially once you’re below about 10 billion parameters. Give it your backlog of newsletters and podcasts as a data store, and chances are it’ll do much better at generating something.

Where these models shine is on repetitive tasks, especially if you can automate them. Remember last week’s newsletter about n8n? A local AI model is going to be a huge cost saver if you can wire a workflow to use it rather than a cloud based service.

Part 6: Wrapping Up

We looked mostly at the how in this issue of the newsletter, and if you have the hardware and tools like LM Studio or AnythingLLM, you’re well positioned to start making use of local AI models.

One final caution on local AI, especially on laptops: using the GPU at full tilt consumes 100% of the energy of the system. Expect your fans to run, and you might even run down the battery – while your laptop is plugged in! All generative AI is incredibly power intensive, so if you’re using generative AI models heavily on your machine, don’t expect your machine to do many other things at the same time unless you’ve got a beast of a machine.

Remember the key reasons to use local models: cost, privacy, flexibility, sustainability, and reliability. State of the art performance is NOT one of the reasons to use them, so if you’re tackling a very complex task that demands state of the art performance, use a big frontier model instead.

I hope this guide gives you a great starting place for generative AI running locally. If you’d like a more strategic tour, watch this talk I gave at the MAICON 2024 conference on open models and local AI. Though there have been a lot of technical and tactical changes, the strategy remains largely the same.

我思我见：如何开始使用本地AI模型

在 LinkedIn 上的一篇帖子疯传之后，我想是时候写一篇关于如何开始使用本地AI模型的文章了。在本期时事通讯中，我将对此问题提出两个注意事项。首先，它本质上会比您可能习惯的生成式AI更具技术性。您和我习惯于打开浏览器窗口，登录我们选择的AI工具，然后完成工作。我们从不必考虑使这些工具成为可能的底层架构和基础设施。

如果您对这些更具技术性的操作感到不适或无法执行（例如，由于公司IT政策），那么请放松阅读，或者完全跳过本期内容。

第二个注意事项是关于术语。这个领域有很多令人困惑的术语，所以我们应该先做一些定义设定。我使用了几个有些可以互换的术语，所以让我们先明确一下：

• 本地AI (Local AI)：您在自己的硬件上运行的生成式AI模型，可以是从您的手机到您自己的本地数据中心。任何您完全控制运行AI模型的机器的环境都属于本地AI。
• 开放模型/开放权重模型 (Open model/open weights model)：由模型制作者免费在线分发的生成式AI模型。这些模型使您可以在任何地方运行它们，并且您无需向模型制作者付费即可使用。有些人会错误地称之为开源模型或开源AI，但几乎没有模型制作者会分发需要符合真正开源标准的训练数据集本身。

严格来说，这两者并不相同。本地AI是指对您和您的网络而言是本地的。开放模型可以在任何地方运行。例如，您可以在 IBM WatsonX.ai（IBM 的生成式AI安全云） 中运行开放模型。这完全不是本地的。您无法控制运行它的机器。但对于许多组织，特别是那些在IBM云内运行并需要IBM治理技术的组织来说，这是一个运行开放权重模型的好地方。

我们或许应该谈谈，当像 ChatGPT 这样的服务如此便捷时，您为什么还要想做这件事。您可能希望使用本地AI模型而不是SaaS AI服务的原因有五个：

• 隐私性 (Privacy)：当您在本地硬件上运行模型时，任何数据都不会离开您的系统。您的隐私和安全级别与您机器本身的安全级别相同。这对于任何处理敏感数据的人来说都具有巨大的吸引力。
• 成本 (Cost)：当您在本地硬件上运行模型时，成本就是您的运营成本（通常是电费）。这对于像研发这样的场景非常重要，因为在开发过程中，您可能会对模型进行大量的 API 调用。使用云提供商，这可能会在您甚至还没有产品展示或销售之前就产生巨额账单。使用本地模型可以大幅降低该成本——并且可能足够成功，以至于您可以证明即使在生产环境中使用本地模型也是合理的。
• 可持续性 (Sustainability)：您操作AI所用的电力越少，它就越可持续。是的，当提供商拥有大规模、集中的计算能力时，显然存在规模经济效应，但考虑到它们都在寻求尽可能多地消耗电力，不难想象AI是极其消耗资源的。如果做得好，使用本地模型可以减少这种功耗。
• 控制权 (Control)：当您在本地运行模型时，您对它们的配置方式拥有完全的控制权，远超任何云服务所允许的程度。这是一把双刃剑；您可能会错误配置模型以至于使其无法工作——但如果您希望模型执行特定任务，能够访问那些额外的控制选项会很有帮助。
• 可靠性 (Reliability)：本地AI模型在您的机器上运行。一旦您下载了它们，它们就属于您了。如果 OpenAI 明天关门大吉，ChatGPT 将会消失，但只要您的计算机还在运行，您的本地AI将继续工作。

考虑到这些要点，让我们深入探讨如何设置这些东西的过程。如果您正在观看本期时事通讯的视频版本，您将更详细地看到其中一些示例。我们需要按顺序讨论硬件、模型、软件、配置和使用。

第 1 部分：硬件 (Hardware)

要在您的机器上运行生成式AI模型，您需要足够的资源。生成式AI模型通常需要大量的内存才能良好运行。您的计算机有两种重要的内存——常规计算机内存（RAM）和图形内存（VRAM，或显存）。对于生成式AI的良好运行，VRAM 是最重要的——也是最大的变数。

如今的游戏笔记本电脑通常配备 12-16 GB 的 VRAM，尽管一些高端游戏设备配备更多。如今的 Mac 则不同——自 2019 年以来的 Mac（M 系列 Mac，名称如 M1、M2、M3、M4）具有共享内存，这意味着常规 RAM 和 VRAM 是同一回事。计算机自动共享一个大内存池。

这一点非常重要，因为在 PC 上，您通常需要能够将 AI 模型加载到 VRAM 和 RAM 上的软件，而当 AI 模型在常规 RAM 上运行时，速度会非常慢（s-l-o-w）。

这里的基本信息很简单：如果您购买/使用 PC，请购买您能负担得起的最大 VRAM。如果您购买/使用 Mac，请购买您能负担得起的最大内存。越多越好。

您的计算机，在其设置的某个地方（我已有一段时间没用过 PC 了，但我猜任务管理器或系统偏好设置可以带您找到目标，您或许可以直接问 Windows Copilot 来告诉您）会告诉您有多少可用内存。如果我没记错的话，Mac 和 PC 都有一个活动监视器应用程序，可以告诉您计算机的当前状态。

找到您的内存状态，关闭所有打开的应用程序，并记下您拥有的每种内存的大小。

例如，在我的 MacBook 上，这是我在没有运行其他程序时看到的情况：

您可以看到我大约有 110 GB 的总可用内存。我们很快会需要这些信息。

第 2 部分：模型 (Models)

一旦我们弄清楚了我们总共有多少可用内存，我们就可以开始“选购”模型了。我说选购是因为我们需要找到适合我们需求的开放权重模型。在模型存储库 Hugging Face 上，有超过 160 万种不同的模型可供选择。当然，其中许多是为特定任务量身定制的，所以我们将重点关注几个目前表现优异的大型模型家族。

我推荐给普通商业用户的三个模型家族是：

• Google Gemma
• Meta Llama
• Mistral

在每个家族中，都有不同的模型大小。您会在模型名称中看到这一点，即模型包含的参数数量。参数代表模型包含的知识和信息的多少。例如，您会看到像 Google Gemma 3 1B、4B、12B、27B 等。这些数字表示 10 亿参数、40 亿参数等。

一般来说，越多越好，但是有一个限制：模型的参数越大，它良好运行所需的内存就越多。如果您选择的模型大于您可用的内存，它会耗尽所有内存并使您的整个计算机陷入停顿，从而导致计算机崩溃。

较小参数模型的权衡是什么？参数即知识。参数越少，模型就越“笨”。像 Google Gemma 1B 这样的模型是连贯的，但几乎会对所有事情产生幻觉，因为它几乎没有背景知识，会凭空捏造。像 Google Gemma 27B 这样的模型将更加流畅和知识渊博。

需要强调的是，通常您可以在笔记本电脑上运行的开放模型，其知识渊博程度远不如我们习惯的大型前沿模型。据估计，ChatGPT 的 GPT-4o 模型拥有数万亿参数，Google Gemini 也是如此。我们稍后会详细讨论这意味着什么。

在我们深入选择特定模型之前，我们需要谈谈选择模型时一个非常令人困惑的方面：量化 (quantization)。

模型制作者以尽可能高的精度格式发布他们的模型。当我们与这些版本的模型交互时，它们以最高的准确度水平执行任务——但它们非常消耗内存。它们疯狂地占用内存并且运行相当缓慢。

开放权重社区通常会获取模型制作者制作的模型并对其进行量化，这是一种压缩方式。它的作用是降低模型的准确性，但使其运行速度显著加快。我们可以下次再深入探讨量化的数学原理，但速查表的版本是，我们想要量化为 4、5 或 6 位的模型。一般来说，量化是在资源使用和准确性之间进行权衡，而 4-6 位量化是大多数模型的最佳平衡点。

您会在模型名称中看到这一点，例如 gemma-3-27b-q5_k_l。这个相当晦涩的名称意味着 Gemma 3 模型，270 亿参数版本，以及 5 位量化。

这是我能提供的关于量化最快的速查表：通常，尽可能使用 q4 或 q5 模型。

然后根据其参数和您的内存选择模型。我的经验法则是：将参数数量乘以二，这就是您需要拥有的 RAM，以使模型有用。 我对“有用”的定义是模型以合理的速度运行（约 15 token/秒）并且具有足够大的上下文窗口（约 64K）以适用于大多数常见任务。

例如，假设您选择了 Google Gemma 3 4B，量化级别为 q4 或 q5。4 * 2 = 8，因此您需要 8 GB 的可用 VRAM 才能良好运行它。（是的，对于更懂技术的读者，这里有很多细微差别，但我们是为了入门。像这样将内存加倍考虑到了一个宽裕的上下文窗口和键/值缓存。）

那么，从第 1 部分来看，您可用的 VRAM 是多少？如果您有 16 GB 的显卡，您可以安全地良好运行 8B 模型，或任何低于该数字的模型。您可以轻松运行 Google Gemma 3 4B。是的，理论上您可以运行 Google Gemma 3 12B，但它会非常慢，并且上下文窗口（聊天中的可用短期记忆）会非常小，以至于没有什么用处。

在我的 Mac 上，我大约有 110 GB 的可用内存，这意味着我可以运行任何大小的 Gemma 模型，直至其最大尺寸 27B，并且它仍然可用且快速。在我当前的设置下，我可以运行高达 550 亿参数的模型。

当我们访问 Hugging Face 模型存储库，或查看界面中的模型目录时，这就为我们选择模型提供了一个基准。

我们可以按家族和参数查看模型，而无需过多考虑量化，至少在入门阶段是这样。

让我们继续讨论软件。

第 3 部分：软件 (Software)

现在我们已经了解了可以运行哪些模型，我们需要获取必要的软件来运行它们。没有人直接运行 AI 模型；AI 模型的核心本质上只是巨大的统计数据库。要利用模型，我们需要一个围绕它的接口。这类似于汽车；没有人坐在发动机缸体上开车上路。发动机缸体嵌入在汽车本身中，虽然发动机缸体至关重要——没有发动机汽车寸步难行——但没有汽车，发动机本身也无用。

对于想要开始使用本地AI模型的普通人来说，您会希望选择一个同时也内置了后端服务器的接口。可以像考虑 Web 一样思考 AI 接口，它有两个主要部分：服务器和客户端。

当您上网时，您的客户端——Web 浏览器，如 Safari、Chrome 或 Brave——会去与包含网站的别人的 Web 服务器进行交互。像 WP Engine 这样的公司拥有服务器——很多大型硬件——它们提供像 WordPress 这样的软件，并最终提供像 Trust Insights 网站 这样的网站。您两者都需要——没有服务器的客户端是无用的，反之亦然。

AI 模型的工作方式有些类似。有一个提供模型的服务器，以及一个与之交互的客户端。当您通过浏览器或应用程序访问 ChatGPT、Claude 或 Gemini 时，您正在使用客户端与那些大型科技公司运行的 AI 服务器进行对话。

