Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read
outputsfrom the completed response

OpenAI GPT Image 2 Edit
Precision image editing powered by OpenAI's GPT Image 2. Modify existing images with natural language — swap backgrounds, combine multiple sources, add or remove elements — while preserving the original style and quality.
- Need to generate from scratch? Try OpenAI GPT Image 2.
Highlights
Multi-image synthesis — Accepts up to 16 input images in a single request. Combine product photos into a gift basket, merge reference images into a cohesive scene, or apply style from one image to another.
Context-aware editing — Understands what to change and what to preserve. Edits blend naturally with surrounding pixels, maintaining lighting consistency, material textures, and perspective.
High-fidelity input — Processes source images at full resolution without downsampling. Fine details like fabric weave, text on labels, and subtle gradients survive the editing process.
Pricing
| Quality | Standard Size | Large (21:9 / 9:21) |
|---|---|---|
| Low | $0.015 | $0.03 |
| Medium | $0.05 | $0.08 |
| High | $0.20 | $0.30 |
Standard covers most aspect ratios (1:1, 2:3, 3:2, 4:3, 16:9, etc). Large applies to ultra-wide/tall formats only.
When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| Product photo background swaps | Generating images from zero (use Generation model) |
| Combining multiple items into one scene | Pixel-perfect mask control (limited stability) |
| Packaging and label visualization | Real-time interactive editing |
| Style transfer across images | Video frame manipulation |
| Adding text overlays to existing photos | Simple crops or color adjustments |
Input Requirements
- Images provided as publicly accessible URLs
- Supported formats: PNG, JPEG, WebP
- Up to 16 images per request
- Max file size: 50MB per image
- For best results: use consistent lighting and resolution across input images
