Auto is OpenRouter’s flagship model router, built for general-purpose usage. It adapts to each request, choosing cost-optimal models and adjusting reasoning effort. It balances task difficulty, benchmark results, live prices,...
What the numbers mean
- Context window2,000,000 tokens
- How much the model can read in one request, counting your prompt, any files and the conversation so far. That is about 1,500,000 words, or 3,000 pages.
- Modalitiestext, image, audio, file, video in, text, image out
- The kinds of content it accepts and the kinds it produces. A model that takes images in can read a screenshot; one that only puts text out cannot draw.
Supported parameters
The settings you can pass with a request. A model that lists tools can call functions; one that lists structured_outputs can be held to a JSON schema.
