TextualRL framework boosts LLM agent accuracy by 24% on GPT-5.5

Researchers have developed TextualRL, a novel reinforcement learning framework designed to enhance LLM agents' ability to adapt through context updates. This method treats groups of rollouts from the same task as the unit for policy critique, enabling more effective comparison of successful and failed attempts. TextualRL refines context updates by reviewing proposals against pooled evidence across tasks, leading to significant performance improvements. When applied to GPT-5.5 and Qwen3.8-27B, TextualRL boosted test accuracy by 24.4 and 15.3 percentage points, respectively. AI

IMPACT This framework could enable LLM agents to adapt more effectively to tasks by refining their contextual understanding, potentially leading to improved performance in complex applications.

    TextualRL: Textual Reinforcement Learning for Context Management

    LLM agents can adapt to task feedback by revising the textual context that guides their behavior, without changing their model parameters. However, turning execution rewards into reusable context updates is challenging: individual trajectories offer limited comparative evidence a…