在本地 AI 模型领域，有些软件包将两者捆绑在一起，既是客户端又是服务器。这是我们在最基础的层面上手本地 AI 时想要使用的。

对于不特别热衷于设置服务器的普通用户，我推荐两个软件包：AnythingLLM 和 LM Studio。这两个都是免费的；主要区别在于功能。AnythingLLM 内置了很多功能，如文档管理、语音识别等。它试图做很多事情，并且在很大程度上是成功的；它也具有我们都熟悉和使用的基本聊天式界面。

LM Studio 也提供了同样熟悉的聊天界面，但它试图成为一个更强大的服务器以及客户端。它特别适合当前的 M 系列 Mac，因为它支持 Apple 的 MLX AI 标准。MLX 版本的模型比非 MLX 模型运行速度快 5-8%。

您如何在这两者之间做决定？如果您计划使用 agent、API 或针对您的本地 AI 开发代码，我强烈建议使用 LM Studio（或者如果您有 Mac）。如果您计划仅将其作为最终用户消费者使用，就像您今天使用 ChatGPT 或 Gemini 的方式一样，那么 AnythingLLM 将是一个不错的选择。

这些是在您计算机上运行的标准应用程序，因此像安装任何其他软件一样安装它们即可。

第 4 部分：配置 (Configuration)

就像新安装的软件（如 Microsoft Word）需要一些配置或调整以使其对您的特定用例有用一样，AI 软件也需要一些配置才能使其有用。

我们首先必须决定使用哪个模型。有很多选择。开放模型的一个特点是，由于数量众多，不同的模型以擅长不同的任务而闻名，并且有许多专门为某种任务构建或调整的专用模型。这与像 Gemini、Claude 或 ChatGPT 这样的工具形成了对比，后者试图并且在很大程度上成功地擅长多种不同类型的任务。

让我们看看几个不同的模型家族以及它们擅长的领域。

• Google Gemma 3：Gemma 3 在遵循指令方面做得非常好，尤其是 12B 和 27B 版本。如果您的任务中指令遵循（如分步说明、工作流程等）很重要，Gemma 3 将很好地为您服务。Gemma 可以写作，但往往有点简洁。
• Meta Llama 3.3：虽然 Llama 4 已经上市，但对于大多数消费级硬件来说太大了。Llama 3.3 是当前可以在消费级硬件上运行的版本。Llama 3.3 非常适合非虚构写作。
• Mistral Small：Mistral 家族擅长多语言工作和写作。它能力很强，特别是当前的 Small 版本，Small 3 24B，一个 240 亿参数的模型。请记住，您需要有 48 GB 的 VRAM/内存才能充分利用它。
• DeepCoder：如果您专门使用生成式 AI 来编写代码，DeepCoder 是一个非常棒的编码模型，尤其擅长生成初稿。

一旦您选择了一个大小适合您内存和资源的模型，请在应用程序的界面中下载它。

在主聊天窗口或设置中，根据您使用的应用程序，您需要花点时间熟悉功能，并可能调整一些设置。一个比较有用的设置是名为“温度 (temperature)”的参数。您会在模型设置中看到它。

温度有什么作用？从根本上说，温度控制模型响应中随机性的水平。低温度意味着较少的随机性。高温度意味着更多的随机性。

您为什么要调整这个设置？有些任务是非常确定性的；您不希望模型过于富有创造力。例如，如果您要求模型将一些文本按一组定义的类别进行分类，您会将温度设置得很低，比如 0.5，以防止它随意地想出新的类别。

其他任务则更具概率性，比如创意写作。如果温度设置得太低，您会得到极其机械化的生成内容。温度在 0.7 到 1.0 之间的任何值都倾向于通过允许模型有更多自由来发挥创意，从而产生更具创意的写作。

对于那些习惯了像 ChatGPT 这样的界面的用户来说，这可能看起来不寻常。在幕后，像 ChatGPT 这样的服务具有完全相同的设置和控件；只是那些最终用户模型的设置通常由提供商设定，普通消费者无法控制或更改它们。

好了，您已经安装了软件。您已经下载并安装了模型。您已经配置了设置。您终于准备好开始使用本地 AI 了。

第 5 部分：使用 (Usage)

终于，我们来到了精彩的部分，对吧？嗯，精彩的部分出人意料地平淡：它就像您使用过的其他任何生成式AI大型语言模型一样。但在涉及开放模型和本地AI时，有几个重要的转折点需要了解。

还记得我们讨论过的参数数量吗？模型的参数越多，其性能往往越好。这既关系到指令遵循（即在您的提示中执行您告知它的操作），也关系到知识。更多的参数意味着更多的编码知识。

但除了真正非常大的模型，如 Llama 3.1 405B（4050 亿参数）、DeepSeek（6710 亿参数）以及少数其他模型外，大多数本地模型的参数实际上都低于 500 亿。在这种规模下，模型会有一些知识，但产生幻觉的风险非常高。

这意味着您必须为模型提供更多数据。这里有一个简单的例子。如果您问一个像 Gemma 3 4B 这样的小模型 Trust Insights 的 CEO 是谁，它会给出一个荒谬的答案。如果您提供了答案，它会完美地复述出来。

现在，您可能会（非常正确地）说，如果必须我们提供答案，那还有什么意义呢？嗯，现在我们进入了生成式 AI 的用例（您可以在我的新课程 《营销人员生成式AI用例》 中了解更多相关信息）以及较小模型擅长的领域。

• 提取 (Extraction)：从其他数据中提取数据
• 分类 (Classification)：组织数据
• 总结 (Summarization)：将大数据转化为小数据
• 改写 (Rewriting)：将数据从一种形式转换为另一种形式
• 综合 (Synthesis)：将小数据聚合成大数据
• 问答 (Question Answering)：回答关于您的数据或一般性的问题
• 生成 (Generation)：创造新数据

在本地 AI 方面，这里的前 5 个用例是它真正闪耀的地方。给定数据，即使是非常小的模型，如 Gemma 3 4B，也能胜任这些任务——而且它们的速度会快如闪电。

它们会在用例 6 和 7 上遇到困难，即当我们要求模型创建新数据时。例如，在不提供任何数据的情况下，要求 Gemma 3 推荐您所在地区的餐厅是行不通的。它只是没有足够的知识。如果在提供一个包含餐厅及其产品的庞大 JSON 文档的情况下问它，它会做得很好。

生成也是如此。例如，让它在没有任何背景数据的情况下写一篇关于 B2B 营销的博客文章，它会生成泛泛而谈的垃圾内容。它在任何一个领域都没有足够的知识来创造真正独特、引人入胜的内容，特别是当参数低于大约 100 亿时。如果给它您积累的简报和播客作为数据存储，它在生成内容方面可能会做得更好。

这些模型在重复性任务上表现出色，特别是如果您可以自动化它们。还记得上周关于 n8n 的时事通讯吗？？如果您可以将工作流连接到本地 AI 模型而不是基于云的服务，那么本地 AI 模型将是一个巨大的成本节省器。

第 6 部分：总结 (Wrapping Up)

在本期时事通讯中，我们主要关注了“如何做”，如果您拥有硬件以及像 LM Studio 或 AnythingLLM 这样的工具，您就处于有利位置，可以开始使用本地 AI 模型了。

关于本地 AI，尤其是在笔记本电脑上，最后一点提醒：全速运行 GPU 会消耗系统 100% 的能量。预计您的风扇会运转，甚至可能会耗尽电池——即使您的笔记本电脑插着电源！所有的生成式 AI 都非常耗电，所以如果您在您的机器上大量使用生成式 AI 模型，除非您有一台性能强劲的机器，否则不要指望您的机器能同时做很多其他事情。

请记住使用本地模型的主要原因：成本、隐私、灵活性、可持续性和可靠性。最先进的性能并不是使用它们的理由之一，所以如果您正在处理一个需要最先进性能的非常复杂的任务，请改用大型前沿模型。

我希望本指南能为您在本地运行生成式 AI 提供一个良好的起点。如果您想要更具战略性的概览，请观看我在 MAICON 2024 会议上关于开放模型和本地 AI 的演讲。尽管技术和策略上发生了很多变化，但战略大体上保持不变。

Almost Timely News: 🗞️ 로컬 AI 모델 시작하는 방법 (2025-04-20) :: 브라우저에서 보기

주요 공지

👉 마케터를 위한 생성형 AI 활용 사례 신규 강의가 오픈했습니다!

콘텐츠 진위성 선언

이번 주 뉴스레터는 100% 인간인 제가 작성했습니다. 이러한 공개가 왜 좋은 생각이며, 가까운 미래에 EU와 어떤 형태로든 비즈니스를 수행하는 모든 사람에게 요구될 수 있는지 알아보세요.

YouTube에서 이 뉴스레터 보기 📺

MP3 오디오 🎧 버전만 들으려면 여기를 클릭하세요 »

이번 주 생각: 로컬 AI 모델 시작하는 방법

LinkedIn에서 한 게시물이 크게 화제가 된 후, 로컬 AI 모델을 시작하는 방법에 대해 글을 쓸 때가 된 것 같습니다. 이번 뉴스레터에서는 이 문제에 대해 두 가지 주의 사항을 알려드리겠습니다. 첫째, 생성형 AI에 익숙하신 것보다 본질적으로 더 기술적인 내용이 될 것입니다. 우리는 브라우저 창을 열고, 원하는 AI 도구에 로그인하여 작업을 처리하는 데 익숙합니다. 이러한 도구를 가능하게 하는 배관 및 인프라에 대해 생각할 필요가 없었죠.

만약 이런 기술적인 내용이 불편하거나 (예: 회사 IT 정책으로 인해) 할 수 없다면, 편안하게 읽거나 이 이슈를 완전히 건너뛰셔도 좋습니다.

두 번째 주의 사항은 용어에 관한 것입니다. 이 분야에는 혼란스러운 용어가 많으므로, 몇 가지 정의를 설정해야 합니다. 제가 사용하는 몇 가지 용어는 다소 혼용될 수 있으므로, 기준을 세워봅시다:

• 로컬 AI(Local AI): 휴대폰부터 자체 온프레미스 데이터 센터까지, 여러분의 하드웨어에서 실행하는 생성형 AI 모델입니다. AI 모델이 실행되는 기계를 완전히 제어할 수 있는 모든 환경이 로컬 AI입니다.
• 오픈 모델/오픈 가중치 모델(Open model/open weights model): 모델 제작자가 온라인에서 무료로 배포하는 생성형 AI 모델입니다. 이 모델들을 사용하면 어디서든 실행할 수 있으며, 모델 제작자에게 사용료를 지불할 필요가 없습니다. 어떤 사람들은 이것을 오픈 소스 모델 또는 오픈 소스 AI라고 잘못 부르기도 하지만, 진정한 오픈 소스로 인정받기 위해 필요한 훈련 데이터 세트 자체를 배포하는 모델 제작자는 거의 없습니다.

기술적으로 이 둘은 같은 것이 아닙니다. 로컬 AI는 여러분과 여러분의 네트워크에 국한됩니다. 오픈 모델은 어디서든 실행될 수 있습니다. 예를 들어, IBM의 생성형 AI 보안 클라우드인 IBM WatsonX.ai에서도 오픈 모델을 실행할 수 있습니다. 전혀 로컬이 아니죠. 실행되는 기계에 대한 제어권이 없습니다. 하지만 많은 조직, 특히 IBM 클라우드 내에서 운영되고 IBM의 거버넌스 기술이 필요한 조직에게는 오픈 가중치 모델을 실행하기에 훌륭한 장소입니다.

