Papers
- OpenRLHF: An Easy-to-use, Scalable and High-performance RLHF Framework (2024 · 140 citations)
Training LLMs with RLHF and RLVR, especially with PPO, is dominated by text generation. The authors say this phase can take more than 90% of runtime when models produce long chain-of-thought outputs. Existing tools also force a trade-off. TRL, DeepSpeed-Chat and ColossalChat are approachable but weak at inference… - REINFORCE++: Stabilizing Critic-Free Policy Optimization with Global Advantage Normalization (2025 · 104 citations)
Critic-free reinforcement learning methods for aligning LLMs, such as GRPO and RLOO, avoid the memory and compute cost of PPO's value network. - ProRL: Prolonged Reinforcement Learning Expands Reasoning Boundaries in Large Language Models (2025 · 58 citations)
Researchers disagree on whether RL with verifiable rewards teaches LLMs new reasoning or only makes already-reachable answers more likely.
