Kimi K2.5 by Moonshot AI is a native multimodal agentic model with 1T-param MoE, Agent Swarm execution, vision-grounded coding, and 256K context.
Capabilities, design details, and architectural traits
Kimi K2.5 is an open-source model from Moonshot AI, built via continual pretraining on roughly 15 trillion mixed visual and text tokens atop the Kimi K2-Base checkpoint. Vision-language understanding is trained in from the start, paired with agentic execution and selectable instant/thinking response modes.
Kimi K2.5 extends the Kimi K2 architecture into one model handling vision, language, and long-horizon agentic execution together, rather than layering multimodality onto a text-only base.
