Kimi K3.1 Pro is Moonshot AI's flagship open-weight multimodal reasoning model, released in October 2026 as a post-trained successor to Kimi K3. It is built for long-horizon coding and agent work, and scores 46.5 on the Artificial Analysis Intelligence Index.

It accepts text, image and video input with a 1,048,576-token context window. You set how much it reasons with the reasoning effort setting: none, low, high or max. Hormouz serves it behind an OpenAI-compatible API, so existing OpenAI SDK code works with only the base URL and key changed.

It costs $2 per million input tokens and $10 per million output tokens on Hormouz, paid in rial from your Hormouz balance, with no monthly fee.