ChatGPT와 같은 서비스가 매우 편리한데 왜 굳이 로컬 AI 모델을 사용하려고 하는지 이야기해야 할 것 같습니다. SaaS AI 서비스 대신 로컬 AI 모델을 사용하려는 데에는 다섯 가지 이유가 있습니다:

• 개인 정보 보호(Privacy): 로컬 하드웨어에서 모델을 실행하면 데이터가 시스템 밖으로 나가지 않습니다. 기기 자체의 개인 정보 보호 및 보안 수준을 유지할 수 있습니다. 이는 민감한 데이터를 다루는 모든 사람에게 매우 큰 매력입니다.
• 비용(Cost): 로컬 하드웨어에서 모델을 실행하면 운영 비용(주로 전기 요금)만 발생합니다. 이는 개발 과정의 일부로 모델에 수많은 API 호출을 할 수 있는 R&D와 같은 작업에 매우 중요합니다. 클라우드 제공업체를 사용하면 제품을 보여주거나 판매하기도 전에 막대한 비용이 발생할 수 있습니다. 로컬 모델을 사용하면 해당 비용을 크게 줄일 수 있으며, 충분히 성공적이라면 프로덕션 환경에서도 로컬 모델 사용을 정당화할 수 있습니다.
• 지속 가능성(Sustainability): AI 운영에 사용하는 전력이 적을수록 더 지속 가능합니다. 물론 제공업체가 대규모의 집중된 컴퓨팅 성능을 가질 때 규모의 경제가 분명히 존재하지만, 그들 모두 가능한 한 많은 전기를 끌어 모으려 한다는 점을 고려하면 AI가 엄청나게 자원 집약적이라는 것을 깨닫는 것은 그리 어려운 상상이 아닙니다. 로컬 모델을 잘 사용하면 전력 소비를 줄일 수 있습니다.
• 제어(Control): 로컬에서 모델을 실행하면 클라우드 서비스가 허용하는 것보다 훨씬 더 세밀하게 구성 방법을 완전히 제어할 수 있습니다. 이는 양날의 검입니다. 모델을 잘못 구성하여 작동 불능 상태로 만들 수도 있지만, 모델이 특정 작업을 수행하기를 원한다면 이러한 추가 제어 기능에 접근하는 것이 도움이 될 수 있습니다.
• 신뢰성(Reliability): 로컬 AI 모델은 여러분의 기기에서 실행됩니다. 일단 다운로드하면 여러분의 것입니다. 만약 OpenAI가 내일 문을 닫는다면 ChatGPT는 사라지겠지만, 여러분의 로컬 AI는 컴퓨터가 작동하는 한 계속 작동할 것입니다.

이러한 점들을 염두에 두고, 이를 설정하는 과정, 즉 HOW에 대해 자세히 알아보겠습니다. 이 뉴스레터의 비디오 버전을 보고 계시다면, 이러한 예시 중 일부를 더 자세히 볼 수 있습니다. 하드웨어, 모델, 소프트웨어, 구성, 사용 순서로 이야기해야 합니다.

파트 1: 하드웨어

기기에서 생성형 AI 모델을 실행하려면 충분한 리소스가 필요합니다. 생성형 AI 모델은 일반적으로 잘 실행되기 위해 아주 많은 메모리가 필요합니다. 컴퓨터에는 중요한 두 종류의 메모리가 있습니다 – 일반 컴퓨터 메모리(RAM)와 그래픽 메모리(VRAM 또는 비디오 RAM)입니다. 생성형 AI가 잘 실행되려면 VRAM이 가장 중요하며, 가장 변동성이 큰 변수입니다.

오늘날의 게이밍 PC 노트북은 일반적으로 12-16GB의 VRAM을 탑재하고 있지만, 일부 고급 게이밍 장비에는 더 많은 VRAM이 장착되어 있습니다. 오늘날의 Mac은 다른 종류입니다 – 2019년 이후의 Mac(M1, M2, M3, M4와 같은 이름의 M 시리즈 Mac)은 통합 메모리를 가지고 있어 일반 RAM과 VRAM이 동일한 것을 의미합니다. 컴퓨터가 자동으로 공유하는 큰 메모리 풀이 있습니다.

이는 PC에서는 종종 VRAM과 RAM 모두에 AI 모델을 로드할 수 있는 소프트웨어가 필요하며, AI 모델이 일반 RAM에서 실행될 때는 매우 느리기 때문에 매우 중요합니다.

여기서 기본적인 메시지는 간단합니다: PC를 구매/사용하는 경우, 감당할 수 있는 한 많은 VRAM을 확보하세요. Mac을 구매/사용하는 경우, 감당할 수 있는 한 많은 메모리를 확보하세요. 많을수록 항상 좋습니다.

컴퓨터 설정 어딘가에서(PC를 사용한 지 꽤 오래되었지만 작업 관리자나 시스템 환경설정에서 원하는 곳으로 갈 수 있을 것이고, 아마 Windows Copilot에게 물어보면 알려줄 것입니다) 사용할 수 있는 메모리 양을 알려줄 것입니다. 제 기억이 맞다면, Mac과 PC 모두 현재 컴퓨터 상태를 알려주는 활성 상태 보기(Activity Monitor) 앱이 있습니다.

메모리 상태를 찾고, 열려 있는 모든 응용 프로그램을 닫은 다음, 각 종류의 메모리가 얼마나 있는지 기록해 두세요.

예를 들어, 제 MacBook에서는 다른 아무것도 실행하지 않은 상태에서 다음과 같이 표시됩니다:

총 약 110GB의 메모리를 사용할 수 있음을 볼 수 있습니다. 이 정보가 곧 필요합니다.

파트 2: 모델

전체적으로 사용 가능한 메모리 양을 파악했으면, 모델 ‘쇼핑’을 시작할 수 있습니다. 쇼핑이라고 말하는 이유는 우리의 요구에 맞는 오픈 가중치 모델을 찾아야 하기 때문입니다. 모델 저장소인 Hugging Face에는 160만 개가 넘는 다양한 모델이 있습니다. 물론, 그중 다수는 특정 작업을 위해 특별히 제작되었으므로, 현재 성능이 우수한 몇 가지 주요 모델 계열에 집중할 것입니다.

일반 비즈니스 사용자에게 추천하는 세 가지 계열은 다음과 같습니다:

• Google Gemma
• Meta Llama
• Mistral

각 계열에는 다양한 모델 크기가 있습니다. 모델 이름에 모델이 포함하는 파라미터 수가 표시됩니다. 파라미터는 모델이 포함하는 지식과 정보의 양입니다. 예를 들어, Google Gemma 3 1B, 4B, 12B, 27B 등을 볼 수 있습니다. 이 숫자들은 10억 파라미터, 40억 파라미터 등을 나타냅니다.

일반적으로 파라미터가 많을수록 좋지만 제한이 있습니다. 파라미터가 큰 모델일수록 잘 실행되기 위해 더 많은 메모리가 필요합니다. 사용 가능한 메모리보다 큰 모델을 선택하면 모든 메모리를 소비하여 컴퓨터 전체가 멈추게 되어 말 그대로 컴퓨터가 다운될 수 있습니다.

파라미터가 작은 모델의 단점은 무엇일까요? 파라미터는 지식입니다. 파라미터가 적을수록 모델은 더 ‘멍청’해집니다. Google Gemma 1B와 같은 모델은 일관성은 있지만 배경 지식이 거의 없기 때문에 거의 모든 것을 환각(hallucinate)하여 꾸며낼 것입니다. Google Gemma 27B와 같은 모델은 훨씬 더 유창하고 지식이 풍부할 것입니다.

일반적으로 노트북에서 실행할 수 있는 오픈 모델은 우리가 익숙한 대규모 프론티어 모델보다 지식이 훨씬 적다는 점을 말하는 것이 중요합니다. ChatGPT의 GPT-4o 모델은 Google Gemini와 마찬가지로 수조 개의 파라미터를 가질 것으로 추정됩니다. 이에 대한 영향은 잠시 후에 더 자세히 이야기하겠습니다.

특정 모델 선택에 대해 자세히 알아보기 전에, 모델 선택의 매우 혼란스러운 측면인 양자화(quantization)에 대해 이야기해야 합니다.

모델 제작자는 가능한 가장 높은 정확도 형식으로 모델을 출시합니다. 우리가 이러한 버전의 모델과 상호 작용할 때, 모델은 최고 정확도 수준에서 작업을 수행하지만 메모리를 많이 차지합니다. 메모리를 미친 듯이 먹어 치우고 상당히 느리게 실행됩니다.

오픈 가중치 커뮤니티는 종종 모델 제작자가 만든 모델을 가져와 양자화를 수행하는데, 이는 일종의 압축입니다. 양자화는 모델의 정확도를 낮추지만 작동 속도를 훨씬 빠르게 만듭니다. 양자화의 수학적 측면에 대해서는 나중에 자세히 다룰 수 있지만, 간단히 말해 우리는 4, 5 또는 6비트로 양자화된 모델을 원합니다. 일반적으로 양자화는 리소스 사용량과 정확도 사이의 절충이며, 4-6비트 양자화는 대부분의 모델에 가장 적합한 지점입니다.

이는 gemma-3-27b-q5_k_l과 같은 모델 이름에서 볼 수 있습니다. 이 다소 난해한 이름은 Gemma 3 모델, 270억 파라미터 버전, 5비트 양자화를 의미합니다.

양자화에 대해 제가 제공할 수 있는 가장 빠른 치트 시트는 다음과 같습니다: 일반적으로 가능하면 q4 또는 q5 모델을 사용하세요.

그런 다음 파라미터와 메모리를 기준으로 모델을 선택하세요. 제 경험칙은 다음과 같습니다: 파라미터 수를 두 배로 늘리면 모델이 유용하게 작동하는 데 필요한 RAM 용량이 됩니다. 저는 유용함을 합리적인 속도(초당 15 토큰 정도)로 작동하고 대부분의 일반적인 작업에 유용한 충분히 큰 컨텍스트 창(약 64K)을 갖는 것으로 정의합니다.

예를 들어, q4 또는 q5 양자화된 Google Gemma 3 4B를 선택했다고 가정해 봅시다. 4 * 2 = 8이므로, 잘 실행하려면 8GB의 VRAM이 필요합니다. (네, 기술적인 분들을 위해 여기에 많은 미묘한 차이가 있지만, 우리는 시작하려는 것입니다. 이렇게 메모리를 두 배로 늘리는 것은 넉넉한 컨텍스트 창과 키/값 캐시를 고려한 것입니다.)

자, 1부에서 사용 가능한 VRAM은 얼마였나요? 16GB 그래픽 카드가 있다면 8B 모델이나 그 이하의 모델을 안전하게 잘 실행할 수 있습니다. Google Gemma 3 4B는 쉽게 실행할 수 있습니다. 네, 기술적으로는 Google Gemma 3 12B를 실행할 수 있지만, 너무 느리고 컨텍스트 창(채팅에서 사용 가능한 단기 메모리)이 너무 작아서 유용하지 않을 것입니다.

제 Mac에서는 약 110GB의 메모리를 사용할 수 있으므로, 최대 크기인 27B까지의 모든 Gemma 모델을 유용하고 빠르게 실행할 수 있습니다. 현재 설정으로 최대 550억 파라미터 모델까지 실행할 수 있습니다.

모델용 Hugging Face 저장소를 방문하거나 인터페이스의 모델 카탈로그를 볼 때, 이제 모델 선택의 기준선을 갖게 됩니다.

적어도 시작 단계에서는 양자화를 기본 사항 이상으로 고려하지 않고도 계열과 파라미터별로 모델을 볼 수 있습니다.

이제 소프트웨어로 넘어가겠습니다.

파트 3: 소프트웨어

이제 어떤 모델을 실행할 수 있는지 이해했으므로, 이를 실행하는 데 필요한 소프트웨어를 구해야 합니다. 아무도 AI 모델을 직접 실행하지 않습니다. AI 모델은 본질적으로 통계의 거대한 데이터베이스일 뿐입니다. 모델을 활용하려면 그 주변에 인터페이스가 필요합니다. 이는 자동차와 유사합니다. 아무도 엔진 블록 위에 앉아 길을 운전하지 않습니다. 엔진 블록은 자동차 자체에 내장되어 있으며, 엔진 블록이 중요하지만(엔진 없이는 자동차가 아무 데도 갈 수 없음), 자동차 없이는 엔진도 쓸모없습니다.

로컬 AI 모델을 시작하려는 일반 사용자는 백엔드 서버도 내장된 인터페이스를 선택하는 것이 좋습니다. AI 인터페이스를 웹과 같이 서버와 클라이언트라는 두 가지 주요 부분으로 생각해보세요.

웹 서핑을 할 때, 클라이언트(Safari, Chrome 또는 Brave와 같은 웹 브라우저)는 웹 사이트를 포함하는 다른 사람의 웹 서버와 인터페이스합니다. WP Engine과 같은 회사는 서버(많은 대형 하드웨어)를 가지고 있으며, 이는 WordPress와 같은 소프트웨어와 궁극적으로 Trust Insights 웹사이트와 같은 웹사이트를 제공합니다. 둘 다 필요합니다 – 서버 없는 클라이언트는 쓸모없고, 그 반대도 마찬가지입니다.

AI 모델도 다소 비슷하게 작동합니다. 모델을 제공하는 서버와 그와 인터페이스하는 클라이언트가 있습니다. 브라우저나 앱으로 ChatGPT, Claude 또는 Gemini를 방문할 때, 여러분은 클라이언트를 사용하여 해당 대형 기술 회사의 AI 서버와 통신하는 것입니다.

