# Image input limits by model

These are the per-side pixel, aspect-ratio and format limits for first and last frames and reference images on each model. Where a model runs on more than one upstream provider, the table uses the strictest value. Last checked: 2026-11-10.

## Rules for every image

-   Each image is a publicly reachable https URL, up to 2,048 characters.
-   The URL must return the image itself: redirects are not followed, so share links and shortened links fail.
-   Still JPEG, PNG or WebP only, at most 10 MB; animated WebP and GIF are not supported.
-   We fetch each image once and keep a copy; content moderation and the model both use that copy.

## What happens if an image is outside the limits?

For some models we check the size when you create the generation and reject it at once with a 400 `invalid_request`, before anything is held. Otherwise the provider rejects the image, the generation fails with `invalid_request` and the hold is released in full. Resize or crop the image, then create a new generation.
