Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, Lisa writes in, “I just saw a thing on LinkedIn about Klarna, the software company, kicking 1,200 SaaS providers to the curb, including Salesforce. And when you read the details, it says, Klarna, CEO, Sebastian Simiatowski—gosh, it’s a Polish name—casually dropped that the bombshell on an earnings call, that they’ve basically built their own. They use generative AI to build their own CRM, and so they’re dropping Salesforce.”

So, what’s my take on it?

Here’s the thing. The ongoing equation for software companies and SaaS in particular is build versus buy. That is always the balances. Which do we do? Do we build? Do we buy?

When you buy it, you pay money, and in return, you don’t have to make the software. You don’t have to maintain the software. You don’t have to provide updates to the software. You don’t have to do anything to the software. It just happens for you.

Now, there’s upsides to that. It’s lower maintenance. If you don’t have the technical talent in-house, you don’t have to maintain it. You have to fix bugs. You don’t have to worry about infrastructure. You don’t have to worry about security. All that should be taken care of by somebody else in exchange for lots of money. That’s a good model for a lot of people.

When you build it, you don’t pay money to other people except maybe some infrastructure costs. You instead pay money to a developer. You pay money to a QA person, a product manager. You…is a product that you have to maintain internally. You’ve got to patch the bugs. You’ve got to keep it secure. You got to do all these things to make this thing run and stay running and be highly available and all that stuff.

Here’s what’s different now in the world of generative AI. The equation is always, do we spend time and effort, or do we spend money? When you look at the time and effort in the era of generative AI, particular with tools like Ader or Klein or Cursor, any of these AI-enabled development tools, suddenly the scale starts to tilt because now you don’t need 5 or 10 or 15 developers or QA people to run an app. You might need one or two or maybe three, and it becomes a lot cheaper.

On the flip side, one of the things with SaaS companies is you’re kind of stuck with them. That’s what SaaS companies are always talking about. How do we make our product more sticky? How do we make it harder for people to leave? How do we make it harder for people to change to a competitor? What can we offer in our product that makes it very difficult for someone to ever exit? That’s why for years, we’ve always said, if whatever vendor you’re working for, if there isn’t an export button that exports to like CSV files, don’t use that vendor because they’re trying to lock you in.

When generative AI dramatically reduces development costs and QA costs and dramatically reduces the effort it takes to make changes or updates to a system and knows the best practices for securing a system, yeah, it suddenly starts to look more appealing. Here’s the thing, here’s the part that SaaS vendors don’t want to talk about at all: nobody has a moat. There is no moat anymore. There is no moat that prevents someone else from developing a competitor. Even if you’ve got your proprietary interface and all this stuff, the reality is CRM or marketing automation is an idea. You cannot copyright ideas.

So, someone could take the idea, like, “Hey, I want a CRM that does this, this, this, this, and this. And I also want to do this that no vendor offers. I want to do this that no vendor offers,” and so on and so forth. You hand it to generative AI with the help of a skilled developer—please don’t do this without the help of a skilled developer, it will just go badly—make the thing. It will be exactly what you want. You have to still maintain it. You have to still work on the infrastructure. You have to still provide the security, the high availability, but the cost to create the thing is much, much lower.

Back in the early 2000s, I worked to the financial services company. I was reasonably good at PHP, reasonably good at MySQL, and we built a custom CRM. It took me six months to build this thing with the web interface and the database and all the custom fields and stuff. Eventually we ended up hiring two or three more developers just to advance the thing because we hit a limit of my level of skill. Six months.

When I think back to the product requirements of what was in version one that took me six months to build, with generative AI, I could probably build that in about a day, maybe two days, because I know exactly what the layout is. I know exactly the database layout is. I know what the requirements are for what it had to do. Yeah, it would take 8 to 12 hours instead of six months to make the same product.

When build is 50%, 60%, 80% cheaper, by starts to look like a bad deal. Yes, there is the whole, let somebody else handle the mess for me, but more and more, generative AI is going to change that equation. If you are a SaaS company, assume that product is not the advantage anymore. Product can be very easily replicated.