로컬 AI 모델 분야에는 클라이언트와 서버를 함께 묶은 소프트웨어 패키지가 있습니다. 이것이 가장 기본적인 수준에서 로컬 AI를 시작하기 위해 사용하고자 하는 것입니다.

서버 설정에 그다지 열성적이지 않은 일반 사용자에게 추천하는 두 가지 소프트웨어 패키지는 AnythingLLM과 LM Studio입니다. 둘 다 무료이며, 주요 차이점은 기능에 있습니다. AnythingLLM에는 문서 관리, 음성 인식 등 많은 기능이 내장되어 있습니다. 많은 것을 하려고 시도하고 대부분 성공합니다. 또한 우리 모두가 알고 사용하는 기본 채팅 스타일 인터페이스도 갖추고 있습니다.

LM Studio도 익숙한 채팅 인터페이스를 제공하지만, 클라이언트뿐만 아니라 더 강력한 서버가 되려고 합니다. 특히 Apple의 MLX AI 표준을 지원하므로 현재 M 시리즈 Mac에 좋습니다. 모델의 MLX 버전은 비 MLX 모델보다 5-8% 더 빠르게 실행됩니다.

둘 중 어떤 것을 선택해야 할까요? 에이전트, API를 사용하거나 로컬 AI에 대해 코드를 개발할 계획이라면 LM Studio를 강력히 추천합니다(또는 Mac을 사용하는 경우). 오늘날 ChatGPT나 Gemini를 사용하는 방식처럼 최종 사용자 소비자로서만 사용할 계획이라면 AnythingLLM이 좋은 선택이 될 것입니다.

이들은 컴퓨터에서 실행되는 표준 앱이므로, 다른 소프트웨어를 설치하는 것처럼 설치하세요.

파트 4: 구성

Microsoft Word와 같이 새로 설치된 소프트웨어가 특정 사용 사례에 유용하게 만들기 위해 약간의 구성이나 조정이 필요한 것처럼, AI 소프트웨어도 유용하게 만들기 위해 약간의 구성이 필요합니다.

먼저 어떤 모델을 사용할지 결정해야 합니다. 선택지는 매우 많습니다. 오픈 모델의 특이점 중 하나는 모델이 너무 많아서 서로 다른 모델이 서로 다른 작업에 능숙한 것으로 알려져 있으며, 한 종류의 작업을 위해 특별히 제작되거나 조정된 전문화된 모델이 많다는 것입니다. 이는 다양한 종류의 작업에 능숙하려고 시도하고 대체로 성공하는 Gemini, Claude 또는 ChatGPT와 같은 도구와 대조됩니다.

몇 가지 다른 모델 계열과 그들이 잘하는 것을 살펴보겠습니다.

• Google Gemma 3: Gemma 3는 특히 12B 및 27B 버전에서 지침을 매우 잘 따릅니다. 지침 따르기(단계별 지침, 워크플로우 등)가 중요한 작업이 있다면 Gemma 3가 도움이 될 것입니다. Gemma는 글을 쓸 수 있지만 다소 간결한 경향이 있습니다.
• Meta Llama 3.3: Llama 4가 시장에 나와 있지만 대부분의 소비자 하드웨어에는 너무 큽니다. Llama 3.3은 소비자 하드웨어에서 실행할 수 있는 현재 버전입니다. Llama 3.3은 논픽션 글쓰기에 적합합니다.
• Mistral Small: Mistral 계열은 다국어 작업과 글쓰기에 뛰어납니다. 특히 현재 Small 버전인 Small 3 24B(240억 파라미터 모델)는 매우 유능합니다. 제대로 활용하려면 48GB의 VRAM/메모리가 필요하다는 것을 기억하세요.
• DeepCoder: 생성형 AI를 특히 코드 작성에 사용한다면 DeepCoder는 코딩, 특히 초안 작성에 환상적인 모델입니다.

보유한 메모리와 리소스에 적합한 크기의 모델을 선택했으면, 앱 인터페이스에서 다운로드하세요.

사용 중인 앱에 따라 메인 채팅 창이나 설정에서 기능을 익히고 설정을 조정하는 데 잠시 시간을 할애하는 것이 좋습니다. 알아두면 유용한 설정 중 하나는 온도(temperature)라는 파라미터입니다. 모델 설정에서 이를 볼 수 있습니다.

온도는 무엇을 할까요? 기본적으로 온도는 모델 응답의 무작위성 수준을 제어합니다. 낮은 온도는 무작위성이 적다는 것을 의미합니다. 높은 온도는 무작위성이 더 많다는 것을 의미합니다.

왜 이걸 건드리고 싶을까요? 일부 작업은 매우 결정론적입니다. 모델이 너무 창의적이 되는 것을 원하지 않습니다. 예를 들어, 모델에게 정의된 범주 집합에서 일부 텍스트를 분류하도록 요청했다면, 임의로 새로운 범주를 만들어내는 것을 방지하기 위해 0.5와 같은 낮은 온도를 설정할 것입니다.

창의적인 글쓰기와 같은 다른 작업은 더 확률적입니다. 온도를 너무 낮게 설정하면 믿을 수 없을 정도로 로봇 같은 생성이 나옵니다. 0.7에서 1.0 사이의 온도는 모델이 창의적일 수 있는 더 많은 자유를 허용함으로써 더 창의적인 글쓰기를 산출하는 경향이 있습니다.

ChatGPT와 같은 인터페이스에 익숙한 사람들에게는 이것이 이상하게 보일 수 있습니다. 무대 뒤에서는 ChatGPT와 같은 서비스도 정확히 동일한 설정과 제어 기능을 가지고 있습니다. 단지 해당 최종 사용자 모델은 일반적으로 제공업체에 의해 설정되며 일반 소비자는 이를 제어하거나 변경할 능력이 없다는 것입니다.

자, 소프트웨어를 설치했습니다. 모델을 다운로드하고 설치했습니다. 설정을 구성했습니다. 드디어 로컬 AI를 사용할 준비가 되었습니다.

파트 5: 사용법

드디어 좋은 부분에 도달했군요, 그렇죠? 글쎄요, 좋은 부분은 놀랍게도 지루합니다. 여러분이 사용해 본 다른 모든 생성형 AI 대규모 언어 모델과 똑같습니다. 오픈 모델과 로컬 AI에 관해서 알아두어야 할 중요한 몇 가지 반전이 있습니다.

파라미터 수에 대해 이야기했던 것을 기억하시나요? 모델이 가진 파라미터가 많을수록 성능이 더 좋은 경향이 있다는 것을요? 이는 지침 따르기(즉, 프롬프트에서 지시한 대로 수행하는 것)와 지식 모두에 관련이 있습니다. 더 많은 파라미터는 더 많은 인코딩된 지식을 의미합니다.

하지만 Llama 3.1 405B(4050억 파라미터), DeepSeek(6710억 파라미터) 및 소수의 다른 모델과 같은 정말, 정말 큰 모델을 제외하고는 대부분의 로컬 모델은 실질적으로 500억 파라미터 미만이 될 것입니다. 그 규모에서는 모델이 약간의 지식을 가지겠지만, 환각의 위험이 매우 높습니다.

이는 여러분이 더 많은 데이터를 가져와야 한다는 것을 의미합니다. 간단한 예를 들어보겠습니다. Gemma 3 4B와 같은 작은 모델에게 Trust Insights의 CEO가 누구인지 물으면 터무니없는 답변을 할 것입니다. 답을 제공하면 완벽하게 암송할 것입니다.

이제 (아주 정확하게) 답을 제공해야 한다면 무슨 소용이냐고 말할 수 있습니다. 글쎄요, 이제 생성형 AI의 사용 사례(제 신규 강의 마케터를 위한 생성형 AI 활용 사례에서 더 자세히 알아볼 수 있습니다)와 소규모 모델이 잘하는 것에 대해 알아봅니다.

• 추출(Extraction): 다른 데이터에서 데이터 가져오기
• 분류(Classification): 데이터 정리하기
• 요약(Summarization): 큰 데이터를 작은 데이터로 만들기
• 재작성(Rewriting): 데이터를 한 형태에서 다른 형태로 변환하기
• 합성(Synthesis): 작은 데이터를 집계하여 큰 데이터로 만들기
• 질의응답(Question Answering): 데이터나 일반적인 질문에 답하기
• 생성(Generation): 새로운 데이터 만들기

로컬 AI에 관해서는 여기 처음 5가지 사용 사례가 진정으로 빛을 발하는 부분입니다. 데이터가 주어지면 Gemma 3 4B와 같은 매우 작은 모델조차도 매우 유능한 작업을 수행할 수 있으며, 번개처럼 빠르게 처리할 것입니다.

그들이 어려움을 겪을 부분은 우리가 모델에게 새로운 데이터를 생성하도록 요청하는 6번과 7번 사용 사례입니다. 예를 들어, Gemma 3에게 아무런 데이터도 제공하지 않고 해당 지역의 레스토랑 추천을 요청하면 잘 되지 않을 것입니다. 충분한 지식이 없습니다. 레스토랑과 그들이 제공하는 메뉴에 대한 대규모 JSON 문서를 제공하면서 물어보면 잘 해낼 것입니다.

생성도 마찬가지입니다. 배경 데이터 없이 B2B 마케팅에 대한 블로그 게시물을 작성하도록 요청하면 일반적인 쓰레기가 나올 것입니다. 어떤 한 분야에 대해서도 정말 독특하고 설득력 있는 콘텐츠를 만들 만큼 충분한 지식이 없습니다. 특히 약 100억 파라미터 미만에서는 더욱 그렇습니다. 뉴스레터와 팟캐스트 백로그를 데이터 저장소로 제공하면 무언가를 생성하는 데 훨씬 더 잘할 가능성이 높습니다.

이러한 모델이 빛을 발하는 곳은 반복적인 작업, 특히 자동화할 수 있는 경우입니다. n8n에 대한 지난주 뉴스레터를 기억하시나요? 워크플로우를 클라우드 기반 서비스 대신 로컬 AI 모델을 사용하도록 연결할 수 있다면 엄청난 비용 절감 효과를 얻을 수 있습니다.

파트 6: 마무리하며

이번 뉴스레터에서는 주로 ‘어떻게(how)’에 초점을 맞췄습니다. 하드웨어와 LM Studio 또는 AnythingLLM과 같은 도구가 있다면 로컬 AI 모델을 활용하기 시작할 좋은 위치에 있습니다.

로컬 AI, 특히 노트북 사용 시 마지막 주의 사항: GPU를 최대 성능으로 사용하면 시스템 에너지의 100%를 소모합니다. 팬이 돌아갈 것으로 예상하고, 노트북이 연결된 상태에서도 배터리가 소모될 수 있습니다! 모든 생성형 AI는 엄청나게 전력을 많이 소비하므로, 기기에서 생성형 AI 모델을 많이 사용한다면, 괴물 같은 기기가 아닌 이상 동시에 다른 많은 작업을 수행하기를 기대하지 마세요.

로컬 모델을 사용하는 주요 이유를 기억하세요: 비용, 개인 정보 보호, 유연성, 지속 가능성 및 신뢰성입니다. 최첨단 성능은 사용 이유 중 하나가 아니므로, 최첨단 성능을 요구하는 매우 복잡한 작업을 처리하는 경우 대신 대규모 프론티어 모델을 사용하세요.

이 가이드가 로컬에서 실행되는 생성형 AI를 위한 훌륭한 출발점을 제공하기를 바랍니다. 더 전략적인 둘러보기를 원하시면, MAICON 2024 컨퍼런스에서 오픈 모델과 로컬 AI에 대해 제가 발표한 이 강연을 시청하세요. 많은 기술적 및 전술적 변화가 있었지만, 전략은 대체로 동일하게 유지됩니다.

Apa Yang Ada Di Fikiran Saya: Cara Bermula dengan Model AI Tempatan

Selepas satu hantaran menjadi tular di LinkedIn, saya rasa sudah tiba masanya untuk menulis cara bermula dengan model AI tempatan. Saya akan memberikan dua peringatan mengenai isu surat berita ini. Pertama, ia secara semula jadinya akan lebih teknikal daripada yang mungkin anda biasa dengan AI generatif. Anda dan saya biasa membuka tetingkap pelayar, log masuk ke alat AI pilihan kita, dan menyelesaikan tugasan. Kita tidak pernah perlu memikirkan tentang selok-belok dan infrastruktur yang membolehkan alat tersebut berfungsi.

Jika anda tidak selesa atau tidak dapat (disebabkan oleh polisi IT syarikat, contohnya) untuk melakukan perkara yang lebih teknikal ini, maka sila berehat dan membaca sahaja, atau langkau sahaja isu ini sepenuhnya.

