Mind Readings: DeepSeek Week Part 1 – Why Is Everyone Talking About DeepSeek?

This week, we're gonna talk about Deep Seek. We're gonna go deep on Deep Seek, the if you pardon the puns, and why everyone's talking about it, what makes it good, and specifically which versions, uh, if any, you should be using and whether it's safe, all the questions that you have about uh this very, very interesting family of models that's been around for some time, but people are just figuring out now that it exists. So let's dig in. In today's episode, we're gonna talk about why is everyone talking about Deep Seek? What is this thing?

Deep Seek is a Chinese company. It's a Chinese technology company that, like many other companies around the world, makes artificial intelligence models, AI models. Uh they make language models. So they are their versions, they currently have two major flagship versions, uh V3, which is their regular chat version. The equivalent in uh OpenAI would be OpenAI uh GPT 4.0, which is the stock model that people use with chat GPT.

Uh another equivalent would be uh something like Google's Gemini uh Pro. And then they have R1. R1 is their reasoning model that thinks things through and is great for complex tasks. Again, in uh in the the Western branded uh AI models, uh OpenAI's 01 model is a reasoning model. Google's Gemini 2 Flash thinking, it's a mouthful, uh model, is a a reasoning model.

These are some of the the the bigger, best better well known uh reasoning models. Why is why is this particular uh model uh the in particular R1 uh getting everyone's attention? It comes down to two things quality and price. In the released versions of Deep Seek V3 and uh and R1 the quality is almost as good as or better than Western counterparts so let me bring up this is uh let me I need to reset my screen here let's go ahead and do that there we go uh we see here the quality versus price the analysis this is from uh artificial analysis dot AI and we see here there's openAI's 01 the quality score the c the average quality score it achieves on most benchmarks is 90.3 and the cost uh per million tokens is 26 per million tokens then over here is 01 mini its quality is 83.6 and its cost is five dollars and twenty five cents clawed sonnet 3.5 the most current version of Claude has a quality score of 80 and a cost of $6 per per uh set of tokens uh i need I think I need to turn on Google's Gemini I don't have Gemini let's turn on Gemini Pro and Flash so we can see them we see Gemini Pro here at 80.4 is on neck and neck with uh Claude and cost of $2.19 cents for Pro for Gemini Flash uh that is 13 cents per million tokens quality of 74 Meta's Lama 3.37 a score of 74 in quality 67 cents per million tokens open AI's GPT 4.0, the stock model. Quality score of 73.1 and a cost of $4.38 cents then we get to deep seek.

Deep seek reasoning Model, R1, $2.88 cents uh no I'm sorry, $2 per million tokens. 88.8 score. So it is on par with 01. But look at that cost difference. $26, $2, uh $2.

So this is more than 10 times expensive than R1 for about the same quality. If you look at Deep Seek V3, 90 cents per million tokens. Quality score of 79.1. Compare that to open AI's, $4.38. So we're talking, what, almost five times more expensive for higher quality.

This is why everyone was talking about uh Deep Seek because its models are incredibly powerful and stupid cheap in their API. And rightfully, a lot of people are saying, what happened there? Well, the folks at Deep Seek uh did uh essentially told everyone they said here's what we did. And there's a paper out uh it's called Deep Seek R1 that explains the process that they used to make these models. You can download this on their website.

It is a fairly uh technical paper. The secret sauce for Deep Seek is twofold. Number one, uh they used uh they're using a an architecture that's very efficient. The architecture is called mixture of experts. Google's Gemini is also a mixture of exercise model, which is different than what's called a dense model, uh, like chat GPT's, uh GPT four.

Um, so it is a a very, very sprightly and efficient model. And the way that they built this is wildly different than the way other model makers have made models in the past. And it comes down to two things reinforcement learning and what's called uh GRPO, according to the paper. GRPR is group relative policy optimization, which is a reinforcement learning algorithm that uh does not have a separate model for the reinforcement learning that's built right into the main model. So this dramatically cuts down training costs.

