Welcome to Foundational Principles of Generative AI Part 11. This is about efficiency today. Foundation principle number 11: choose the smallest model that still gets the job done. This is especially important when you are concerned about sustainability.
Generally speaking, reasoning models are the smartest models there are, but reasoning models consume far more resources than non-reasoning models. Generally, we advocate for consumers. We’re just using ChatGPT or Gemini. Feel free to use a reasoning model. You’ll get good results out of it. When you start putting things into production, use the smallest model possible that still gets the job done because otherwise your costs are going to be out of control.
When a reasoning model thinks things out, for example, Gemini or ChatGPT’s O3 model, there could be as much as three times as much text in the thinking part as the actual result. And when that happens, all of that text costs compute, costs electricity, costs fresh water, etc.
If you can use a reasoning model to figure out a process that makes a very reliable, efficient prompt, then future runs of that to generate the same or similar quality result, you can do at a much lower cost, cost much less energy, use far fewer resources. A lot of the tasks that we ask generative AI to do you don’t need the biggest, best, flashiest, most powerful model to do. No one needs a huge mixture of experts, 671 billion parameter model to summarize your emails or to summarize a conference call. Nobody needs to.
That’s like taking a Harrier to the grocery store. Yes, you can do that, but that’s a terrible use. Take a bicycle to the grocery store. Don’t take a fighter jet. You don’t need to use that much firepower just to get a task done.
This is going to become a major consideration once AI companies start charging what it actually costs to operate generative AI. Because almost all these companies are losing money, or like OpenAI is burning billions of dollars a year in investor money to keep their services available. Same for Anthropic. Companies like Google or Meta have a lot of spare compute anyway, and they have a lot of buffer to be able to offer these services, but they’re still not making money on it. You can’t spend money at a loss forever. And so when the bill comes due, if you are only using the biggest, best, flashiest models for everything possible, you’re going to pay a lot more for generative AI.
Whereas if you have small, medium, and large offerings for generative AI, small being something you run on your laptop, medium being something that runs in your company’s infrastructure, large being a foundation model on a big service, you will find that you can shift a lot of the tasks over time to the smaller models because they keep getting smarter too. Today, for example, the Quen3 30 billion parameter mixture of experts model, called Quen330B-A3B, which is terribly named, is really smart.
It’s really fast, and it runs on a decent MacBook. If you have a MacBook that has like 32 or 64 gig of RAM, you can run this model on it pretty easily, which means you don’t have to rely on any part of the cloud. It is a small model. It does the job well, and you don’t need to do something bigger.
So, principle 11 is use the smallest model that still gets the job done, especially in production. That’s going to do it for this episode. Thanks for tuning in. Talk to you on the next one.