So, what else do you have that would differentiate you in an age when everybody can make your product? Is it the service? Is there unique data that your platform has access to that other people don’t have and that they couldn’t easily replicate? Is there a relationship? Do you have…does your software come with an account manager who knows the industry and can provide that expert-level, serve strategic advice? Is there downstream outputs that you can provide or upstream outputs that you can provide that, again, are very hard for generative AI to replicate?

If you are a product-first company and you’re doing as much as you can to reduce your costs on support and stuff like that using AI, well, guess what? You are making it easier and easier for an AI system to reproduce your company, your crown jewel, the thing that makes you money, and it puts you at substantial risk, substantial risk.

So, to answer Lisa’s question, what’s my take? My take is that SaaS companies have no moat when it comes to product and that the build versus buy equation is tilting dramatically in favor of build for product itself. What will allow a SaaS company to remain in business is all the stuff that isn’t product. If you are cutting costs everywhere with AI, then you are making yourself obsolete very, very quickly.

It is incumbent upon every company that makes software as a product to say, what is our non-product advantage? And it is incumbent upon every company that uses software to sit down in question, should we build this, particularly, should we build this tailored to our industry? Should we build this tailored to our company?

Think about something like Libra Office, the open-source office productivity suite, that is the open-source movement’s answer to Microsoft Word and Excel and all that stuff. It is very good. It has been very good for a very long time. Companies who are looking to save on licensing costs will use Libra Office. It’s cross-compatible with all major document formats. It’s very good. The same reason people use Google Docs.

What would it look like? Because it’s open-source to take the Libra Office source code with detailed prompts from how you use office software and a coding environment like Ader or Klein or Cursor and say, remove all the stuff that we never use. And here’s a whole bunch of things that the legal profession uses. Let’s remove these features from the code base and make a slimmed-down, streamlined version of the software that is tailored for the work that we do. Or there’s this thing. I wish this software did that nobody’s software does. How do we build this into a fork of this for ourselves?

This is one of the reasons why I think open-source software is so important for every company to understand what’s out there, what is freely available, what is things that you can modify, because in the past, yeah, you would have had to devote a dozen developers to tuning and maintaining open-source software for your company. Now it’s like one developer and generative AI. Suddenly that equation is very different.

So, that’s my answer to Lisa’s question. If you are a company that uses software, you should be looking and reevaluating build versus buy. If you’re a company that makes software, you should be thinking about how customers might do an end run around you and then focusing on what are the advantages that you bring that are not software, even though you’re a software company.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, let’s talk about briefly and succinctly, how do you explain agents, particularly AI agents, but agents in general, succinctly. How do you explain it to somebody? How do you explain it to yourself?

Let’s think about and go back to our product market fit levels. There’s three levels of product market fit. There’s services and products that are done by you. There are things that are done with you and things that are done for you.

You see this in food. A recipe is done by you. You buy all the ingredients. You have the appliances. You’ve got the tools and stuff like that. Presumably you have the skills. You do all the cooking. The recipe tells you what to do, but you’ve got to provide everything.

A meal kit is done with you. You get the big box in the mail and you unpack it and throw away the freezer packs and stuff like that. And it’s half cooked, and you do some of the cooking. You assemble some of it. A box of cake mix, most of the cake is done. You just got to add like an egg and some water and turn it into a cake. So that’s a kit. It’s done with you.

And of course, a meal out is done for you. You do none of the cooking. You show up at the restaurant and you do nothing. It’s just you, you’re there only to receive the output.

When we think about generative AI, when we think about agents, it’s kind of the same. A workflow is done by you. You might have a series of prompts and some data. So, you open up Chat GPT, and you copy and paste the first prompt and you wait for it to respond, and you copy and paste the next prompt and so on and so forth. You’re doing all the work. You’ve brought all the data. It’s like the appliance almost. You have to do everything, but you get the outcome and you’re happy with the outcome. That’s great. Very manually labor, labor-intensive.

An automation is done with you. Maybe you have like a custom GPT that you’ve built that where there’s a long list of system instructions. You bring some stuff, but it already has some stuff built, and it just kind of half does the thing with you. You have to start and stop it, but it’s less work for you.

An agent is done for you. You do nothing. The agent just does the thing. Maybe you’ve got an AI agent in Chat GPT that scans the news every morning and sends you an email: here’s the six things that you need to know that are happening in the news today. You don’t do anything. You just show up and like up there’s an email from my agent today saying here’s the six things I need to pay attention to. It’s all done for you. It’s all done for you. You have to do…you’re not there. You’re not part of the process.

