Overview
Kimi K2.5 is a native multimodal model from Moonshot AI. It accepts text, image and video input and supports thinking and non-thinking modes, so it can be used for both dialogue and agent tasks. Moonshot AI points to its strengths in visual coding, agent work and visual understanding. It returns text.
Kimi K2.5 has a 256K-token context window and can generate up to 16K output tokens. It accepts text, image and video input and returns text output. It was released on January 27, 2026.
Capabilities
Kimi K2.5 supports reasoning, tool calling, MCP, prompt caching and web search. It accepts text, image and video as input and produces text as output.
Thinking mode handles multi-step reasoning, non-thinking mode answers quickly, and tool calling, MCP and web search let Kimi K2.5 act as an agent. Prompt caching lowers the price of repeated context.
Pricing
Kimi K2.5 costs $0.57 per 1M input tokens and $3.00 per 1M output tokens. Cache reads are $0.10 per 1M tokens.
Kimi K2.5 is available through RealRelay's OpenAI-compatible API.
Use cases
Use Kimi K2.5 for visual coding: give it a screenshot or short video of an interface and ask for code that reproduces it, with tool calling to run and check the result.
It also suits agent tasks that search and call tools, and question answering over long documents or images within its 256K-token context window.
