New Self-Play Algorithm Overcomes LLM Training Plateaus

Researchers have developed a new self-play algorithm called Self-Guided Self-Play (SGS) to address scaling limitations in large language model (LLM) training. Traditional LLM self-play methods often suffer from a "reward hacking" problem where the model generates overly complex problems that hinder learning. SGS introduces a "Guide" role for the LLM, which scores synthetic problems based on their relevance to unsolved targets and their naturalness, preventing the Conjecturer model from collapsing into degenerate problem generation. This approach has shown significant improvements, particularly in formal theorem proving using Lean4, where a 7B parameter model trained with SGS solved more problems than a 671B parameter model without it.
