6 models
Kimi K2.7 Code
AvailableMoonshot's open coding-focused agentic model built on K2.6, with native vision/video input, forced thinking mode, and stronger long-horizon software-engineering performance.
Kimi K2.6
AvailableMoonshot's open native multimodal agentic model for long-horizon coding, visual interface generation, and autonomous tool orchestration.
Kimi K2.5
AvailableOpen multimodal Kimi model that adds native visual agentic intelligence, instant and thinking modes, and agent-swarm workflows on top of the K2 base.
