Moonshot AI’s Kimi K3.1 Pro Highspeed is now available on Amazon Bedrock

AWS Machine Learning says Moonshot AI’s Kimi K3.1 Pro Highspeed is now available on Amazon Bedrock. The model is part of Moonshot AI’s K3.1 series and uses the same 3T-class open-weight architecture and 1-million-token context window as Kimi K3, with substantially more post-training compute. Moonshot AI says that extra training targets long-horizon agentic work and fewer factual errors, and that the model produces output tokens at 2–3 times the speed of Kimi K3.1 Pro.
