The model uses a sparse attention architecture that reduces computation for 1 million tokens to one-twentieth of the previous generation, with speed improvements of over 9 times in prefilling and over 15 times in decoding. On the SWE Bench Pro coding benchmark, M3 surpassed GPT-5.5 and Gemini 3.1 Pro; on SVG Bench, it outperformed Claude Opus 4.7. MiniMax stated the model will be distributed as an open model within 10 days of the announcement.\u003c/p\u003e\u003cp\u003eAPI pricing is set at $0.60 per million input tokens, $2.40 per million output tokens, and $0.12 per million cache reads for up to 512,000 tokens, with higher rates for longer contexts.
