Kimi K3.1 Pro is the first model in Moonshot AI's K3.1 series, a post-trained version of Kimi K3 with a 1M-token context window and native visual understanding. It improves on K3 in coding (Unreal, Unity and Godot projects), 3D and CAD modeling, and financial research, with a lower hallucination rate. Thinking is always on, with low, high and max reasoning effort.
