Here's the latest talk I gave, last friday at the USC Information Sciences Institute. It's a slightly more technical version of the RL talks I've been giving, focusing on the different ways we (and the community is experimenting with RL for reasoning). It includes a bunch of discussion on GRPO expanding on my previous video.
