And so we had one person who was running teams at Neuro, we had one person who was at Waymo, someone who had their own YC tools startup for machine learning, and we were really excited to build something together. And this was around late 2023, so about a year and a half ago at this point. And yeah, when we got started, I mean I think there were a couple of things that we felt really strongly about and one was that reinforcement learning was really working and was going to be the next big paradigm shift in capabilities. Back then it was the initial ChatGPT launch in 2022, and those models were, to first order were what we would call imitation learning in AI, right, which is basically you have the model read all the texts that you can find on the internet and then train it to talk like somebody on the internet would talk. Right. And there are kind of obviously a lot more details on top of that, but that's kind of the first order pass of what was really done.
