Mind Readings: How to Benchmark and Evaluate Generative AI Models, Part 1 of 4

In today’s episode, are you confused by all the hype around new generative AI models and unsure how to assess them? You’ll discover the common benchmarks used to evaluate AI like GPT-4.5 and Gemini, and why these might not be enough for real-world marketing. We’ll explore the limitations of these public benchmarks and set the stage for building your own custom evaluations in the next episodes. Tune in to learn how to make sense of AI performance and make informed decisions for your business.

In this series, we’re going to talk about benchmarking generative AI models. Every time a new model is announced, something like GPT 4.5 from OpenAI, or Google Gemini 2, or Anthropic Clawed Sonnet 3.7, a lot of folks, myself included, post very excitedly about, hey, here’s what’s new. Check out this new model. It’s cool. It can do these things. And that’s great if you’re an AI enthusiast, which I am. That’s less helpful if you’re the average marketer going, I don’t even know, is this good? Is this better than what I’ve got? Should I be using this? How would you know?

So today, in this four-part series, we’re going to be going through what the current benchmarks are, why you would want to evaluate with your own benchmarks, and then look at the steps that you would take to do that evaluation. We’re going to do a lot of hands-on stuff in parts two through four, so stick around for that. Those will be in separate episodes.

Today, let’s talk about the benchmarks that exist out there that are pretty commonplace. I’m going to flip over here to, this is a website called Artificial Analysis, one of many, that talks about benchmarks. And what they look at is they look at a bunch of public tests that are given to AI models to see if they’re capable of performing those tasks.

So let’s scroll down here to the intelligence evaluations. We have MMLU. We have GPQA Diamond, general question and answering. Humanities last exam, live code bench for coding, sci code for coding, human eval for coding, math 500 for being able to do math, aim 2024 for math, and multilingual index.

Now, here’s how these work. There’s a set of test questions, and then every model is given a chance to do these tests. In many cases, companies like Artificial Analysis will actually do the tests themselves. So they will not take the results from the individual labs because, let’s face it, every lab wants to say, oh, I’m the best, you know, or scored on this, and we want to independently verify those things.

So for the average, slightly more technical user who wants to do comparisons, you can drop down the menu here on any of these tests and say, I want to compare these different models. I want to compare GPT 4.5. I want to compare with Lama 3.2 and so on and so forth. And you can see a very large selection of models. There are 125 different models that you could choose from. And generally speaking, what we’re looking for is who’s in sort of the top five, right? When you look at these different benchmarks, what models score in the top five?

So MMLU, if I click on this here, it says click for more information. Information, nothing happens. We have DeepSeek R1, which is DeepSeek reasoning model. OpenAI’s 01, Claude Sonnet 3.7. We have, who is that? Google Gemini Pro 2.0 Pro. And Claude—oh, there are two versions of Claude. Claude thinking, which is the extended thinking, and then regular Claude. So for MMLU Pro, and you can Google this, right? So if you go and look at what this is, this is the massive, multitasking language understanding data set. That’s a mouthful. And you can see the top models for that particular—it’s over a general purpose reasoning and knowledge. It’s a good indicator of a model’s general fluency.

GPQA diamond, again, pop that into your Google, and you can see graduate Google-proof Q&A benchmark. So being able to answer questions intelligently. They have GROC 3. Now, it says for GROC 3, that is provided by the company. They have not had a chance to independently test it yet. 03, Claude, looks like regular GROC 3, then 01, and so on and so forth. And we go down further, and we see Humanity’s last exam. Again, let’s put that in here. This is an AGI test that people can submit questions to and get a sense of how smart a model is. And you can see the scores for this are much lower, right? So in these other tests, 84% is sort of the high watermark, 80% the high watermark there. Humanity’s last exam is 12%. A lot of models struggle with this particular exam. So you have 03, Claude, DeepSeek, 01, and Gemini.

For live code bench, again, this is one of three coding benchmarks. Let’s go ahead and just Google this real quick. Live Code Bench, contamination free evaluation of language models for code. Now, contamination free is important because a lot of language models have been able to see questions in the past. And it’s kind of like, you know, reading the test in advance, reading the answers in advance. These tools, or benchmarks like this, allow you to hold out those questions. We’re going to come back to that. That’s a really important point in just a little while. We see here, O3Mini, O1, DeepSeek, and then the Claudes. And for the sci coding, the Claudes are in that lead there, human eval coding. This comes from, I believe, L.M. Arena. And this is people’s preferences that they evaluate and say this model did a better job. And again, the scores there are really, really high of Claude and Deep Seek in that lead there.

On the ability to do math, again, in the high 99 percentage is there. Another math exam, O3, and then you have Claude and Deep Seek, and then multilingual, O1, Deep Seek, V3, Lama 3.3.

So these evaluations are a good way to look at apples to apples, particularly when you want to look at a lot of different models. They are good for when you want to even get a sense of who’s the competitive set, who are the top 10 models, who are the top labs. So OpenAI, Anthropic, DeepSeek, XAI, Google, to get a sense of it, yeah, this is who broadly we probably want to use. And this is a really important thing to remember. When you look at a lot of these benchmarks, there’s not a huge difference on a lot of them from in the top five. The top five are all so closely spaced together that if you’re a customer, say, you’re using chat GPT, and you see Anthropic comes out with a new model, like, oh, should I switch? Is it better? When you look at the numbers, [they are] not that much better.

So from a perspective of, you know, do I need to hop from tool to tool? As long as it’s in the top five on the majority of categories, you’re probably going to see improvements in the next round of testing or the next model that comes out from your favorite provider that is probably going to be okay. The field is accelerating so fast that a lagging model today could be a huge winner tomorrow. We saw this happen with the Lama family. Lama 2 is like, yeah, okay, Lama 3 is pretty darn good. We saw this happen with Gemini. When Google first got into the generative AI space, they had BARD. BARD sucked. Gemini took some time. It took a bunch of tries to get going, but it is really—it is a state-of-the-art foundation model today.

Now, those are the synthetic benchmarks, and they’re good. However, they are not representative of the use cases for most real people in the real world. There isn’t a “write me a blog post about B2B marketing” benchmark in there. And so what you might want to think about would be building your own benchmarks, building your own testing suite for the ability to evaluate a different model. So when something new comes out, you’re like, oh, is it substantially better? Let’s go find out.

To build your own benchmark, you’re going to need two types of data. You’re going to need public data, and you’re going to need holdout data. And what we mean by that is using stuff that’s been seen in public, right? And we’ll talk about what those benchmarks might be. And then stuff that’s never been seen before. So internal documents, perhaps, that you have, that have never been trained in an AI before as a way to test real-world cases.

So that’s sort of what benchmarks are. Again, the purpose is to understand, when a big amount of fanfare comes in, is one model better than another? And the two types of benchmarks are the public ones, like Artificial Analysis, and then your own.

So in the next part, we’re going to talk about what does it look like to build your own benchmark. So stay tuned for that. They’ll talk to you on the next one.
