A Stitch in Time Saves Nine: Proactive Self-Refinement for Language Models

ICLR 2026poster

Recent advances in self-refinement have demonstrated significant potential for improving the outputs of large language models (LLMs) through iterative refinement. However, most existing self-refinement methods rely on a reactive process with a fixed number of iterations, making it difficult to deter…
