Particle-1

New

by Particle AiReleased 28 October 2026

Particle-1 reads text and pictures and writes text back, taking in about 1000 pages at once and writing up to 130 pages in one go. It is built for software work: sitting down with a codebase, making changes across many files, and running tasks in the terminal. It can think through a problem before answering and work with your own tools, and it keeps its answers short on the meter, so long coding sessions cost less than with wordier models. It cannot search the web, so jobs that need fresh pages pulled from the internet need a different kind of model.
