Kimi K2.5 is Kimi's most intelligent and versatile model to date, featuring a native multimodal architecture that supports both visual and text input, thinking and non-thinking modes, and dialogue and agent tasks. Built as a native multimodal model, K2.5 delivers state-of-the-art coding and vision capabilities and a self-directed agent swarm paradigm.

Key features include coding with vision capabilities where K2.5 can turn simple conversations into complete front-end interfaces with interactive layouts and rich animations such as scroll-triggered effects. The model excels at coding with vision by reasoning over images and video, improving image/video-to-code generation and visual debugging. K2.5 supports autonomous visual debugging where it visually inspects its own output and iterates on it autonomously. The agent swarm capability allows self-direction of up to 100 sub-agents executing parallel workflows across up to 1,500 tool calls.

The model works through a native multimodal architecture trained on approximately 15T mixed visual and text tokens. For complex tasks, Kimi K2.5 automatically creates and orchestrates an agent swarm without any predefined subagents or workflow. The agent swarm uses Parallel-Agent Reinforcement Learning (PARL) with a trainable orchestrator agent that decomposes tasks into parallelizable subtasks executed by dynamically instantiated, frozen subagents.

Benefits include reducing execution time by up to 4.5x compared to single-agent setups and enabling more complex, long-horizon workloads. Use cases include handling high-density, large-scale office work end to end, creating documents, spreadsheets, PDFs, and slide decks directly through conversation, and performing tasks like adding annotations in Word, constructing financial models with Pivot Tables, and writing LaTeX equations in PDFs.

Kimi K2.5 is available via Kimi.com, the Kimi App, the API, and Kimi Code. The target users include software engineers, office productivity users, and developers working with multimodal AI applications. Kimi Code works in terminals and integrates with various IDEs including VSCode, Cursor, and Zed.