Here's here's a way to think about how these two things, these two models are different, like open AIs and and the Western models versus what DeepSeq did. If we think of them as kitchens in O1 or Gemini or Claude, think of the training the chefs there in very classical fashion. You you go through culinary school and you spend years on the uh you know being an apprentice and then a sous chef and and chopping up things for you know and fetching coffee for the the executive chef. And eventually, after a lot of time and a lot of money and a lot of effort, you end up with uh a uh a Michelin-starred chef, right? That would be the way that traditional models work.

Deep seek used reinforcement learning from the beginning rather than supervised fine-tuning. So in the in the restaurant analogy, um, they gave the chefs basic skills and then said, guess what? You're gonna learn how to cook the hard way. Uh, well, we would think of it the hard way. You're just gonna do stuff and we're gonna correct you along the way.

And so it's a much more, I guess you call it intuitive way to learn how to cook, whereas you don't you're not you know digesting huge textbooks of how to cook. Instead, you're learning through experience how to cook. What they did was in terms of producing the model, this creates a much more capable model because it spends all of its time learning what to do and what not to do through experience rather than sets of rules. Uh so the this this approach is very, very different. And that's what makes it so good and what makes it so cheap.

By doing it this way, they dramatically cut down on the compute costs, which is important because one of the things that the the government of China, the People's Republic of China, um, has against it is export restrictions. A lot of the top-tier AI chips that uh are produced in countries like America and and other places in the world that are are are super technical economies, like Taiwan, for example. Um, China can't buy 'em. China can't get a hold of them. Um and as a result, Chinese AI labs have to figure out how to make the most of the hardware that they have.

And so through using um this this group resource policy optimization, they're essentially saying we we're gonna figure out how to to make this model incredibly inexpensive to operate and lightweight because we don't have a choice. We don't have the biggest, beefiest, nicest hardware. It's again, imagine back to the kitchens. You have one kitchen that is uh all Viking appliances and it's you know super high end, and then you have one kitchen that is maybe not the the high-end appliances, the appliances in the kitchen still work, they still're still good. Then it's not like you know that you're you're cooking at you know with stuff made out of uh random parts found on the side of the road.

It's still good, it's just it's like Hamilton Beach, right? It's the the the cheaper equipment. When you learn to cook in an environment like that, you learn to you learn to make the most of what you have. And that's why Deep Seek is is so efficient and effective. And the other thing that has everyone talking quite a bit, is that Deep Seek just gave away the model.

They put it up on Hugging Face, which is where pretty much everyone who's a model maker puts their stuff when they want to give it away. And the rest of the world can take it and run with it, which is pretty amazing that they can do that. It is it has caused such a stir in Silicon Valley that if you go into apps like Blind, which is the sort of the the tech water cooler uh gossip, pretty much all of Silicon Valley is losing their crap because Deep Seek has come out with a high performance model that meets state of the art, uh that is way cheaper and they're giving it away. So if you wanted to, if you had the hardware to support it, you could run it yourself and it would do well. They also demonstrated their techniques, which I thought was very clever, um, on existing models.

So if you were to go into uh their their repository on Hugging Face, you'll find not only do they have their model up there, but then they've taken uh other models like Quen and Llama and tuned them using their their processes to create these distilled models that, in the case of Llama 70B, have chart topping scores. So they took an already good model and turned it into a world-class model with very, very little resources. So that's that's pretty darn amazing. And again, everyone in the uh the Western tech community is kind of losing it because it kind of invalidates a lot of the the hype and the tech bros uh and the tech oligarchs talking about how much they need all this energy and all this money and they need a $500 billion project. And and this this Chinese firm is like, no, you don't.

Here, state of the art. We did it uh on the equivalent of driving uh Volvo. And and you're saying you need a Bugatti, you don't need Bugatti to get to get uh world class performance. You can do it in a Volvo. And that's what's happened.

So this is part one on why everyone is talking about this thing. In the next part, we're gonna look at the different versions and see uh what's available. So stay tuned for that.