Peringatan kedua adalah mengenai bahasa. Terdapat banyak istilah yang mengelirukan dalam bidang ini, jadi kita patut menetapkan beberapa definisi. Saya menggunakan beberapa istilah berbeza yang agak boleh ditukar ganti, jadi mari kita jelaskan:

• AI Tempatan: model AI generatif yang anda jalankan pada perkakasan anda, dari telefon anda hingga ke pusat data di premis anda sendiri. Mana-mana persekitaran di mana anda mempunyai kawalan penuh terhadap mesin yang menjalankan model AI adalah AI tempatan.
• Model terbuka/model wajaran terbuka: model AI generatif yang diedarkan secara percuma dalam talian oleh pembuat model. Model ini membolehkan anda menjalankannya di mana-mana sahaja, dan anda tidak perlu membayar pembuat model untuk menggunakannya. Sesetengah orang akan tersilap memanggilnya model sumber terbuka atau AI sumber terbuka, tetapi hampir tiada pembuat model yang mengedarkan set data latihan itu sendiri yang diperlukan untuk melayakkannya sebagai sumber terbuka sebenar.

Ini secara teknikalnya BUKAN perkara yang sama. AI Tempatan adalah setempat kepada anda dan rangkaian anda. Model terbuka boleh dijalankan di mana-mana sahaja. Contohnya, anda boleh menjalankan model terbuka dalam IBM WatsonX.ai, awan selamat AI generatif IBM. Ia sama sekali bukan setempat. Anda tiada kawalan terhadap mesin yang menjalankannya. Tetapi bagi banyak organisasi, terutamanya yang berjalan di dalam awan IBM dan memerlukan teknologi tadbir urus IBM, ia adalah tempat yang bagus untuk menjalankan model wajaran terbuka.

Kita mungkin patut berbincang tentang MENGAPA anda mahu melakukan ini, sedangkan perkhidmatan seperti ChatGPT begitu mudah. Terdapat lima sebab anda mungkin mahu menggunakan model AI tempatan berbanding perkhidmatan AI SaaS:

• Privasi: apabila anda menjalankan model pada perkakasan anda secara tempatan, tiada data yang pernah meninggalkan sistem anda. Anda mempunyai privasi dan keselamatan sebanyak mesin anda sendiri. Ini adalah tarikan BESAR bagi sesiapa yang bekerja dengan data sensitif.
• Kos: apabila anda menjalankan model pada perkakasan anda secara tempatan, kosnya ialah kos operasi anda (biasanya elektrik). Ini sangat penting untuk perkara seperti R&D di mana anda mungkin membuat banyak panggilan API kepada model sebagai sebahagian daripada proses pembangunan anda. Menggunakan penyedia awan, ini boleh mengakibatkan bil yang besar sebelum anda mempunyai produk untuk ditunjukkan atau dijual. Menggunakan model tempatan mengurangkan kos tersebut dengan ketara – dan mungkin cukup berjaya sehingga anda boleh mewajarkan penggunaan model tempatan walaupun dalam pengeluaran.
• Kelestarian: semakin kurang kuasa yang anda gunakan untuk mengendalikan AI, semakin lestari ia. Ya, jelas terdapat ekonomi skala apabila penyedia mempunyai kuasa pengkomputeran besar-besaran dan tertumpu, tetapi memandangkan mereka semua ingin menyedut sebanyak mungkin elektrik, bukanlah satu imaginasi yang keterlaluan untuk menyedari AI sangat lapar sumber. Menggunakan model tempatan boleh mengurangkan penggunaan kuasa tersebut jika dilakukan dengan baik.
• Kawalan: apabila anda menjalankan model secara tempatan, anda mempunyai kawalan penuh terhadap cara ia dikonfigurasi, jauh lebih banyak daripada mana-mana perkhidmatan awan yang akan membenarkan anda. Ini adalah pedang bermata dua; anda boleh salah konfigurasi model sehingga ia menjadi tidak berfungsi – tetapi jika ada perkara khusus yang anda mahu model lakukan, akses kepada kawalan tambahan tersebut boleh membantu.
• Kebolehpercayaan: model AI tempatan berjalan pada mesin anda. Sebaik sahaja anda memuat turunnya, ia milik anda. Jika OpenAI ditutup esok, ChatGPT akan hilang, tetapi AI tempatan anda akan terus berfungsi selagi komputer anda berfungsi.

Dengan mengambil kira perkara ini, mari kita teliti proses BAGAIMANA untuk menyediakan perkara ini. Jika anda menonton versi video surat berita ini, anda akan melihat beberapa contoh ini dengan lebih terperinci. Kita perlu membincangkan perkakasan, model, perisian, konfigurasi, dan penggunaan, mengikut urutan itu.

Bahagian 1: Perkakasan

Untuk menjalankan model AI generatif pada mesin anda, anda memerlukan sumber yang mencukupi. Model AI generatif biasanya memerlukan memori yang sangat banyak untuk berjalan lancar. Komputer anda mempunyai dua jenis memori yang penting – memori komputer biasa (RAM), dan memori grafik (VRAM, atau RAM video). Agar AI generatif berjalan lancar, VRAM adalah yang paling penting – dan pemboleh ubah yang paling tidak menentu.

Laptop PC permainan hari ini biasanya dilengkapi dengan 12-16 GB VRAM, walaupun beberapa rig permainan mewah dilengkapi dengan lebih banyak lagi. Mac hari ini adalah berbeza – Mac sejak 2019 (Mac siri-M dengan nama seperti M1, M2, M3, M4) mempunyai memori dikongsi, yang bermaksud RAM biasa dan VRAM adalah perkara yang sama. Terdapat satu takungan besar yang dikongsi secara automatik oleh komputer.

Ini sangat penting kerana pada PC, anda sering memerlukan perisian yang boleh memuatkan model AI pada kedua-dua VRAM dan RAM anda, dan apabila model AI berjalan pada RAM biasa, ia p-e-r-l-a-h-a-n.

Mesej asas di sini mudah: jika anda membeli/menggunakan PC, dapatkan sebanyak mungkin VRAM yang anda mampu. Jika anda membeli/menggunakan Mac, dapatkan sebanyak mungkin memori yang anda mampu. Lebih banyak sentiasa lebih baik.

Komputer anda, di suatu tempat dalam tetapannya (sudah agak lama saya tidak menggunakan PC tetapi saya rasa sama ada Task Manager atau System Preferences akan membawa anda ke tempat yang anda mahu tuju, dan anda mungkin boleh bertanya kepada Windows Copilot untuk memberitahu anda) akan memberitahu anda berapa banyak memori yang anda ada untuk digunakan. Jika saya ingat dengan betul, kedua-dua Mac dan PC mempunyai aplikasi Activity Manager yang memberitahu anda keadaan semasa komputer anda.

Cari status memori anda, tutup semua aplikasi yang terbuka, dan catatkan berapa banyak setiap jenis memori yang anda ada.

Contohnya, pada MacBook saya, inilah yang saya lihat tanpa apa-apa lagi berjalan:

Anda boleh lihat bahawa saya mempunyai kira-kira 110 GB jumlah memori tersedia. Kita akan perlukan maklumat ini sebentar lagi.

Bahagian 2: Model

Sebaik sahaja kita mengetahui berapa banyak memori yang tersedia secara keseluruhan, kita boleh mula ‘membeli-belah’ untuk model. Saya katakan membeli-belah kerana kita perlu mencari model wajaran terbuka yang sesuai dengan keperluan kita. Di repositori model Hugging Face, terdapat lebih 1.6 juta model berbeza untuk dipilih. Sememangnya, banyak daripadanya dibina khas untuk tugas khusus, jadi kita akan fokus pada beberapa keluarga model besar yang kini berprestasi tinggi.

Tiga keluarga yang saya syorkan untuk pengguna perniagaan biasa ialah:

• Google Gemma
• Meta Llama
• Mistral

Dalam setiap keluarga, terdapat saiz model yang berbeza. Anda akan melihat ini disenaraikan dalam nama model, iaitu bilangan parameter yang terkandung dalam model tersebut. Parameter ialah ukuran berapa banyak pengetahuan dan maklumat yang terkandung dalam model. Contohnya, anda akan melihat perkara seperti Google Gemma 3 1B, 4B, 12B, 27B, dll. Nombor tersebut menunjukkan 1 bilion parameter, 4 bilion parameter, dsb.

Secara amnya, lebih banyak lebih baik TETAPI ada batasannya: semakin besar model dari segi parameter, semakin banyak memori yang diperlukan untuk berjalan lancar. Jika anda memilih model yang lebih besar daripada memori yang anda ada, ia secara literal akan menyebabkan komputer anda ranap dengan menggunakan semua memori dan melumpuhkan seluruh komputer anda.

Apakah kompromi dengan model parameter yang lebih kecil? Parameter adalah pengetahuan. Semakin sedikit parameter, semakin kurang bijak model itu. Model seperti Google Gemma 1B adalah koheren tetapi akan berhalusinasi tentang hampir segalanya, mereka-reka cerita kerana ia hampir tiada pengetahuan latar belakang. Model seperti Google Gemma 27B akan jauh lebih fasih dan berpengetahuan.

Penting untuk mengatakan bahawa model terbuka secara amnya yang boleh anda jalankan pada komputer riba akan jauh kurang berpengetahuan berbanding model perintis besar yang biasa kita gunakan. Model GPT-4o ChatGPT dianggarkan mempunyai trilion parameter, begitu juga Google Gemini. Kita akan bercakap lebih lanjut mengenai implikasi ini sebentar lagi.

Sebelum kita mendalami pemilihan model khusus, kita perlu bercakap tentang aspek yang sangat mengelirukan dalam memilih model: pengkuantitian.

Pembuat model mengeluarkan model mereka dalam format ketepatan tertinggi yang mungkin. Apabila kita berinteraksi dengan versi model tersebut, ia melaksanakan tugas pada tahap ketepatan tertingginya – tetapi ia adalah pelahap memori. Ia menggunakan memori dengan banyak dan berjalan agak perlahan.

Komuniti wajaran terbuka sering mengambil model yang dibuat oleh pembuat model dan melakukan pengkuantitian padanya, yang merupakan sejenis pemampatan. Apa yang dilakukannya ialah mengurangkan ketepatan model, tetapi menjadikannya jauh lebih pantas untuk beroperasi. Kita boleh mendalami matematik pengkuantitian lain kali, tetapi versi ringkasan pantasnya ialah kita mahukan model yang dikuantitikan pada 4, 5, atau 6 bit. Secara amnya, pengkuantitian adalah kompromi antara penggunaan sumber dan ketepatan, dan pengkuantitian 4-6 bit adalah titik optimum bagi kebanyakan model.

Anda melihat ini dalam nama model, seperti gemma-3-27b-q5_k_l. Nama yang agak arkana ini bermaksud model Gemma 3, versi 27 bilion parameter, dan pengkuantitian 5 bit.

Berikut adalah ringkasan terpantas yang boleh saya tawarkan mengenai pengkuantitian: secara amnya, gunakan sama ada model q4 atau q5 bila-bila masa anda boleh.

Kemudian pilih model berdasarkan parameternya dan memori anda. Petua praktikal saya ialah: ambil bilangan parameter, gandakannya, dan itulah RAM yang anda perlukan agar model itu berguna. Saya mendefinisikan berguna sebagai model yang beroperasi pada kelajuan yang munasabah (kira-kira 15 token/saat) dan mempunyai tetingkap konteks yang cukup besar (kira-kira 64K) untuk berguna bagi kebanyakan tugas biasa.

Contohnya, katakan anda memilih Google Gemma 3 4B, pada pengkuantitian q4 atau q5. 4 * 2 = 8, jadi anda perlukan 8 GB VRAM tersedia untuk menjalankannya dengan baik. (Ya, bagi mereka yang lebih teknikal, terdapat banyak nuansa di sini, tetapi kita cuba untuk bermula. Menggandakan memori seperti ini mengambil kira tetingkap konteks yang besar dan cache kunci/nilai.)

Jadi dari bahagian 1, apakah VRAM tersedia anda? Jika anda mempunyai kad grafik 16 GB, anda boleh menjalankan model 8B dengan selamat, atau apa sahaja di bawah nombor itu. Anda boleh menjalankan Google Gemma 3 4B dengan mudah. Ya, secara teknikalnya anda boleh menjalankan Google Gemma 3 12B, tetapi ia akan menjadi sangat perlahan dan dengan tetingkap konteks yang sangat kecil (memori jangka pendek yang tersedia dalam sembang) sehingga ia tidak akan berguna.