The reason agents are being so hyped right now is that the promise to the makers of the agents and the tech companies, there’s a lot more money. A meal out costs more than a meal kit. A meal kit costs more than a recipe. An agent costs more than an automation and an automation costs more than a workflow. It’s more compute-intensive. It uses a lot more resources.

So, there’s a couple important things to keep in mind here. Number one, every great AI agent grows from an automation, which grows from a workflow. If you’re not sure about whether a task should be an agentic AI task or not, does it work in a workflow? If it doesn’t work with you copy and pasting it and doesn’t work reliably in Chat GPT, it ain’t going to work as an agent. You never want to start building an agent without first establishing in a workflow that the thing actually works.

Second thing to be aware of, again, there’s a lot of hype about AI agents. Look carefully. Is it really an agent that you’re being sold or is it an automation? To be clear, there is nothing wrong with automations, nothing wrong with automations. They’re great unless someone has decided to charge you agent prices for something that isn’t an AI agent. A vendor hoping to slap “agent” on the label and Sharpie an extra zero on the cost, and it’s really an automation.

Agents do it all without you there. If you have to show up and do something, it’s not an agent. It is an automation. If someone is charging you a premium for it because they’re calling it an agent and it’s really not, get out that correction fluid and erase that extra zero on the price tag. That’s going to do it for today’s episode.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

All you have to do is ask.

In today’s episode, let’s talk about the art of being productive with generative AI. The art of being productive with generative AI is the art of asking great questions. The art of asking great questions is rooted in the very Buddhist perspective of self-awareness. I’m putting your ego aside.

Here’s an example. The other day, my friend Robin Summers asked me to look at a paper and a statistical analysis. Just to be clear, I did very, very, really in statistics in college. I had a professor who was really good at statistics. He was a really good researcher. He couldn’t teach it very well. Thank goodness he graded on a curve because I outright failed the class. Like my actual grade was 37. That’s how badly I did statistics.

So, I know beyond any reasonable doubt that when it comes to statistics, AI is way smarter than I am. When I looked at Robbins data, I knew there was more juice that we could squeeze from it. She did a statistical analysis, and I looked at it and was like, there’s more we could do here, but I don’t know what. I didn’t know how to think about it. I didn’t have the techniques in my head. So, what we did was I cleaned the data. I prepped it, denormalized it, put it into a table, and then I handed it to Anthropic’s Claude 3.7 sonnet.

Now, what I didn’t say to Claude was improve this analysis. Why? Because that’s assuming the original methods were correct, and I didn’t know if that was true. I had a feeling, but I didn’t know.

So, I asked. I used this prompt exactly: “Next with the tabular data in the original paper and the information in the supplementary pieces, what algorithms or transformations could we apply to it to garner additional insights, the absence of new data? What statistical or data science methods might shed additional light and strengthen the original paper? Assume we have no additional data beyond what has already been provided.”

Claude thought about it, gave me a nice long list. There were nine different statistical methods and candidates. It’s just things that we could do.

So, I followed up and I said, “Which approach would be the most insightful for this data set, given the limitations? Rank the approach as you listed from most insightful to least insightful.”

And it did. It went through and said, “Here’s the technique that we think, that I think works the best.” It said, “You should do survival analysis with Cox proportional hazards.” I have heard those terms, Cox proportional hazards. I don’t know what they mean because again, failed statistics. I can Google it, of course, but I said, it’s probably not the best use of my time to learn statistics in the moment.

So instead, I said to Claude, “The data I uploaded, write a Python script to perform the survival analysis using Cox proportional hazards, plus the usual block of knowledge I include anytime I ask AI to write code.” It’s a 21-page list of best practices for Python coding stuff like PEP8 compliance or dry, which stands for “don’t repeat yourself” in code. It’s all these coding principles that I put together. Anytime I have AI write code, I give it that because, in addition to being terrible at statistics, I’m not a great coder, but I do know how to assemble a requirements document or a best practices document so that AI can be a much better coder than me.

