Input

Describe the image you want to generate. Any language is supported, up to 5000 characters.

0/5000

Output aspect ratio. The actual pixel size also depends on the resolution tier.

Output resolution tier. Only 1K and 2K are supported. 2K takes noticeably longer to generate.

Background type. transparent outputs a PNG or WebP with a real alpha channel and cannot be used with JPEG. When using transparent, describe only the subject — prompts that mention a background, scene, surface, etc. may produce a non-transparent result.

Output image format. JPEG has no alpha channel, so it cannot be combined with a transparent background.

Rewrites the prompt into a fuller scene description before generating, which noticeably improves quality. Enabled by default (also when the parameter is omitted); pass false to turn it off.

The same seed with the same prompt and parameters reproduces the same image on the same model version. The seed actually used is returned with the result.

A configurable parameter. Defaults to true in the Playground.

There is no guarantee that everything can be filtered out; if you are not satisfied with the results, you will need to make your own arrangements.
