Survey maps rubric-guided RL for better LLM alignment

A new survey paper introduces a framework for rubric-guided reinforcement learning (RL) to improve the alignment of large language models (LLMs). This approach uses structured, interpretable rubrics instead of simple scalar rewards to guide LLM behavior. The paper categorizes existing methods along a prior-posterior axis, including constitutional AI and instance-specific rubrics, and discusses challenges like linguistic reward hacking and semantic drift that affect alignment reliability.
