Summary

Generates images from text prompts using Google's Gemini 3.x or 2.5 Flash models, with options for aspect ratio, resolution, and output format.

Inputs

  • model (required) — The Gemini model to use for generation (e.g., gemini-3.1-flash-image-preview, gemini-2.5-flash-image).
  • prompt (required) — The text prompt describing the desired image.
  • aspectRatio — The aspect ratio of the output image (e.g., 1:1, 16:9, 9:16).
  • resolution — The image resolution (e.g., 512px, 1K, 2K, 4K). Only available for certain high-res models.
  • outputFormat — Format of the output data (binary, url, dataUrl, or base64).
  • throwOnFailure — If true, throws an error on generation failure; if false, returns success:false with details.

Output shape

A JSON object with a success flag and a count of generated images. Includes a binary property (if format is binary) or a text string/array property (for other formats).

For binary output, image count determines property names (e.g., data, data_1). If showRawResponse is true, the original API response is included.

Examples

Example 1: Generate a square image from a text prompt in binary format.

Set model to 'gemini-3.1-flash-image-preview', aspect ratio to '1:1', output format to 'binary'.

Example 2: Generate a landscape image and get the URL.

Set model to 'gemini-2.5-flash-image', aspect ratio to '16:9', output format to 'url'.
