Kimi K3.1 Pro Highspeed

Kimi K3.1 Pro Highspeed is a post-trained version of Kimi K3 from Moonshot AI, sharing its 3T-class open-weight architecture and 1-million-token context window. Moonshot says the additional post-training targets long-horizon agentic work, fewer factual errors, and coding for game engines, 3D scenes and CAD scripts, and reports 2–3 times the output speed of Kimi K3.1 Pro. The model is now on Amazon Bedrock with tool calling, structured output, configurable reasoning, image input and streaming, plus a Flex tier at half the Standard price.
