Dmitri Dolgov: belief

Transcript context

…Does the simulator ever run locally? No, it doesn't. However, what I think is interesting, in a way, the way the decoder works, the way the model works. If you think about the generative task in the simulator of creating those realistic worlds and how other people behave, how cars, pedestrians, cyclists, and the task that you have to solve on the car in real-time, there is this fundamental shared capability of understanding how these objects relate to each other and predicting what they might do in the future if you are running on car and then generating, some sampling, those probabilistic behaviors in the simulator. It's different models, but this is why the shared foundation model is able to power both. Similarly, if you think about the critic, the job of the critic is to find interesting events and then be opinionated about what's good behavior and what's bad behavior. Similar fundamental understanding. If you're running inference on the car, you still have to figure out which of the multiple hypotheses of these future worlds you want to take action to steer towards. Okay, and these are all downstream of the same foundation model?…
