Overview

Generate images from input images using the GPT Image 1.5 Image To Image model. This model allows you to edit or modify existing images with text prompts. The process consists of two steps: create a generation task and query task status and results.

File Upload Requirements

Before using this API, you need to upload your image files:
1

Upload Image

Use the File Upload API to upload your source image.

2

Get File URL

After upload, you’ll receive a file URL that you can use in the input_urls parameter.
  • Supported formats: JPEG, PNG, WebP
  • Maximum file size: 10MB
  • Maximum 16 input URLs per request
  • Images should be appropriate and follow usage guidelines

Query Task Status

After submitting a task, use the unified query endpoint to check progress and retrieve results:

For production use, we recommend using the callBackUrl parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.

Authorizations
