Moonshot AI's new Kimi model can read images and write code, and it is built to coordinate teams of AI helpers working together.

Download
Not downloadable: it runs on the maker's own servers.

The details
Moonshot AI's Kimi K2.5 is a point update to Kimi K2 that reads images and focuses on visual coding and a self-directed Agent: An AI that doesn't just answer but takes steps on its own to finish a task: searching the web, running code or using apps. swarm approach, listed on OpenRouter: A service that gives developers one place to use hundreds of models from many labs. New models often appear there early, sometimes anonymously.. It was further pretrained on roughly 15T mixed training Tokens: The small chunks of text a model reads and writes, about three-quarters of a word each. Prices and limits are counted in tokens..
Model ID: The exact name developers type to use a model, like gpt-5-mini. New IDs often show up in a lab's systems before the official announcement, which is how trckr spots many releases early.
