MiroMind-M1: Advancing Open-Source Mathematical Reasoning via Context-Aware Multi-Stage Reinforcement Learning

MiroMind AI has introduced the MiroMind-M1 series, an open-source pipeline designed to advance mathematical reasoning in large language models (LLMs) by providing transparency and reproducibility that proprietary models like GPT-4o and Claude Sonnet 4 lack. Built on the Qwen-2.5 backbone, MiroMind-M1 employs a two-stage training processsupervised fine-tuning on 719,000 curated math problems and reinforcement learning with verifiable rewards on 62,000 challenging problemsto significantly enhance multi-step reasoning capabilities. This development sets a new standard for open-source
