Edit images with GPT Image 2.5. Precision single-element edits that keep the rest of the scene untouched. Coming soon on Muapi — no subscription.
About this model
GPT Image 2.5 Image to Image is OpenAI's newest instruction-based image editing model, announced September 8, 2026. It changes only what you ask for while keeping the rest of a scene untouched, and keeps earlier edits intact across a multi-turn chain instead of drifting or degrading like GPT Image 2. Choose the Flare tier for fast iteration or the Sunburst tier for maximum precision on a single critical edit. Muapi is bringing this endpoint online as soon as OpenAI opens general API access.

|---|---|---|---|
| Prompt | string | Text instructions describing the desired transformation. Maximum 20,000 characters. | Change only the beverage bottle in the center to a matte black can labeled "PEAK", keeping the exact same lighting, shadows, reflective surface, background props, and camera angle. Do not change anything else in the scene. |
| Image URLs | array | Upload or provide input images to transform. Up to 16 images supported. | https://d3adwkbyhxyrtq.cloudfront.net/webassets/videomodels/gpt-image-2-image-to-image-in.jpg |
| Model | Enum (2 options) | GPT-Image-2.5 Flare is the default, fastest tier. GPT-Image-2.5 Sunburst is a slower tier tuned for maximum edit precision on premium creative work. | flare |
| Aspect Ratio | Enum (6 options) | Output image aspect ratio. Note: images with aspect ratio 'auto' (or unspecified) will only be converted to 1K; 1:1 cannot be converted to 4K — otherwise the task will fail to create. | auto |
| Resolution | Enum (3 options) | Image resolution. Note: images with a 1:1 aspect ratio cannot be converted to 4K. Images with aspect ratio 'auto' (or unspecified) will only be converted to 1K; otherwise the task will fail to create. | 2K |
| Quality | Enum (3 options) | Generation quality. 'low' and 'medium' use a faster, cheaper backend; 'high' uses the higher-fidelity backend. | high |

Provide a source image — upload or link up to 16 reference images.
Write a precise instruction — state what should change and what must stay identical (e.g. "replace only the bottle, keep the lighting and background exactly as shown").
Pick a model tier — flare (default) for speed, or sunburst for maximum edit precision.

It is OpenAI's newest instruction-based image editing model, announced September 8, 2026 alongside ChatGPT Images 2.5, available via the GPT-Image-2.5 Flare and Sunburst API models.
Not yet. This endpoint is in early access with OpenAI. Muapi will enable it as soon as general API access opens — no action needed on your part.
GPT Image 2.5 is more reliable at changing only the requested element while preserving the rest of a complex scene, and keeps earlier edits intact across multiple turns instead of drifting.
Flare is the default, fastest tier. Sunburst is a slower tier tuned for maximum precision when a single edit needs to be exactly right, such as final campaign creative.
Yes. [GPT Image 2 Image to Image](/playground/gpt-image-2-image-to-image) is live now while GPT Image 2.5 is in development.
