Moonshot posts Kimi K3.1 Pro open weights: 2.8T-parameter MoE with a 1M-token context
The agentic text-and-image model (104B active, MXFP4 weights) is now public in 96 safetensors shards, with vLLM, SGLang and TokenSpeed recipes and an OpenAI/Anthropic-compatible API as kimi-k3.1-pro. Its MIT-style license allows commercial use but requires a separate deal for model-as-a-service businesses above $20M yearly revenue.
