GAR in RL Training: How Groupwise Advantage Redistribution Assigns Credit to Winners
tokenbender · x · 2026-09-22
In an ongoing thread on RL training, the author breaks down GAR (Groupwise Advantage Redistribution): it handles credit assignment among winners in a group, since passing candidates vary in quality — some mediocre, some clean, some excellent — and GAR weights learning credit accordingly. The author also teases a follow-up post covering training infrastructure and RL streaming. This is a mid-thread fragment with incomplete context.
