|---|---|---|
| seed | — | The seed for the random number generator. |
| promptrequired | string | The text prompt to generate an image from. |
| sync_mode | boolean | If `True`, the media will be returned as a data URI and the output data won't be available in the request history. |
| num_images | integer | The number of images to generate. |
| resolution | stringenum: 1K, 2K, 4K | The resolution of the image to generate. |
| aspect_ratio | — | The aspect ratio of the generated image. Supports extreme ratios: 4:1, 1:4, 8:1, 1:8. Use "auto" to let the model decide based on the prompt. |
| output_format | stringenum: jpeg, png, webp | The format of the generated image. |
| system_prompt | string | Optional system instruction that steers the model's persona and output style across the request. Leave blank to omit; when provided, it is sent as the system instruction to Gemini (or as a system message on OpenAI-compatible providers). |

| enable_web_search | boolean | Enable web search for the image generation task. This will allow the model to use the latest information from the web to generate the image. |
| limit_generations | boolean | Experimental parameter to limit the number of generations from each round of prompting to 1. Set to `True` to to disregard any instructions in the prompt regarding the number of images to generate and ignore any intermediate images generated by the model. This may affect generation quality. |
| pdf_url | — | Optional PDF document to use as input context. Accepts an http(s)/data URL (downloaded and sent inline, max 15MB). |
| audio_url | — | Optional audio file to use as input context. Accepts an http(s)/data URL (downloaded and sent inline, max 15MB). |