So, I did that. Claude spit out the Python script and then I ran it. Then you might be saying, well, generative AI can analyze data. Generative AI can’t do math. Never ask it to do math. When it does math, it either does two things: it guesses, which is almost always a disaster, or behind the scenes it writes code to execute to then do the math, which is a tremendous waste of resources.

So instead, I said, write me the code and I’ll run it. So, it spit out the code. I ran the code. It spit out some visualizations, a final product. It processed the data and turned it into…

I then uploaded the image, the charts and graphs that made back to Claude and said, “Now here’s the final results. Interpret it. Tell me what this means.”

And it did. It said, “Hey, there’s the statistical effect that you were doing with just plain averages. When you do a Cox proportional hazards survival analysis, the effect is like 4X what the original method was.”

That’s pretty cool. That’s a very solid analysis that revealed some pretty useful facts. I did not bring useful knowledge to the party this time, and I knew it. I knew it. I’m not a great coder, terrible statistician. So I had to put my ego aside and say, “You know what, Claude, you take the wheel.”

And it did. In much of the task, it was just way better than me. That’s okay because what matters is not who’s the better coder or statistician. What matters is did I get the result? What I did bring was great questions. I brought a not a general knowledge of what needed to happen, breaking down the task myself into individual pieces so that the language model, the AI, could do the parts that it does best: referencing is extensive trained knowledge, writing analysis, writing code.

I did the parts it doesn’t do best, like prepping the data, running the code, processing the math, steering the conversation. You can and should do the same.

Models will continue to evolve and get ever more sophisticated and they’re capable of more and more. But there are some things that today’s generative AI models, because of the architecture of the model itself, it’s unlikely it’s ever going to do well, like math. The Transformers architecture that powers generative AI simply is inappropriate for math, no matter how smart the models get.

So, your value as the human being, as the operator of the AI, is providing why you’re doing the task and then guiding in a way that maximizes its strengths while you handle its weaknesses, either by yourself as a human or with deterministic methods like writing code and doing math.

But if you want to get the most out of AI, that’s how you do it. You let it do the parts it does best. You do the parts that you do best. And together, like peanut butter and jelly, you get the best results possible. That’s going to do it for today’s episode.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

What does a word mean?

One of the things that we fail to recognize about AI, about generative AI and large language models in particular, is that they are all trained on separate training databases. The database that Chat GPT is trained on for some of its models are different than the ones that Grock trained on or the ones that Gemini trained on, and they’re all different. They all have different information in them, which means we may not realize we’re getting separate and different information from each one.

So today, what we want to do is an experiment. The experiment we’re going to run is testing out whether or not there’s a big difference in how these models think about the meaning of a simple word.

So, let’s go ahead and talk through this experiment so that you can see what we’re going to do and then see what the results are. There’ll be a time lapse because no one wants to watch the actual editing part.

So, here’s the prompt that we’re going to use. It says, “Let’s quantify a word. When I say an event never happens, it happens 0% of the time. When I say an event always happens, it happens 100% of the time. When I say an event sometimes happens, what percent of the time does it happen? Return your answer as the integer of the percentage, such as 0 or 100. Return only the integer, nothing else.”

So, what we’ve got here is we’re going to use Elamarina. Elmarina is the head-to-head model comparison tool. It’s called a chatbot arena. We’re going to take that exact prompt.

Let’s go ahead and put it in. Our first two contestants will be GROC 3 and Claude 3.5 Sonnet. Let’s go ahead and hit go. Each model is going to ingest the prompt. Then it’s going to spit out the number. Let’s see what comes up.

Both of them said 50. So I’m going to make a note here. This is GROC 3 and this is Claude Sonnet 3.5, and we are at “sometimes” and we’re going to record 50, 50.

Now what we see is we’ve got a list, a word list of the words and then what we’re going to be testing. So: never, almost never, rarely, frequently, infrequently, sometimes, somewhat often, frequently, often, very often, almost always, and always.

Let’s go ahead and I’m going to just start chewing through the prompts. This will be the time lapse portion of this. We want to test out these different models.

I’m going to choose a couple other popular models. Let’s go ahead and look at Gemini Pro and Gemini. Actually, let’s do GPT. So, you can find GPT Chat GPT. There are the 4-0 latest. So, we’re going to have Gemini 2 Pro. This is GPT 40, and same exact prompt. Let’s see what these two come up with: 50 and 50. Okay, so far we’re in agreement.

