understand-r1-zero

understand-r1-zero is a research project open-sourced by Sea AI Lab (sail-sg) on GitHub, conducting critical research around "understanding R1-Zero-like training." The project examines the two core components of R1-Zero-like training—the base model and reinforcement learning—and reaches several findings: DeepSeek-V3-Base already exhibits the "Aha moment"; the Qwen2.5 base model possesses strong reasoning ability even without using a prompt template, with average benchmark scores improving by about 60% compared to traditional 4-shot prompting; GRPO has a biased optimization problem, and the project proposes a simple correction, Dr. GRPO (GRPO Done Right), which improves token efficiency while maintaining reasoning performance. The project also provides a minimalist R1-Zero training recipe: use Dr. GRPO to perform reinforcement learning fine-tuning on Qwen2.5-Math-7B with the Qwen-Math template on MATH level 3-5 problems. The project released its paper, model, and codebase in March 2025. R1-Zero training is implemented based on the Oat framework, and in July 2025 it received an ICML 2025 AI for Math Workshop Best Paper Honorable Mention.
