Kimi ships K3.1 Pro and a Highspeed variant on Kimi Code

Kimi K3.1 Pro and K3.1 Pro Highspeed

Kimi made K3.1 Pro generally available on Kimi Code and released K3.1 Pro Highspeed, which has the same capabilities and outputs about 2–3× faster. K3.1 Pro has 3T parameters and a 1M context window, accepts image and video input, and runs only in thinking mode. Kimi says coding, 3D creation and financial research and modeling are notably improved.

Why it matters: The Highspeed variant trades about 2× the quota for roughly 2–3× faster output, while tool calls and script execution do not speed up.
