On June 1, 2026, Chinese LLM company MiniMax officially released its new generation general model MiniMax M3 via its official blog. It is the first domestic model to simultaneously possess three core capabilities: cutting-edge coding ability, 1M ultra-long context, and native multimodality, and is currently the only open-source model in the world with such performance. On the authoritative programming benchmark SWE-Bench Pro, M3 scored 59.0%, surpassing GPT-5.5 and Gemini 3.1 Pro and approaching Claude Opus 4.7, with code generation quality reaching "production-ready" standards. The company also announced that model weights and technical reports will be open-sourced within 10 days.
