So right now we're instrumenting with our own product. So we're instrumenting groups of inferences and individual inferences, which means we can then create charts that show how often they fail, why they fail, how often we need to retry to get good answers.

It's like, all right, compute all those embeddings. That's more work upfront because you have to go through your database of all of these things and you got to commit like that engineering work, but it's like you validate with the general model because it's just easy.

It can be really scary. And that's another sort of mental model of framing we've been thinking around is we find LLMs right now are most useful either when you come from, either when you have a narrow input space and a broad output space, because you can be very, you know exactly what format of data, what kind of data is gonna be passed in.

I always try to raise the awareness of this, that Copilot I think did a really interesting metric or North Star, which was how much code is kept or retained by the user.

Now, when we talk about large behavioral models or like actually embedding events, there are many, many trillions of those. And yeah, Postgres probably doesn't work there.

I think I've talked about this on the podcast, but this idea of like just-in-time UIs, you know, like each type of user wants to interact in a different way.

And we hit a bunch of problems there with LLMs hallucinating, losing context, even within the context windows, not really sort of recalling everything within the context window. So we sort of did a bunch of experimentation and realized if we split this down to seven different questions, so instead of saying, generate me a chart and a query for this one question, let's split that into lots of sub queries, like what kinds of events should I use?

Because the LLMs can do a lot more of the reasoning, but we can make sure that the context we're providing is much more specific and generally much better by using the traditional ML models.

At the same time, I think the future of AI applications and doing really cool things with it will be in the data, partially because like, you know, ChatGPT has done such a huge advance, right?

I don't know if I can share the actual customer, but actually from before the LLM days, where they literally generated the versions of the copy themselves, and they made their product basically adapt, you know, multi-arm bandit style of like, hey, here's all these different variations, like just go figure out the best one.

Sure, yeah, happy to speak to that. So, you know, if we think about the fundamental thing that our customers of Amplitude try to do, it's they want to look at their product data and they want to figure out how do I make my product better?

I think that would make everyone's lives a lot easier if you could somehow ask behavioral questions of data without having to instrument.

I don't know what the constraints on our lightning round, but I think maybe creativity is the best word where it's, you know, with the image generation stuff, text generation, you know, one thing that still blows my mind, I used to be a competitive like math guy and like there's this international math Olympiad problem in one of the papers and it solves it.

We do have some smaller, not even fine-tuned, some smaller models that we've sort of borrowed from Hugging Face that we run internally for more specific tasks. And that's often sort of selecting specific values before we pass it to a general model right now, just because the general models are much easier to communicate with and they understand most of the words we use.