Pada Mac saya, saya mempunyai kira-kira 110 GB memori tersedia, yang bermaksud saya boleh menjalankan mana-mana saiz model Gemma sehingga saiz maksimumnya 27B dan ia boleh digunakan serta pantas. Saya boleh menjalankan model sehingga 55 bilion parameter pada persediaan semasa saya.

Apabila kita melawat repositori Hugging Face untuk model, atau melihat katalog model dalam antara muka, ini kini memberi kita garis dasar untuk memilih model.

Kita boleh melihat model mengikut keluarga dan parameter tanpa perlu mengambil kira pengkuantitian melebihi asas-asasnya, sekurang-kurangnya untuk bermula.

Mari beralih kepada perisian.

Bahagian 3: Perisian

Sekarang kita sudah mempunyai pemahaman tentang model apa yang boleh kita jalankan, kita perlu mendapatkan perisian yang diperlukan untuk menjalankannya. Tiada siapa yang menjalankan model AI secara langsung; model AI pada dasarnya hanyalah pangkalan data statistik yang sangat besar pada terasnya. Untuk menggunakan model, kita memerlukan antara muka di sekelilingnya. Ini sama seperti kereta; tiada siapa yang memandu di jalan raya sambil duduk di atas blok enjin. Blok enjin tertanam di dalam kereta itu sendiri, dan walaupun blok enjin itu kritikal – kereta tidak boleh pergi ke mana-mana tanpa enjin – enjin itu juga tidak berguna tanpa kereta.

Bagi orang biasa yang ingin bermula dengan model AI tempatan, anda perlu memilih antara muka yang juga mempunyai pelayan ‘back end’ terbina di dalamnya. Fikirkan tentang antara muka AI seperti anda memikirkan tentang Web, dengan dua bahagian utama, pelayan dan klien.

Apabila anda melayari web, klien anda – pelayar web, seperti Safari atau Chrome atau Brave – keluar dan berinteraksi dengan pelayan web orang lain yang mengandungi laman web tersebut. Syarikat seperti WP Engine mempunyai pelayan – banyak daripadanya, perkakasan besar – yang menyajikan perisian seperti WordPress dan akhirnya laman web seperti laman web Trust Insights. Anda perlukan kedua-duanya – klien tanpa pelayan tidak berguna, dan begitu juga sebaliknya.

Model AI berfungsi agak serupa. Terdapat pelayan yang menyajikan model, dan klien yang berinteraksi dengannya. Apabila anda melawat ChatGPT atau Claude atau Gemini melalui pelayar atau aplikasi, anda menggunakan klien untuk bercakap dengan pelayan AI yang berjalan di syarikat teknologi besar tersebut.

Dalam ruang model AI tempatan, terdapat pakej perisian yang menggabungkan kedua-duanya, yang merupakan klien dan pelayan. Inilah yang kita mahu gunakan untuk bermula dengan AI tempatan pada peringkat paling asas.

Terdapat dua pakej perisian yang saya syorkan untuk orang biasa yang tidak begitu teruja untuk menyediakan pelayan: AnythingLLM dan LM Studio. Kedua-duanya adalah percuma; perbezaan utama adalah dalam fungsi. AnythingLLM mempunyai BANYAK perkara terbina dalam, seperti pengurusan dokumen, pengecaman pertuturan, dsb. Ia cuba melakukan banyak perkara dan sebahagian besarnya ia berjaya; ia juga mempunyai antara muka gaya sembang asas yang kita semua kenali dan gunakan.

LM Studio menyediakan antara muka sembang yang biasa juga, tetapi cuba menjadi pelayan yang lebih mantap serta klien. Ia sangat baik untuk Mac siri-M semasa kerana ia menyokong standard MLX AI Apple. Versi MLX bagi sesuatu model berjalan 5-8% lebih pantas daripada model bukan MLX.

Bagaimana anda membuat keputusan antara kedua-duanya? Jika anda bercadang untuk menggunakan ejen, API, atau membangunkan kod terhadap AI tempatan anda, saya sangat mencadangkan LM Studio (Atau jika anda mempunyai Mac). Jika anda bercadang untuk hanya menggunakannya sebagai pengguna akhir, cara anda menggunakan ChatGPT atau Gemini hari ini, maka AnythingLLM adalah pilihan yang baik.

Ini adalah aplikasi standard yang berjalan pada komputer anda, jadi pasangkannya seperti anda memasang mana-mana perisian lain.

Bahagian 4: Konfigurasi

Sama seperti perisian yang baru dipasang seperti Microsoft Word memerlukan beberapa konfigurasi atau penyesuaian untuk menjadikannya berguna bagi kes penggunaan khusus anda, begitu juga perisian AI memerlukan beberapa konfigurasi untuk menjadikannya berguna.

Pertama, kita perlu memutuskan model mana yang hendak digunakan. Terdapat banyak pilihan. Salah satu keunikan model terbuka ialah dengan begitu banyaknya model, model yang berbeza diketahui baik dalam tugas yang berbeza, dan terdapat banyak model khusus yang dibina khas atau ditala untuk satu jenis tugas. Ini berbeza dengan alat seperti Gemini, Claude, atau ChatGPT yang cuba dan sebahagian besarnya berjaya menjadi baik dalam pelbagai jenis tugas.

Mari kita lihat beberapa keluarga model yang berbeza dan kelebihan masing-masing.

• Google Gemma 3: Gemma 3 melakukan tugas mengikut arahan dengan sangat baik, terutamanya versi 12B dan 27B. Jika anda mempunyai tugas di mana arahan langkah demi langkah, aliran kerja, dsb. adalah penting, Gemma 3 akan berkhidmat dengan baik untuk anda. Gemma boleh menulis tetapi cenderung agak ringkas.
• Meta Llama 3.3: Walaupun Llama 4 sudah berada di pasaran, ia terlalu besar untuk kebanyakan perkakasan pengguna. Llama 3.3 adalah versi semasa yang boleh dijalankan pada perkakasan pengguna. Llama 3.3 agak sesuai untuk penulisan bukan fiksyen.
• Mistral Small: Keluarga Mistral cemerlang dalam kerja pelbagai bahasa dan penulisan. Ia sangat berkebolehan, terutamanya versi Small semasa, Small 3 24B, model 24 bilion parameter. Ingat anda perlukan 48 GB VRAM/memori untuk memanfaatkannya sepenuhnya.
• DeepCoder: Jika anda menggunakan AI generatif khusus untuk menulis kod, DeepCoder adalah model yang hebat untuk pengekodan, terutamanya draf pertama.

Sebaik sahaja anda memilih model yang bersaiz sesuai untuk memori dan sumber yang anda ada, muat turunnya dalam antara muka aplikasi.

Dalam tetingkap sembang utama atau dalam tetapan, bergantung pada aplikasi apa yang anda gunakan, anda perlu mengambil sedikit masa untuk membiasakan diri dengan ciri-ciri serta mungkin mengubah suai beberapa tetapan. Salah satu tetapan yang lebih berguna untuk diketahui ialah parameter yang dipanggil suhu (temperature). Anda akan melihat ini dalam tetapan model.

Apa fungsi suhu? Pada asasnya, suhu mengawal tahap kerawakan dalam respons model. Suhu rendah bermaksud kurang rawak. Suhu yang lebih tinggi bermaksud lebih rawak.

Mengapa anda mahu mengubah suai ini? Sesetengah tugas adalah sangat deterministik; anda tidak mahu model menjadi terlalu kreatif. Contohnya, jika anda meminta model untuk mengklasifikasikan teks ke dalam set kategori yang ditetapkan, anda akan menetapkan suhu rendah, seperti 0.5, untuk mengelakkannya daripada secara sewenang-wenangnya mencipta kategori baharu.

Tugas lain lebih bersifat probabilistik, seperti penulisan kreatif. Tetapkan suhu terlalu rendah, dan anda mendapat penjanaan yang sangat robotik. Suhu antara 0.7 hingga 1.0 cenderung menghasilkan penulisan yang lebih kreatif dengan membenarkan model lebih kebebasan untuk menjadi kreatif.

Bagi mereka yang biasa dengan antara muka seperti ChatGPT, ini mungkin kelihatan luar biasa. Di sebalik tabir, perkhidmatan seperti ChatGPT mempunyai tetapan dan kawalan yang sama; cuma model pengguna akhir tersebut biasanya ditetapkan oleh penyedia dan pengguna biasa tidak mempunyai keupayaan untuk mengawalnya atau mengubahnya.

Baiklah, jadi anda sudah memasang perisian anda. Anda sudah memuat turun dan memasang model anda. Anda sudah mengkonfigurasi tetapan anda. Anda akhirnya bersedia untuk mula menggunakan AI tempatan.

Bahagian 5: Penggunaan

Akhirnya, kita sampai ke bahagian yang menarik, bukan? Nah, bahagian yang menarik ini mengejutkan, ia agak membosankan: ia sama seperti setiap model bahasa besar AI generatif lain yang pernah anda gunakan. Terdapat beberapa kelainan yang penting untuk diketahui apabila berkaitan dengan model terbuka dan AI tempatan.

Ingat bagaimana kita bercakap tentang kiraan parameter, bagaimana semakin banyak parameter yang dimiliki model, semakin baik prestasinya? Ini relevan untuk kedua-dua keupayaan mengikut arahan (iaitu melakukan apa yang anda arahkan dalam prom anda) serta pengetahuan. Lebih banyak parameter bermaksud lebih banyak pengetahuan terkod.

Tetapi kecuali untuk model yang sangat, sangat besar seperti Llama 3.1 405B (405 bilion parameter), DeepSeek (671 bilion parameter), dan segelintir yang lain, kebanyakan model tempatan secara efektif akan berada di bawah 50 bilion parameter. Pada skala itu, model akan mempunyai sedikit pengetahuan, tetapi risiko halusinasi sangat tinggi.

Ini bermakna anda perlu membawa lebih banyak data. Berikut adalah contoh mudah. Jika anda bertanya kepada model kecil seperti Gemma 3 4B siapa CEO Trust Insights, ia akan memberikan jawapan yang tidak masuk akal. Jika anda memberikan jawapannya, ia akan mengulanginya dengan sempurna.

Sekarang, anda mungkin berkata (dengan betul) bahawa jika kita perlu memberikan jawapannya, apa gunanya? Nah, sekarang kita masuk ke dalam kes penggunaan AI generatif (yang boleh anda pelajari lebih lanjut dalam kursus baharu saya, Kes Penggunaan AI Generatif untuk Pemasar) dan apa yang model lebih kecil bagus lakukan.

• Pengekstrakan: keluarkan data daripada data lain
• Pengelasan: susun data
• Peringkasan: jadikan data besar kepada data kecil
• Penulisan semula: ubah data dari satu bentuk ke bentuk lain
• Sintesis: ambil data kecil dan kumpulkan menjadi data besar
• Penjawapan Soalan: jawab soalan tentang data anda atau secara umum
• Penjanaan: hasilkan data baharu

Apabila berkaitan dengan AI tempatan, 5 kes penggunaan pertama di sini adalah di mana ia benar-benar menyerlah. Dengan data yang diberikan, walaupun model yang sangat kecil seperti Gemma 3 4B boleh melakukan tugas dengan sangat cekap – dan ia akan melakukannya sepantas kilat juga.

Kelemahannya adalah pada kes penggunaan 6 dan 7, apabila kita meminta model untuk mencipta data baharu. Contohnya, meminta Gemma 3 untuk cadangan restoran di kawasan anda tanpa memberikan sebarang data tidak akan berjalan lancar. Ia просто tidak mempunyai pengetahuan yang cukup. Tanya ia sambil memberikannya dokumen JSON besar mengenai restoran dan tawaran mereka, dan ia akan melakukannya dengan baik.

Perkara yang sama berlaku untuk penjanaan. Minta ia menulis, contohnya, catatan blog tentang pemasaran B2B tanpa sebarang data latar belakang dan ia akan menghasilkan hasil generik yang tidak bermutu. Tidak cukup pengetahuan dalam mana-mana domain tertentu untuk ia mencipta kandungan yang benar-benar unik dan menarik, terutamanya apabila anda berada di bawah kira-kira 10 bilion parameter. Berikan ia koleksi surat berita dan podcast anda sebagai simpanan data, dan kemungkinan besar ia akan melakukan jauh lebih baik dalam menjana sesuatu.

