MiniMax M3 Just Beat GPT-5.5 on Coding. It's Also Free to Run.
A Shanghai-based lab released an open-weight model that outperforms GPT-5.5 and Gemini 3.1 Pro on SWE-bench Pro — with a 1-million-token context window and API pricing at 5–10% of the cost. The frontier just got a lot more open.
MiniMax M3 scores 59% on SWE-bench Pro — beating GPT-5.5 and Gemini 3.1 Pro on the hardest coding benchmark available. It has a 1-million-token context window, multimodal capabilities, and API pricing at $0.60 per million input tokens. The open-source gap with frontier models is closing faster than most developers realise.
