AWS Makes Kimi K3.1 Pro Highspeed Available on Amazon Bedrock

Amazon Web Services made Moonshot AI’s Kimi K3.1 Pro Highspeed available on Amazon Bedrock on November 10, 2026, offering a 1-million-token context window through global, US and India inference profiles. Moonshot AI reports that the Highspeed variant generates output two to three times faster than K3.1 Pro.

The underlying model’s launch date was November 4, 2026, ahead of this Bedrock deployment. K3.1 Pro is a post-trained version of Kimi K3, retaining the 3T-class open-weight architecture and context window while using substantially more post-training compute. Moonshot AI says the additional training targets long-horizon agentic work and fewer factual errors, with improvements in financial modeling, office documents, and coding for game engines, 3D scenes and computer-aided design scripts.

In agentic coding, a single task can require many sequential model calls: reading files, planning a change, editing code, running tests and fixing failures. A…
