Process Reinforcement through Implicit Rewards (2025 · 151 citations)
Reinforcement learning for LLM reasoning usually relies on one verifiable reward at the end of each response.
The Entropy Mechanism of Reinforcement Learning for Reasoning Language Models (2025 · 101 citations)
Reinforcement learning with verifiable rewards is now a main way to improve LLM reasoning, but scaling it hits a recurring problem. Without explicit regularization, policy entropy falls to almost zero within the first training steps. The model becomes overconfident, stops exploring and its validation accuracy stalls.
