This is episode three in our series of foundation principles for generative AI. In this episode, what model should you use?
There are so many different tools. There’s Chat GPT that has like six different models. There’s GPT-4.0, 4.1, 03, 04 Mini, 04 Mini High. In Google Gemini, there’s Gemini 2.0, 2.5, 2.5 Advanced, 2.5 Flash. You get the idea. There’s so many of these tools and so many of these models.
Generally speaking, there’s two fundamental model classes. There’s non-reasoning models like GPT-4.0 or Google Gemini 2.0 Flash. Then there are reasoning models, models like 03, 04, the 04 family in OpenAI, Claude 3.7, Sonnet Extended Thinking, Gemini 2.5, the whole Gemini 2.5 family.
A reasoning model, fundamentally, it does a rough draft of its thought process before it gives you an output. And that tends to increase the quality of the output because the model has a chance to think things through.
These models don’t think like human beings do. They don’t synthesize thoughts silently. They have to say things aloud. So the more that they can talk, the more room they’re allowed to talk, the smarter their answers get.
Generally speaking, consumers—meaning you and me, human beings using these tools in business, B2B or BBC doesn’t matter—the end user, which is called the non-technical user, should be using reasoning models most of the time.
So if you’re saying, I want to write a blog post, or I want to set some strategy, or I want to build an ideal customer profile, generally speaking, you want to be using a reasoning model most of the time.
So that means in OpenAI, the O series, so 03, 04, in Gemini, a 2.5 series, in Claude 3.7 with extended thinking turned on. In DeepSeek, the R family, so R1, R2. Those are generally going to give you the best quality results because they think things through first. They try to figure out what your intent is. They try to figure out what desired output would be best if you didn’t specify it.
In general, reasoning models are good for dealing with the ambiguities that we present when we prompt. So we often will maybe not be as specific as we should be, maybe not as clear as we should be. Using a reasoning model can help eliminate some of that.
The more specific and clear you are in your prompting, the better everything will perform in general. But reasoning models try as best as they can to figure out what your intent is so that for less experienced people with AI, it typically gives better results.
For more experienced people in generative AI, often you will use a reasoning model. Not always, but often you will, because even when you give it a great prompt, if you give it a really solid prompt, it will generally generate better results because it will have more to work with.
So foundation principle number three: in general, use a reasoning model unless you have a clear reason not to.
That’s going to do it for this episode. Talk to you on the next one.
