Vision-Language-Action Models

How a vision-language model becomes a robot brain. This lesson covers the VLA recipe: take a pretrained VLM, add an action output, train on robot demonstrations. It walks through RT-2 (actions as tokens, web-knowledge transfer), OpenVLA (an open 7B model), and pi0 (flow-matching action experts), plus cross-embodiment, what generalization buys, and the real limits.
