GPT Image-1.5 - Image to Image

This page is generated from the upstream official OpenAPI documentation. Endpoints, parameters and examples match the official docs; brand and API domain are replaced with ModelFold.

Endpoint

POST /jobs/createTask

Full URL: https://ai.modelfold.online/v1/jobs/createTask

Authentication: every request must include the Authorization: Bearer <API_KEY> header.

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:

Step 1 · Upload Image

Use the File Upload API to upload your source image.

File Upload API — Learn how to upload images and get file URLs

Step 2 · Get File URL

After upload, you'll receive a file URL that you can use in the input_urls parameter.

WARNING

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:

Get Task Details — Learn how to query task status and retrieve generation results

TIP

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

Request Parameters

Body (application/json)

Parameter	Type	Required	Description
`model`	`string`	Yes	The model name to use for generation. Required field. - Must be `gpt-image/1.5-image-to-image` for this endpoint Default：`"gpt-image/1.5-image-to-image"`。 Allowed values：`gpt-image/1.5-image-to-image`。示例：`gpt-image/1.5-image-to-image`。
`callBackUrl`	`string`	No	The URL to receive generation task completion updates. Optional but recommended for production use. - System will POST task status and results to this URL when generation completes - Callback includes generated content URLs and task information - Your callback endpoint should accept POST requests with JSON payload containing results - Alternatively, use the Get Task Details endpoint to poll task status - To ensure callback security, see Webhook Verification Guide for signature verification implementation 示例：`https://your-domain.com/api/callback`。
`input`	`object`	Yes	Input parameters for the generation task
`input.input_urls`	`array<string>`	Yes	Upload an image file to use as input for the API (File URL after upload, not file content; Accepted types: image/jpeg, image/png, image/webp; Max size: 10.0MB)
`input.prompt`	`string`	Yes	A text description of the image you want to generate 示例：`Edit the image to dress the woman using the provided clothing images. Preserve her exact likeness, expression, hairstyle, and proportions. Replace only the clothing, fitting the garments naturally to her existing pose and body geometry with realistic fabric behavior. Match lighting, shadows, and color temperature to the original photo so the outfit integrates photorealistically, without looking pasted on.`。
`input.aspect_ratio`	`string`	Yes	Required. Width-height ratio of the image, determining its visual form. Allowed values：`1:1` / `2:3` / `3:2`。示例：`3:2`。
`input.quality`	`string`	Yes	Required. Quality: medium=balanced, high=slow/detailed. Allowed values：`medium` / `high`。示例：`medium`。
