新研究表明两阶段 LLM 训练优于联合方法

一项新的研究论文提出了一种名为 OPD-then-RL 的两阶段方法,用于提高大型语言模型的推理能力。该方法包括先进行策略内蒸馏 (OPD),然后进行可验证奖励强化学习 (RLVR),其性能始终优于在单个步骤中组合这些信号的方法。研究表明,OPD 首先扩展了模型对教师支持解决方案的理解,然后 RL 对这些解决方案进行优化。该论文还提供了一个实际指导方针,指出 OPD 验证分数是确定何时过渡到 RL 的关键指标,并且 OPD 比监督微调 (SFT) 更有效地作为 RL 的起点。 AI

影响 这项研究可能带来更有效的 LLM 训练技术,提高推理任务的性能。

    Sequential Beats Joint: On the Interplay between On-Policy Distillation and RLVR

    arXiv:2609.04108v1 Announce Type: cross Abstract: Reinforcement learning with verifiable rewards (RLVR) and on-policy distillation (OPD) have emerged as two dominant methods for post-training reasoning LLMs. Prior work uses OPD's dense token-level supervision to complement the sp…
