Kimi Released Kimi K2.5, Open-Source Visual SOTA-Agentic Model

Summary

Kimi K2.5: Visual Agentic Intelligence Today, we are introducing Kimi K2.5, the most powerful open-source model to date.Kimi K2.5 builds on Kimi K2 with continued pretraining over approximately 15T mixed visual and text tokens. Built as a native multimodal model, K2.5 delivers state-of-the-art coding and vision capabilities and a self-directed agent swarm paradigm.For complex tasks, Kimi K2.5 can self-direct an agent swarm with up to 100 sub-agents, executing parallel workflows across up to 1,500 tool calls. Compared with a single-agent setup, this reduces execution time by up to 4.5x. The agent swarm is automatically created and orchestrated by Kimi K2.5 without any predefined subagents or workflow.Kimi K2.5 is available via Kimi.com, the Kimi App, the API, and Kimi Code. Kimi.com & Kimi App now supports 4 modes: K2.5 Instant, K2.5 Thinking, K2.5 Agent, and K2.5 Agent Swarm (Beta). Agent Swarm is currently in beta on Kimi.com, with free credits available for high-tier paid users.Across three agentic benchmarks—HLE, BrowseComp, and SWE-Verified—Kimi K2.5 delivers strong performance at a fraction of the cost.1. Coding with Vision Kimi K2.5 is the strongest open-source model to date for coding, with particularly strong capabilities in front-end development.K2.5 can turn simple conversations into complete front-end interfaces, implementing interactive layouts and rich animations such as scroll-triggered effects. Below are examples generated by K2.5 from a single prompt with image-gen tool:Beyond text prompts, K2.5 excels at coding with vision. By reasoning over images and video, K2.5 improves image/video-to-code generation and visual debugging, lowering the barrier for users to express intent visually.Here is an example of K2.5 reconstructing a website from video:This capability stems from massive-scale vision-text joint pre-training. At scale, the trade-off between vision and text capabilities disappears — they improve in unison.Below is an example of K2.5 reasoning o...
