MiniMax Launches M3 Large Model: Pioneering the MSA Architecture and Supporting 1M Context, Fully Open-Source to Compete with Overseas Flagships
MiniMax Xiyu Technology launched its next-generation cutting-edge large model M3 on June 1, 2026. This is the first domestic open-source model integrating top-tier programming, 1M ultra-long context, and native multi-modal capabilities, competing with overseas closed-source flagships. To address the context expansion bottleneck in complex intelligent agent tasks, M3 independently developed the sparse attention architecture (MSA), achieving more precise KV block division and operator-level optimization. The computational speed is more than four times faster than similar open-source solutions, with a significant reduction in computation per token at 1M context.
