Moonshot AI has published open weights for Kimi K3.1 Pro on Hugging Face, the first model in its K3.1 series. The model is natively multimodal and agent-oriented, with 2.8 trillion total parameters, 104 billion active parameters, and roughly 1 million tokens of context; the weights are released in MXFP4 quantization. Moonshot also offers an API through platform.kimi.ai under the kimi-k3.1-pro identifier, compatible with OpenAI and Anthropic interfaces. The supplied material does not include verified benchmark results.

Moonshot AI is reportedly negotiating to rent more than 8,000 Nvidia Blackwell GPUs from European neocloud data centers, mainly for inference and some training, according to CNBC&\x27;s account of unnamed sources. The arrangement would use remote access to work around U.S. export controls that bar Blackwell imports into China; the report says Moonshot may have to pay a 30%–50% higher prepayment than non-Chinese buyers. The White House said in July that the company had obtained Blackwell chips through a Thailand facility. The reported plan has not been confirmed by the companies involved.
