Image editing with Gemini

POST

https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash-exp-image-generation:generateContent

To perform image editing, add an image as input. The following example demonstrats uploading base64 encoded images. For multiple images and larger payloads, check the image input section.

Limitations

For best performance, use the following languages: EN, es-MX, ja-JP, zh-CN, hi-IN.

Image generation does not support audio or video inputs.

Image generation may not always trigger:

The model may output text only. Try asking for image outputs explicitly (e.g. "generate an image", "provide images as you go along", "update the image").

The model may stop generating partway through. Try again or try a different prompt.

When generating text for an image, Gemini works best if you first generate the text and then ask for an image with the text.
