Kimi K2.5 is Moonshot AI's flagship agentic model and a new SOTA open model. It unifies vision and text, thinking and non-thinking modes, and single-agent and multi-agent execution into one model. Fireworks enables users to control the reasoning behavior of the Kimi K2.5 model and inspect its reasoning history for greater transparency.
