Kimi Code has released the K3.1 Pro model series, featuring a 1M context window and improved capabilities in coding and financial modeling. The update includes a high-speed variant and integration support for various developer tools and APIs.
Why it matters
The release represents the ongoing rapid advancement of large language models and their increasing integration into professional software development workflows.
This page covers the models Kimi Code provides, how to switch models in each client, third-party tool setup, and common API issues.
Kimi Code currently offers six model IDs across K3.1 Pro (including K3.1 Pro Highspeed), K3 (including its 256K context variant), K2.8 Preview, and K2.7 Code Highspeed.

K3.1 Pro is now fully rolled out in Kimi Code—the first model of the new K3.1 series and our most capable 3T-class model to date, with a 1M context window and substantial improvements across coding, 3D creation, and financial research and modeling.
We're also releasing Kimi K3.1 Pro Highspeed , which—with identical model capabilities—delivers approximately 2–3× the speed of K3.1 Pro for more responsive interactions.
