Input
| Field | Kind | Default | Description |
|---|---|---|---|
prompt required | text | — | Generation prompt. |
resolution required | one of 1K, 2K, 4K | — | Accepted and ignored. gemini-2.5-flash-image takes no `image_size` argument — the aspect ratio alone decides the output geometry — so this value never reaches the provider and never changes the price. It stays on the contract because requests already send it. |
aspect_ratio required | one of 16:9, 9:16, 1:1 | — | Output aspect ratio. |
seed | number (whole) | — | Seed for reproducible output; omit for a random seed. |
images | JSON | — | Images to edit or blend. 1 to 3 images, each at most 30 MB. |
num_outputs | one of 1 | 1 | Number of outputs generated per job. Only 1 is supported. |
enhance_prompt | true or false | false | Rewrite the prompt before generation. An LLM expands it into a fuller description and the model receives that text instead of the submitted one; the result's `prompt` reports what ran. |
