Self-evolving RL loop on saturated data lifts AIME25 from 22.1 to 32.7 and transfers to Llama-3.1-8B

Follow-up on RL over saturated data: the negative-rollout method still works when saturated and unsaturated data are mixed (+1.8-3.1 pts) and transfers to Llama-3.1-8B. It also enables a self-evolving loop where newly solved prompts join the saturated pool (+443 by step 80) while AIME25 accuracy climbs from 22.1 to 32.7.
