GSPO Algorithm Breakthrough: Stabilizing Large Model Reinforcement Learning

A Breakthrough in Large Language Model Training: How GSPO Algorithm Solves Reinforcement Learning Stability Issues? Introduction: Why Reinforcement Learning is Key to Upgrading Large Models? In recent years, top-tier large language models (LLMs) like Qwen3 have achieved breakthroughs in complex tasks such as mathematical reasoning and programming. Reinforcement Learning (RL) technology has been instrumental in this progress. By allowing models to receive feedback after generating answers and optimize their strategies, RL has helped LLMs transition from “knowledge memorization” to “deep reasoning.” However, as models scale beyond billions of parameters, training stability issues have become increasingly prominent.
