Independent Image to Layers workspace: generate a PNG here, then keep editing or separate its visual parts into layers.
A useful prompt names the subject, scene, composition, style and light. For edits, separate what should change from what should stay.
These are Image Gen concept illustrations for the prompt ideas below, not verified Flare or Sunburst API samples.
Product scene direction
Use the product in the reference photo. Place it on a pale stone shelf with soft light from the left. Keep its shape, packaging colors and printed wording. Change the background to a quiet studio setting.
Suggested setup · 1:1 · Reference image edit
Campaign and poster direction
Create a portrait event poster with the headline “WEEKEND MARKET”. Put the headline at the top, a simple illustration of a market stall in the center, and open space at the bottom for event details. Use navy and warm cream.
Suggested setup · 4:5 · Text prompt
Reference composition direction
Use the product from image 1, the setting from image 2, and the lighting from image 3. Create a landscape composition with the product on the right and open space on the left. Preserve the product’s shape and colors.
Suggested setup · 16:9 · Multiple reference images
Prompt starters for you to adapt; results depend on the prompt and references.
With several references, describe which image supplies the subject, which supplies the setting, and which supplies the lighting or style. Provide the exact words you need in the image. Check the result for spelling, clarity and placement.
Both GPT Image 2.5 models support generation from text and editing with reference images. Choose according to the kind of work you are making.
OpenAI positions Flare as the default for most applications, including social content, product experiences and visual prototyping.
Start here for everyday images and exploring a visual direction.
Sunburst focuses on tighter control for detailed creative work and image edits, including campaign concepts and product imagery. OpenAI notes that it can take longer to generate.
Choose it when preserving details through an edit matters most.
OpenAI released ChatGPT Images 2.5 on September 8, 2026. Its announcement highlights improvements in reference fidelity, focused editing and interpreting complex visual instructions.
OpenAI reports better preservation of subjects from reference photos, with more natural lighting and texture. Describe the features that matter when you place a subject in a new setting.
The update is designed to follow targeted edits more closely. Specify the element to change, then name the surrounding details you want to retain.
Use a defined composition and visual style for a poster, presentation image or campaign concept. Review text and placement in the result, especially when the layout is precise.
Write what you want to create. For an edit or reference-based image, add your source images and explain the role of each one.
Select Flare or Sunburst, choose an aspect ratio, and set 1K, 2K or 4K resolution. This workspace generates one image at Medium quality.
Inspect the image and download the PNG. To work on its parts, send it to the image-to-layers tool for a separate layer-splitting step.
The resolution tier and aspect ratio work together. A 4K setting does not mean that every image is 4096 × 4096 pixels.
Aspect ratio examples for square 1:1, landscape 16:9, and portrait 9:16 images.
Useful for product tiles, avatars, and square social posts.
Useful for banners, video thumbnails, and presentation slides.
Useful for mobile covers, stories, and poster layouts.
| Aspect ratio | 1K | 2K | 4K |

| Square · 1:1 | 1024 × 1024 | 2048 × 2048 | 2880 × 2880 |
| Landscape · 16:9 | 1536 × 864 | 2048 × 1152 | 3840 × 2160 |

OpenAI: Introducing ChatGPT Images 2.5OpenAI recommends Flare for most everyday image-generation applications. Sunburst is intended for detailed creative work and tighter editing control, with longer generation times. Both are available in this workspace.
Yes. Add up to 16 PNG, JPEG or WebP images, with a maximum of 10 MB per file. Describe how each reference should guide the result and which details should remain.
This page offers 1K, 2K and 4K tiers. At 4K, a 16:9 image is 3840 × 2160, while a square image is 2880 × 2880. Dimensions vary by ratio, and resolutions above 2560 × 1440 are experimental.
Upload the product image and specify the background change, then list the product details to preserve. GPT Image 2.5 is designed for more focused edits, but you should still inspect the result for unintended changes.
Sketch, on-image comments and shared prompts are features of the ChatGPT interface described in OpenAI’s release. This page provides prompt-based generation and reference-image editing, followed by PNG download or a separate image-to-layers step.
