MiniMax M3: Frontier coding, 1M-token context, and native multimodal model

MiniMax M3：前沿编码、100万token上下文与原生多模态一体模型

MiniMax released M3 as an open-source unified model with coding, agent, and native multimodal capabilities, supporting a 1M-token context window and using MiniMax Sparse Attention to cut per-token compute at 1M context to 1/20 of its predecessor, with over 9x faster prefill and over 15x faster decoding.

Why it matters: HKR-H/K/R all pass: MiniMax M3 has a 1M-token context hook, MSA with a claimed 20x cost cut, and open-source China-model resonance. Single official-source release keeps it in the 78–84 band, not P1.
