On the Direction of RLVR Updates for LLM Reasoning: Identification and Exploitation

ICLR 2026poster

Reinforcement learning with verifiable rewards (RLVR) has substantially improved the reasoning capabilities of large language models. While existing analyses identify that RLVR-induced changes are sparse, they primarily focus on the **magnitude** of these updates, largely overlooking their **direct…