Di mana model ini menyerlah adalah pada tugas berulang, terutamanya jika anda boleh mengautomasikannya. Ingat surat berita minggu lepas tentang n8n? Model AI tempatan akan menjadi penjimat kos yang besar jika anda boleh menyambungkan aliran kerja untuk menggunakannya berbanding perkhidmatan berasaskan awan.

Bahagian 6: Penutup

Kita melihat kebanyakannya pada aspek cara dalam isu surat berita ini, dan jika anda mempunyai perkakasan dan alat seperti LM Studio atau AnythingLLM, anda berada dalam kedudukan yang baik untuk mula menggunakan model AI tempatan.

Satu peringatan terakhir mengenai AI tempatan, terutamanya pada komputer riba: menggunakan GPU pada kapasiti penuh menggunakan 100% tenaga sistem. Jangkakan kipas anda akan berjalan, dan anda mungkin juga menghabiskan bateri – walaupun semasa komputer riba anda dipasang! Semua AI generatif sangat intensif kuasa, jadi jika anda menggunakan model AI generatif secara kerap pada mesin anda, jangan harapkan mesin anda melakukan banyak perkara lain pada masa yang sama melainkan anda mempunyai mesin yang hebat.

Ingat sebab utama untuk menggunakan model tempatan: kos, privasi, fleksibiliti, kelestarian, dan kebolehpercayaan. Prestasi terkini BUKAN salah satu sebab untuk menggunakannya, jadi jika anda menangani tugas yang sangat kompleks yang menuntut prestasi terkini, gunakan model perintis besar sebaliknya.

Harap panduan ini memberi anda tempat permulaan yang hebat untuk AI generatif yang berjalan secara tempatan. Jika anda mahukan lawatan yang lebih strategik, tonton ceramah ini yang saya berikan di persidangan MAICON 2024 mengenai model terbuka dan AI tempatan. Walaupun terdapat banyak perubahan teknikal dan taktikal, strategi sebahagian besarnya kekal sama.

En Qué Estoy Pensando: Cómo Empezar con Modelos de IA Locales

Después de que una publicación se hiciera viral en LinkedIn, supongo que es hora de escribir cómo empezar con modelos de IA locales. Proporcionaré dos advertencias en esta edición del boletín. Primero, será inherentemente más técnico de lo que probablemente está acostumbrado con la IA generativa. Usted y yo estamos acostumbrados a abrir una ventana del navegador, iniciar sesión en las herramientas de IA de nuestra elección y hacer las cosas. Nunca tenemos que pensar en la plomería y la infraestructura que hacen posibles esas herramientas.

Si se siente incómodo o no puede (debido a las políticas de TI de la empresa, por ejemplo) hacer estas cosas más técnicas, entonces siéntase libre de simplemente relajarse y leer, o saltarse esta edición por completo.

La segunda advertencia es sobre el lenguaje. Hay muchos términos confusos en este espacio, así que deberíamos establecer algunas definiciones. Uso varios términos diferentes que son algo intercambiables, así que pongamos las cartas sobre la mesa:

• IA Local: modelos de IA generativa que usted ejecuta en su propio hardware, desde su teléfono hasta sus propios centros de datos locales (on-premise). Cualquier entorno donde tenga control total de la máquina en la que se ejecuta el modelo de IA es IA local.
• Modelo abierto/modelo de pesos abiertos: modelos de IA generativa que son distribuidos gratuitamente en línea por los creadores de modelos. Estos modelos le permiten ejecutarlos en cualquier lugar, y no tiene que pagar al creador del modelo para usarlo. Algunas personas erróneamente los llamarán modelos de código abierto o IA de código abierto, pero casi ningún creador de modelos distribuye el conjunto de datos de entrenamiento en sí mismo que se necesitaría para calificar como verdaderamente de código abierto.

Técnicamente, NO son lo mismo. La IA Local es local para usted y su red. Los modelos abiertos pueden ejecutarse en cualquier lugar. Por ejemplo, puede ejecutar modelos abiertos en IBM WatsonX.ai, la nube segura de IA generativa de IBM. No es local en absoluto. Usted no tiene control sobre la máquina en la que se está ejecutando. Pero para muchas organizaciones, especialmente aquellas que operan dentro de la nube de IBM y necesitan la tecnología de gobernanza de IBM, es un gran lugar para ejecutar modelos de pesos abiertos.

Probablemente deberíamos hablar de POR QUÉ querría hacer esto, cuando servicios como ChatGPT son tan convenientes. Hay cinco razones por las que podría querer usar modelos de IA locales en lugar de un servicio de IA SaaS:

• Privacidad: cuando ejecuta modelos en su hardware localmente, ningún dato sale de su sistema. Tiene tanta privacidad y seguridad como su propia máquina. Este es un GRAN atractivo para cualquiera que trabaje con datos sensibles.
• Costo: cuando ejecuta modelos en su hardware localmente, el costo es su costo operativo (generalmente electricidad). Esto es súper importante para cosas como I+D (Investigación y Desarrollo) donde podría estar haciendo toneladas de llamadas API a un modelo como parte de su proceso de desarrollo. Usando un proveedor de nube, esto podría acumular facturas enormes antes de que siquiera tenga un producto para mostrar o vender. Usar modelos locales reduce ese costo sustancialmente – y podría ser lo suficientemente exitoso como para justificar el uso de un modelo local incluso en producción.
• Sostenibilidad: cuanta menos energía use para operar la IA, más sostenible es. Sí, claramente hay economías de escala cuando los proveedores tienen poder de cómputo masivo y concentrado, pero dado que todos buscan absorber tanta electricidad como sea posible, no es exagerado imaginar que la IA consume increíblemente muchos recursos. Usar modelos locales puede reducir ese consumo de energía si se hace bien.
• Control: cuando ejecuta modelos localmente, tiene control total sobre cómo se configuran, mucho más de lo que cualquier servicio en la nube le permitiría. Esta es un arma de doble filo; puede configurar mal un modelo hasta el punto de que se vuelva no funcional – pero si hay cosas específicas que quiere que haga un modelo, el acceso a esos controles adicionales puede ser útil.
• Confiabilidad: los modelos de IA locales se ejecutan en su máquina. Una vez que los descarga, son suyos. Si OpenAI cerrara mañana, ChatGPT desaparecería, pero su IA local continuaría funcionando mientras lo hiciera su computadora.

Con estos puntos en mente, profundicemos en el proceso de CÓMO configurar estas cosas. Si está viendo la versión en video de este boletín, verá algunos de estos ejemplos con mayor detalle. Necesitamos hablar sobre hardware, modelos, software, configuración y uso, en ese orden.

Parte 1: Hardware

Para ejecutar modelos de IA generativa en su máquina, necesita recursos suficientes. Los modelos de IA generativa típicamente necesitan muchísima memoria para funcionar bien. Su computadora tiene dos tipos de memoria que son importantes: memoria regular de la computadora (RAM) y memoria gráfica (VRAM o RAM de video). Para que la IA generativa funcione bien, la VRAM es la más importante – y la variable más salvaje.

Las laptops para gaming de hoy en día suelen venir con 12-16 GB de VRAM, aunque algunas plataformas de gaming de alta gama vienen con más. Las Macs de hoy son un caso aparte – las Macs desde 2019 (las Macs de la serie M con nombres como M1, M2, M3, M4) tienen memoria compartida, lo que significa que la RAM regular y la VRAM son lo mismo. Hay un gran fondo común que la computadora comparte automáticamente.

Esto importa mucho porque en las PCs, a menudo necesitará software que pueda cargar modelos de IA tanto en su VRAM como en su RAM, y cuando un modelo de IA se ejecuta en la RAM regular, es l-e-n-t-o.

El mensaje básico aquí es simple: si está comprando/usando PCs, obtenga tanta VRAM como pueda permitirse. Si está comprando/usando Macs, obtenga tanta memoria como pueda permitirse. Más siempre es mejor.

Su computadora, en algún lugar de su configuración (ha pasado un buen rato desde que usé una PC, pero supongo que el Administrador de Tareas o las Preferencias del Sistema lo llevarán a donde quiere ir, y probablemente pueda pedirle a Windows Copilot que simplemente le diga) le indicará cuánta memoria tiene disponible. Si recuerdo correctamente, tanto las Macs como las PCs tienen una aplicación de Monitor de Actividad que le informa el estado actual de su computadora.

Encuentre el estado de su memoria, cierre todas sus aplicaciones abiertas y tome nota de cuánta memoria de cada tipo tiene.

Por ejemplo, en mi MacBook, esto es lo que veo sin nada más ejecutándose:

Puede ver que tengo alrededor de 110 GB de memoria total disponible. Necesitaremos esta información en breve.

Parte 2: Modelos

Una vez que hemos determinado cuánta memoria tenemos disponible en general, podemos empezar a ‘buscar’ modelos. Digo buscar porque necesitamos encontrar modelos de pesos abiertos que se ajusten a nuestras necesidades. En el repositorio de modelos Hugging Face, hay más de 1.6 millones de modelos diferentes para elegir. Por supuesto, muchos de ellos están diseñados específicamente para tareas concretas, así que nos centraremos en algunas grandes familias de modelos que actualmente tienen un alto rendimiento.

Las tres familias que recomiendo para el usuario empresarial promedio son:

• Google Gemma
• Meta Llama
• Mistral

En cada familia, hay diferentes tamaños de modelos. Verá esto listado en el nombre del modelo, el número de parámetros que contiene el modelo. Los parámetros indican cuánto conocimiento e información contiene un modelo. Por ejemplo, verá cosas como Google Gemma 3 1B, 4B, 12B, 27B, etc. Esos números indican 1 mil millones de parámetros, 4 mil millones de parámetros, etc.

En términos generales, más es mejor PERO hay una limitación: cuanto más grande es un modelo en parámetros, más memoria necesita para funcionar bien. Si elige un modelo que es más grande que la memoria que tiene disponible, literalmente bloqueará su computadora al consumir toda la memoria y detendrá por completo toda su computadora.

¿La contrapartida con los modelos de parámetros más pequeños? Los parámetros son conocimiento. Cuantos menos parámetros, menos capaz es el modelo. Un modelo como Google Gemma 1B es coherente pero alucinará casi todo, inventando cosas porque casi no tiene conocimiento de fondo. Un modelo como Google Gemma 27B será mucho más fluido y conocedor.

Es importante decir que los modelos abiertos en general que puede ejecutar en una laptop serán mucho menos conocedores que los grandes modelos de frontera a los que estamos acostumbrados. Se estima que el modelo GPT-4o de ChatGPT tiene billones de parámetros, al igual que Google Gemini. Hablaremos más sobre las implicaciones de esto en un momento.

Antes de profundizar en la elección de modelos específicos, debemos hablar sobre un aspecto muy confuso de la selección de un modelo: la cuantización.

Los creadores de modelos lanzan sus modelos en el formato de mayor precisión posible. Cuando interactuamos con esas versiones de los modelos, realizan tareas a su nivel de precisión más alto, pero consumen mucha memoria. Devoran la memoria como locos y se ejecutan bastante lentamente.

La comunidad de pesos abiertos a menudo toma un modelo hecho por un creador de modelos y realiza una cuantización en él, que es una especie de compresión. Lo que hace es reducir la precisión del modelo, pero lo hace significativamente más rápido de operar. Podemos profundizar en las matemáticas de la cuantización en otro momento, pero el resumen rápido es que queremos modelos que estén cuantizados a 4, 5 o 6 bits. En términos generales, la cuantización es un equilibrio entre el uso de recursos y la precisión, y la cuantización de 4-6 bits es el punto óptimo para la mayoría de los modelos.

Esto se ve en los nombres de los modelos, como gemma-3-27b-q5_k_l. Este nombre bastante arcano significa el modelo Gemma 3, versión de 27 mil millones de parámetros y cuantización de 5 bits.

Aquí está el resumen rápido que puedo ofrecer sobre la cuantización: en general, use modelos q4 o q5 siempre que pueda.

Luego elija un modelo basado en sus parámetros y su memoria. Mi regla general es: tome el número de parámetros, duplíquelo, y esa es la RAM que necesitará para que el modelo sea útil. Defino útil como un modelo que opera a una velocidad razonable (unos 15 tokens/segundo) y tiene una ventana de contexto suficientemente grande (unos 64K) para ser útil para la mayoría de las tareas comunes.

Por ejemplo, suponga que eligió Google Gemma 3 4B, con una cuantización q4 o q5. 4 * 2 = 8, por lo que necesitará 8 GB de VRAM disponibles para ejecutarlo bien. (Sí, para la gente más técnica, hay un montón de matices aquí, pero estamos tratando de empezar. Duplicar la memoria de esta manera tiene en cuenta una ventana de contexto generosa y la caché clave/valor.)

