New Agon RL framework uses competing models to grade reasoning

Researchers have introduced Agon, a novel reinforcement learning framework that uses two competing models to grade each other's reasoning processes. This competitive approach trains models to think more effectively by implicitly judging their reasoning during training, rather than solely rewarding the final answer. Agon has demonstrated significant improvements, doubling the pass@1 rate on the DeepMath dataset when compared to standard GRPO training and outperforming a Mixture-of-Agents approach. AI

IMPACT This competitive RL approach could lead to more robust and capable reasoning models by directly training for better thinking processes.
