  1. DAPO: An Open-Source LLM Reinforcement Learning System at Scale (2025 · 668 citations)
    Recent reasoning LLMs owe much of their strength to large-scale reinforcement learning, but their reports leave out the recipe, so outside groups struggle to match their results.
  2. VAPO: Efficient and Reliable Reinforcement Learning for Advanced Reasoning Tasks (2025 · 68 citations)
    Most RL work on long chain-of-thought reasoning uses critic-free methods such as GRPO and DAPO. These skip the value model and estimate advantages from group rewards. ByteDance Seed's VAPO argues that a learned value model has more potential, because it gives per-token credit assignment and lower-variance estimates…
