MiniMax Releases Open-Source M3 with Coding, Long-Context, and Multimodal Capabilities

MiniMax发布开源模型M3，集成编码、长上下文与多模态三大能力

MiniMax released the open-source M3 model with coding, a 1M-token context window, and native multimodal support; M3 scores 59.0% on SWE-Bench Pro, 83.5% on BrowseComp, and costs about one-twelfth per token versus GPT-5.5.

Why it matters: HKR-H/K/R all pass: M3 has open source, 1M context, multimodal support, and 59.0% on SWE-Bench Pro. A single X post without official docs or third-party tests keeps it in the 78–84 band.
