Generate and edit images with OpenAI's GPT-Image-2.5 and GPT-Image-2 via inference.sh CLI.
| Model | App ID | Pick it for |
|---|---|---|
| GPT-Image-2.5 Flare | openai/gpt-image-2-5-flare | Default. Higher quality than GPT-Image-2 at 50% lower latency |
| GPT-Image-2.5 Sunburst | openai/gpt-image-2-5-sunburst | Premium edits: keeps subject and composition, tighter control across multi-turn edits |
| GPT-Image-2 | openai/gpt-image-2 | Previous generation |
All three share the same input schema. The 2.5 models add xhigh and max quality tiers.
Requires inference.sh CLI (
belt). Install instructions
Every GPT-Image app supports text-to-image generation, image editing with reference images, and mask-based inpainting through a single app.
| Feature | Description |
|---|---|
| Text-to-Image | Generate images from text prompts |
| Image Editing | Edit images using reference images |
| Inpainting | Mask-based editing of specific regions |
| Batch Generation | Generate up to 10 images at once |
| Multiple Formats | PNG, JPEG, WebP output |
| Transparent Background | Alpha-channel PNG/WebP output for stickers, icons, product cutouts |
| Flexible Resolution | Any size in 16px increments (256–3840), aspect ratio up to 3:1 |
Sunburst is built to change only what you ask for and preserve the rest.
Prompt for an isolated subject — describing a scene or backdrop makes the model draw one. Requires png (default) or webp output.
Approximate price per 1024x1024 image. Flare and Sunburst cost the same.
