arXiv:2607.05394v1 Announce Type: cross Abstract: Reinforcement learning with verifiable rewards (RLVR) is a powerful recipe for improving language-model reasoning, but it is expensive to repeat on every new strong model because the target model must generate many rollouts during training. As models scale, post-training itself becomes a bottleneck. We study a weak-to-strong alternative: run RL on a smaller model where rollouts are cheaper, then reuse what that RL run learned to improve a stronger target model. Directly distilling the post-RL weak teacher is not enough, because the teacher's fi
The increasing computational demands of training powerful language models via RLVR necessitates more efficient methods like weak-to-strong generalization, which this paper directly addresses.
This research could significantly reduce the cost and time associated with improving large language models, enabling faster iteration and broader application of advanced AI capabilities.
The previous bottleneck of costly repeated RL training on every new strong model could be circumvented, allowing for more agile development and deployment of sophisticated AI.
