arXiv:2605.23384v1 Announce Type: cross Abstract: Recent RL methods have substantially improved the reasoning abilities of LLMs. Existing reward designs mainly follow two paradigms: (1) Reinforcement learning with verifiable rewards (RLVR) derives outcome signals from executable checks or ground-truth answers, but provides limited guidance for intermediate reasoning behaviors. (2) Rubrics-as-reward (RaR) goes beyond final-answer checking by using natural-language rubrics to assess reasoning quality and task compliance, but often requires instance-specific rubrics and substantial design effort.
The continuous drive to enhance LLM capabilities, particularly in complex reasoning tasks, necessitates more sophisticated reinforcement learning techniques beyond simple outcome-based rewards.
Improving LLM reasoning through 'metacognition as reward' could unlock more robust, general-purpose AI agents capable of complex tasks with less human oversight, accelerating automation.
Current methods for reinforcing LLM reasoning involve either verifiable outcomes or subjective rubrics; this 'metacognition as reward' approach offers a middle ground for guiding intermediate reasoning steps more effectively.