Let’s go ahead and do one more set. Let’s look at Meta’s Lama. Actually, let’s do Deepseek, Deepseek V3. And who else we got here on the contestant list? Open AI. Mistral small. There’s Lama 3.1, that Meta’s big flagship model. So, we’re going to Deepseek V3 and Lama 3.105B. Let’s go ahead and see what each of these have to say: 50 and 50.

All right, so now we’ve got a pretty good indicator of how this is going to work. I’m going to go ahead and get started. I’m going to make zero because the prompt says zero. They should all return zero for never. They should always return 100 for always. It would be weird if they didn’t because that’s literally in the prompt. Let’s go ahead and fill out the rest of this tape.

All right, so here’s what we’ve got. We’ve got something really interesting here. Each model, I have color-coded the rows with conditional formatting as to whether, in that row, which model had the highest output. There’s some interesting anomalies in here. In terms of the models that were the most overall conservative in the quantifying word, GPT40 and Gemini 2 Flash, both had scores in the 44.5 range. The most generous was Gemini 2 Pro with a scored in 48 range and Claude Sonnet 3.5.

What’s interesting, if we look here, is Claude Sonnet 3.5 and 37 scored things differently. Sonnet 37 is more conservative in assessing a quantified value to the meaning of these words. Likewise, Gemini 2 Pro is much more generous than Gemini 2 Flash.

One thing I also noticed, and I’m sure you saw it if you slowed down the high-speed portion of the video there, Gemini 2 Flash was trying to do a kind of short-form reasoning all the time. The instructions were clear: return your answer as the integer of the percentage, return only the integer or nothing else. Every single time it was verbose in its responses, so it was not adhering to instructions.

What do we take away from this? What we take away is that words have meanings and those meanings vary per model. If I say something rarely happens, five models say that’s 10% of the time, five models say that’s 5% of the time. If I say something somewhat often happens, you have a mix between 50% of time, GPD4.0 Kamp, or 30% of the time. Gemini Pro says that’s 75% of the time.

So, when we’re writing prompts for generative AI, not only do we have to consider how we prompted in the language we use. If it’s an important prompt, it’s something that words, it’s something that is really vital, you might want to do testing like this to see, A, which model adheres to the definitions you set and B, how do the different models compare. So, if you’re, for example, writing prompts of how to define writing style and there are things like diction or similes or metaphors. And you said, “I use metaphors,” and you said, “I use metaphors somewhat often.” Well, I give that in my prompt to mimic my writing style and GPT40 says that’s 30% of the time, and I go to Gemini and I give the same prompt. Gemini is going to say, well, that’s 75% of the time. Like, okay, that’s a big difference in how these writing styles might work.

So, it’s a good idea to test out those word frequencies to see how does a model think about terms like quantification of numbers. How does a model think about defining certain terms? You could do a test like this for bias and say, “What does this word mean? Absent any other context, what does this word mean to you?” and collect the definitions and compare the definitions to see how does it go.

In fact, maybe we’ll do that in another episode is a one-sentence definition from the model for a series of words, a loaded words and see what they come up with.

But this kind of testing is important. As you can see here, the way I did it, I did it very manually. You could do it programmatically with a Python script. I did it very manually and you could do this too and just follow the exact same procedure, write the prompt, structure it well, copy and paste it in and switch models as you go through it and see what happens.

That’s going to do it for this episode. Thanks for tuning in. I’ll talk to you soon.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In this final part, we’re going to talk about what we do with our model evaluation.

So in part one, we talked about sort of synthetic, the public benchmarks that people use to evaluate generative AI models. In part two, we talked about developing your own benchmark, using your own data and reverse engineering prompts that result in your data. And then part three, we ran the benchmarks. We ran those prompts to see which models came up with the best outcomes and used generative AI to do some scoring with that. And we talked about how to choose that and then different ways you could do those tests. In this part, part four, we got to make a decision.

