  1. 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.
  2. 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.
