Add "aspect_ratio": " to the JSON body. Supported values:
| Ratio | Use case |
|---|---|
| ------- | ---------- |
1:1 | Social media, thumbnails |
16:9 / 9:16 | Widescreen, mobile stories |
4:3 / 3:4 | Presentations, portraits |
3:2 / 2:3 | Photography |
2:1 / 1:2 | Banners, headers |
auto | Model picks best ratio (default) |
Set "n": (1-10) to generate multiple images in one request.
Edit an existing image by providing a source image plus an edit prompt.
Uses the same /v1/images/generations endpoint with an added image_url field.
Do NOT use /v1/images/edits with multipart — xAI requires JSON.
IMPORTANT: For local files, use Python to build the payload JSON file, then curl with @file.
Inline base64 in curl args causes "Argument list too long" for images >~100KB.
NOTE: This is NOT true image editing — the API generates a new image inspired by the source.
It cannot make pixel-precise edits (e.g. changing only a car's color while keeping everything else identical).