Entonces, de la parte 1, ¿cuál es su VRAM disponible? Si tiene una tarjeta gráfica de 16 GB, puede ejecutar de forma segura un modelo 8B bien, o cualquier cosa por debajo de ese número. Podría ejecutar Google Gemma 3 4B fácilmente. Sí, técnicamente puede ejecutar Google Gemma 3 12B, pero será tan lento y con una ventana de contexto tan pequeña (la memoria a corto plazo disponible en un chat) que no será útil.

En mi Mac, tengo unos 110 GB de memoria disponible, lo que significa que puedo ejecutar cualquier tamaño de modelo Gemma hasta su tamaño máximo de 27B y que sea utilizable y rápido. Podría ejecutar modelos de hasta 55 mil millones de parámetros en mi configuración actual.

Cuando visitamos el repositorio de Hugging Face para modelos, o miramos los catálogos de modelos en las interfaces, esto ahora nos da una línea base para elegir modelos.

Podemos mirar los modelos por familia y parámetros sin tener que tener en cuenta también la cuantización más allá de lo básico, al menos para empezar.

Pasemos al software.

Parte 3: Software

Ahora que tenemos una comprensión de qué modelos podemos ejecutar, necesitamos obtener el software necesario para ejecutarlos. Nadie ejecuta un modelo de IA directamente; los modelos de IA son esencialmente bases de datos gigantescas de estadísticas en su núcleo. Para hacer uso de un modelo, necesitamos una interfaz a su alrededor. Esto es similar a los autos; nadie conduce por la carretera sentado en un bloque de motor. El bloque del motor está incrustado en el propio automóvil, y aunque el bloque del motor es crítico – un automóvil no puede ir a ninguna parte sin un motor – tampoco es útil el motor sin el automóvil.

Para la persona promedio que quiere empezar con modelos de IA locales, querrá elegir una interfaz que también tenga incorporado el servidor backend. Piense en las interfaces de IA como piensa en la Web, con dos partes principales, un servidor y un cliente.

Cuando navega por la web, su cliente – el navegador web, como Safari o Chrome o Brave – sale e interactúa con el servidor web de otra persona que contiene el sitio web. Empresas como WP Engine tienen servidores – muchos de ellos, hardware grande – que sirven software como WordPress y, en última instancia, sitios web como el sitio web de Trust Insights. Necesita ambos: un cliente sin servidor es inútil, y viceversa.

Los modelos de IA funcionan de manera algo similar. Hay un servidor que sirve el modelo y un cliente que interactúa con él. Cuando visita ChatGPT o Claude o Gemini por navegador o aplicación, está utilizando el cliente para hablar con los servidores de IA que se ejecutan en esas grandes empresas tecnológicas.

En el espacio de los modelos de IA locales, existen paquetes de software que agrupan ambos, que son tanto cliente como servidor. Esto es lo que queremos usar para empezar con la IA local en el nivel más básico.

Hay dos paquetes de software que recomiendo para la persona promedio que no está súper ansiosa por configurar servidores: AnythingLLM y LM Studio. Ambos son gratuitos; las principales diferencias radican en la funcionalidad. AnythingLLM tiene MUCHAS cosas incorporadas, como gestión de documentos, reconocimiento de voz, etc. Intenta hacer mucho y en su mayor parte lo logra; también tiene la interfaz básica estilo chat que todos conocemos y usamos.

LM Studio proporciona la misma interfaz de chat familiar también, pero intenta ser un servidor más robusto además de un cliente. Es especialmente bueno para las Macs actuales de la serie M, ya que admite el estándar de IA MLX de Apple. Una versión MLX de un modelo se ejecuta entre un 5 y un 8% más rápido que un modelo no MLX.

¿Cómo decidir entre los dos? Si planea usar agentes, APIs o desarrollar código contra su IA local, sugiero encarecidamente LM Studio (o si tiene una Mac). Si planea simplemente usarlo como consumidor final, de la misma manera que usa ChatGPT o Gemini hoy, entonces AnythingLLM sería una buena opción.

Estas son aplicaciones estándar que se ejecutan en su computadora, así que instálelas como instalaría cualquier otro software.

Parte 4: Configuración

Así como una pieza de software recién instalada como Microsoft Word necesita alguna configuración o personalización para que sea útil para su caso de uso específico, también el software de IA necesita alguna configuración para que sea útil.

Primero tenemos que decidir qué modelo usar. Hay un montón de opciones. Una de las peculiaridades de los modelos abiertos es que, con tantos de ellos, se sabe que diferentes modelos son buenos en diferentes tareas, y hay muchos modelos especializados que están diseñados o ajustados específicamente para un tipo de tarea. Esto contrasta con una herramienta como Gemini, Claude o ChatGPT que intentan, y en gran medida logran, ser buenos en muchos tipos diferentes de tareas.

Veamos algunas familias de modelos diferentes y en qué son buenos.

• Google Gemma 3: Gemma 3 hace un muy buen trabajo siguiendo instrucciones, especialmente las versiones 12B y 27B. Si tiene tareas donde seguir instrucciones (como instrucciones paso a paso, flujos de trabajo, etc.) es importante, Gemma 3 le servirá bien. Gemma puede escribir pero tiende a ser un poco escueto.
• Meta Llama 3.3: Aunque Llama 4 está en el mercado, es demasiado grande para la mayoría del hardware de consumo. Llama 3.3 es la versión actual que puede ejecutarse en hardware de consumo. Llama 3.3 es una opción decente para la escritura de no ficción.
• Mistral Small: La familia Mistral sobresale en el trabajo multilingüe y la escritura. Es muy capaz, especialmente la versión Small actual, Small 3 24B, un modelo de 24 mil millones de parámetros. Recuerde que querrá tener 48 GB de VRAM/memoria para sacarle un uso sólido.
• DeepCoder: Si está usando IA generativa específicamente para escribir código, DeepCoder es un modelo fantástico para la codificación, especialmente para los primeros borradores.

Una vez que elija un modelo que sea de un tamaño apropiado para la memoria y los recursos que tiene, descárguelo en la interfaz de la aplicación.

En la ventana principal del chat o en la configuración, dependiendo de la aplicación que esté utilizando, querrá tomarse unos momentos para familiarizarse con las funciones y posiblemente jugar con algunas configuraciones. Una de las configuraciones más útiles de conocer es un parámetro llamado temperatura. Verá esto en la configuración del modelo.

¿Qué hace la temperatura? Fundamentalmente, la temperatura controla el nivel de aleatoriedad en las respuestas del modelo. Una temperatura baja significa menos aleatoriedad. Una temperatura más alta significa más aleatoriedad.

¿Por qué querría jugar con esto? Algunas tareas son muy deterministas; no quiere que el modelo se vuelva demasiado creativo. Por ejemplo, si le pidiera a un modelo que clasificara un texto en un conjunto de categorías definidas, establecería una temperatura baja, como 0.5, para evitar que arbitrariamente proponga nuevas categorías.

Otras tareas son más probabilísticas, como la escritura creativa. Establezca la temperatura demasiado baja y obtendrá una generación increíblemente robótica. Una temperatura entre 0.7 y 1.0 tenderá a producir una escritura más creativa al permitirle al modelo más libertad para ser creativo.

Para aquellas personas acostumbradas a una interfaz como ChatGPT, esto podría parecer inusual. Detrás de escena, servicios como ChatGPT tienen exactamente las mismas configuraciones y controles; es solo que esos modelos de usuario final suelen ser establecidos por el proveedor y el consumidor promedio no tiene la capacidad de controlarlos o cambiarlos.

Bien, entonces tiene su software instalado. Tiene su modelo descargado e instalado. Tiene su configuración ajustada. Finalmente está listo para comenzar a usar la IA local.

Parte 5: Uso

Finalmente, llegamos a la parte buena, ¿verdad? Bueno, la parte buena es sorprendentemente aburrida: es como cualquier otro modelo de lenguaje grande de IA generativa que haya usado. Hay un par de giros que son importantes de conocer cuando se trata de modelos abiertos e IA local.

¿Recuerda cómo hablamos sobre el recuento de parámetros, cómo cuantos más parámetros tiene un modelo, mejor tiende a funcionar? Esto es relevante tanto para seguir instrucciones (es decir, hacer lo que le dice que haga en sus prompts) como para el conocimiento. Más parámetros significan más conocimiento codificado.

Pero excepto por modelos realmente muy grandes como Llama 3.1 405B (405 mil millones de parámetros), DeepSeek (671 mil millones de parámetros) y un puñado de otros, la mayoría de los modelos locales tendrán efectivamente menos de 50 mil millones de parámetros. A esa escala, los modelos tendrán algo de conocimiento, pero los riesgos de alucinación son muy altos.

Lo que eso significa es que usted tiene que aportar más datos. Aquí hay un ejemplo simple. Si le pregunta a un modelo pequeño como Gemma 3 4B quién es el CEO de Trust Insights, dará una respuesta sin sentido. Si le proporciona la respuesta, la recitará perfectamente.

Ahora, podría decir (con bastante razón) que si tenemos que proporcionar la respuesta, ¿cuál es el punto? Bueno, ahora entramos en los casos de uso de la IA generativa (sobre los cuales puede aprender más en mi nuevo curso, Casos de Uso de IA Generativa para Marketers) y en qué son buenos los modelos más pequeños.

• Extracción: sacar datos de otros datos
• Clasificación: organizar datos
• Resumen: convertir datos grandes en datos pequeños
• Reescritura: transformar datos de una forma a otra
• Síntesis: tomar datos pequeños y agregarlos en datos grandes
• Respuesta a Preguntas: responder preguntas sobre sus datos o en general
• Generación: crear nuevos datos

Cuando se trata de IA local, los primeros 5 casos de uso aquí son donde realmente brilla. Dados los datos, incluso modelos muy pequeños como Gemma 3 4B pueden hacer un trabajo muy capaz, y también serán rápidos como un rayo al respecto.

Donde fallarán es en los casos de uso 6 y 7, cuando les pedimos a los modelos que creen nuevos datos. Por ejemplo, pedirle a Gemma 3 una recomendación de restaurante en su área sin proporcionar ningún dato no va a ir bien. Simplemente no tiene suficiente conocimiento. Pídale mientras le proporciona un documento JSON grande de restaurantes y sus ofertas, y lo hará bien.

Lo mismo ocurre con la generación. Pídale que escriba, por ejemplo, una publicación de blog sobre marketing B2B sin ningún dato de fondo y se le ocurrirá contenido genérico y mediocre. Simplemente no hay suficiente conocimiento en ningún dominio para que cree contenido realmente único y convincente, especialmente una vez que está por debajo de unos 10 mil millones de parámetros. Déle su archivo de boletines y podcasts como almacén de datos, y es probable que lo haga mucho mejor generando algo.

Donde estos modelos brillan es en tareas repetitivas, especialmente si puede automatizarlas. ¿Recuerda el boletín de la semana pasada sobre n8n? Un modelo de IA local representará un ahorro de costos enorme si puede conectar un flujo de trabajo para usarlo en lugar de un servicio basado en la nube.

Parte 6: Conclusión

Nos centramos principalmente en el cómo en esta edición del boletín, y si tiene el hardware y herramientas como LM Studio o AnythingLLM, está bien posicionado para comenzar a utilizar modelos de IA locales.

Una advertencia final sobre la IA local, especialmente en laptops: usar la GPU a toda máquina consume el 100% de la energía del sistema. Espere que sus ventiladores funcionen, ¡e incluso podría agotar la batería mientras su laptop está enchufada! Toda la IA generativa es increíblemente intensiva en energía, así que si está usando modelos de IA generativa intensamente en su máquina, no espere que su máquina haga muchas otras cosas al mismo tiempo a menos que tenga una máquina bestial.

Recuerde las razones clave para usar modelos locales: costo, privacidad, flexibilidad, sostenibilidad y confiabilidad. El rendimiento de vanguardia NO es una de las razones para usarlos, así que si está abordando una tarea muy compleja que exige un rendimiento de vanguardia, use un modelo de frontera grande en su lugar.

Espero que esta guía le brinde un excelente punto de partida para la IA generativa ejecutándose localmente. Si desea un recorrido más estratégico, vea esta charla que di en la conferencia MAICON 2024 sobre modelos abiertos e IA local. Aunque ha habido muchos cambios técnicos y tácticos, la estrategia sigue siendo en gran medida la misma.
