GPT-Image

Generate and edit images with OpenAI's GPT-Image-2.5 and GPT-Image-2 via inference.sh CLI.

Models

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.

Quick Start

Requires inference.sh CLI (belt). Install instructions

belt login

belt app run openai/gpt-image-2-5-flare --input '{"prompt": "a cat astronaut floating in space"}'

Capabilities

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

Examples

Text-to-Image

belt app run openai/gpt-image-2-5-flare --input '{
  "prompt": "professional product photo of sneakers on a white background, studio lighting",
  "quality": "high"
}'

Multiple Images

belt app run openai/gpt-image-2-5-flare --input '{
  "prompt": "minimalist logo design for a coffee shop",
  "n": 4,
  "quality": "medium"
}'

Image Editing with Reference

belt app run openai/gpt-image-2-5-flare --input '{
  "prompt": "change the background to a beach at sunset",
  "images": ["https://your-image.jpg"]
}'

Precise Edit with Sunburst

Sunburst is built to change only what you ask for and preserve the rest.

belt app run openai/gpt-image-2-5-sunburst --input '{
  "prompt": "change the jacket to red leather, keep the person, pose and background unchanged",
  "images": ["https://your-photo.jpg"],
  "quality": "high"
}'

Maximum Detail

belt app run openai/gpt-image-2-5-flare --input '{
  "prompt": "macro photo of a dragonfly wing, intricate veins, morning dew",
  "quality": "max"
}'

Multi-Image Reference

belt app run openai/gpt-image-2-5-flare --input '{
  "prompt": "combine these two characters into one scene",
  "images": ["https://character1.jpg", "https://character2.jpg"]
}'

Inpainting with Mask

belt app run openai/gpt-image-2-5-flare --input '{
  "prompt": "replace with a red sports car",
  "images": ["https://street-scene.jpg"],
  "mask": "https://car-mask.png"
}'

Transparent Background

Prompt for an isolated subject — describing a scene or backdrop makes the model draw one. Requires png (default) or webp output.

belt app run openai/gpt-image-2-5-flare --input '{
  "prompt": "a single red apple with a green leaf, isolated subject",
  "background": "transparent"
