M3.1 Flash 权重可下载，428B 总参/23B 激活、1M 上下文、支持 vLLM/SGLang/TokenSpeed；非商用免费，商用需署名，年收入超 2000 万美元需书面授权。
🇨🇳 MiniMax’s M3.1 Flash weights are actually out now. You can download them, not just try the model through an API. • Around 428B total parameters, with 23B active per token • Up to 1 million tokens of context • Takes text, images and video, and produces text • Serving support listed for vLLM, SGLang and TokenSpeed The license needs a closer look, though. Non-commercial use is free. Commercial users need to send a one-time notice and include attribution. If the relevant products or services generate over $20M in annual revenue, written approval is required first. And “23B active” doesn’t make this a laptop model. You still need serious hardware to run the full thing. A large Chinese model you can host yourself, with the weights available and the licensing strings attached.
