“My bet is that Pretty soon we're going to move into more of the alpha zero style of training where you have a more traditional LM that's trained on all of the internet. But then the way to train the next generation of it would be to give it a reinforcement learning environment where, ah, it's generating a lot of problems and doing, like, self-play, where solving these problems, getting feedback on them, and doing it in this, like, massively parallel way. I think this is how we're going to get the next generation software agents. It's not going to be trained on human code, because, like you said, there's not going to be human code, and so we have to solve this.”