So let’s take a look at our contestants and see how things netted out from the last time. We did our bake-off, and we found that of the three cutting-edge models that were just released for our tests—the NDA thoroughness, how many pieces the NDA got right, the egg recipe, the SEO report, and fan fiction generation—the winning model was GPT 4.5, with a 391 total score. Just behind it was Claude at 385, and then pretty significantly behind it was Grok 3 at 358. What’s interesting is that you can also see three of the five tests Claude won, [and] two of the five GPT 4.5 won. However, GPT 4.5 scored much more points because Claude really hosed the fan fiction. That was—I think if Claude had scored better on the fan fiction, it would have beaten GPT 4.5. And I would say those two models are very, very close.

So now what? We’ve got our test results. We’ve got our benchmark results. What do we do with this? Well, if you’re talking about making big changes in your technology and your AI technology stack, you have to say, okay, well, how big is the difference? And how and which use cases of these benchmarks matter the most to us. So if I were to look at these use cases, the NDA and contracts and stuff, that’s pretty important. That’s something that we do a lot at work. The SEO report, that’s something we do a lot at work. The egg recipe, we don’t really do that much at work. I threw that in because it’s a fun example, but we don’t really do that at work. And writing fan fiction, we definitely don’t do that work. So in this case, for the work that my company Trust Insights does, Claude is the winner, even though it didn’t score the highest score on the tasks that are the most important to us, it scored the best. If you are writing fan fiction, you don’t really care about NDAs or egg recipes or SEO. So GPT 4.5 would be the model that you would choose based on this evaluation.

That’s how you do this. That’s what you do with this information. You say, I know the categories that are most important to me, and you could add in the public benchmarks as well if you want to add in GPQA or psychoder or whatever the thing is, especially if those tests are tests that are more rigorous that you don’t have the time to do. So like we do a lot of code writing, and so I might want to include some of the coding benchmarks as well. Once you’ve got that, then you make a decision, and you say, all right, we know that for these evaluation cases, this is the technology that does the best for what we need. Let’s go ahead and standardize on that.

And then you have to come up with a testing interval. How often should you retest? Well, the answer is how often you’re going to make changes in the technology? How often you’re going to reevaluate those contracts or the services that you buy? You can’t and you should not be switching tools in production every time a new model comes out. Every time a new shiny object comes out, you don’t want to say, oh, now we have to use this one. You should put it through your evaluations, particularly if you use the more sophisticated evaluation where you have the known good outcome, and you have benchmarks against that, how closely something comes up against that benchmark. That’s a good thing to do. And so it kind of soothes that—it’s just saying, am I missing out? Well, if you have your benchmark tests, when a new shiny object comes out, you run it against the benchmark test, and you say, well, you know what, it’s not that big of a difference. GPT 4.5 just came out like two days after Claude 3.7. The scores are so close and are not different enough to say, yeah, there’s no reason to switch. Claude is perfectly fine. It won on the benchmark tests we care about the most. We’re fine staying where we are. Grok 3 came out. It didn’t score well on any of the benchmarks. So even though its owners and stuff [are] saying it’s the most advanced AML, I don’t know, not for these benchmarks it’s not.

And that’s where you want to go with this. You want to say, what are the benchmarks that matter to me? If you’re an educator, [and] being able to create lesson plans or score and grade exams, none of the public benchmarks do that. But you would absolutely want to do those evaluations for yourself and then say, yeah, this is the technology that works best for the use cases we care about. When you’re about to spend 50 grand or 100 grand on an enterprise contract, you absolutely want to do this testing and be really robust about it. Come up with it. We used one example in each of these four use cases. You might have five or 10 or 20 benchmark pieces because you want to know you’re about to spend $100,000 on something that’s going to fit your needs. And so your testing suite would have many of those examples.

And [shameless plug], my company Trust Insights does this evaluation. We will help you build your benchmark suite and run the tests and use all the best practices so that you can be confident in your decision that you’ve tested generative AI for your specific use cases.

But that’s the process. That’s how you do it. It is time-intensive to build the benchmark, but the good news is that the benchmarks themselves don’t change, right? And the prompts for those benchmarks don’t change all that often. The models may change, but the testing—the benchmarks, by definition, should not change very often, if at all, so that you’re always doing apples to apples with current models and from tests in the past.

I hope you found this four-part series helpful on how do we evaluate generative AI models? How do we know what technology to choose? Again, if you have comments or questions, let them loose in the comments below or hit reply, and I’ll talk to you on the next one. Take care.
