What is the GPT Image 2 API?
GPT Image 2 is OpenAI's image generation and editing model, exposed on reAPI as one async endpoint that covers text-to-image, image-to-image with up to 16 reference URLs, and mask-based inpainting. Prompts run up to 32,000 characters and output picks from 14 aspect ratios at 1K, 2K or 4K — 4K is reserved for the six widescreen ratios (16:9, 9:16, 2:1, 1:2, 21:9, 9:21). Billing is per image.
What you can build with this model
Real-world workflows and production use cases you can build and ship with this model.
Refresh product photos in batches
Edit existing e-commerce shots without a reshoot. Swap colorways, change backgrounds, or restyle for a new season — GPT Image 2 keeps the original product untouched while the surrounding scene gets reworked. One image URL goes in, an updated render comes out. Run a hundred SKUs through the same prompt template and the catalog stays visually consistent.
Edit a photo
Generate ad creatives at draft speed
Spin four hero variants from a single prompt with the stable channel of GPT Image 2 (n=4). Pick the winner, ship to social, iterate on the rest. The basic channel handles single-image drafts when budget matters more than choice. Same endpoint either way — switch with one string in the request body.
Compose scenes from reference images
Pass up to 16 reference images and the model fuses them into a new composition that respects your brand. Add a mask URL for inpainting — replace a sky, repaint a wall, or swap a logo without redrawing the surrounding pixels. GPT Image 2 handles the fine edges and texture transitions automatically.
Pricing

Why reAPI
Two variants, one endpoint
Send model `gpt-image-2` for the cheap basic channel — single image, flat per-resolution price. Send `gpt-image-2-official` for the stable channel: batches up to four, quality tiers, inpainting masks, transparent backgrounds, output format and compression control. Switch channels by changing one string. No client refactor, no second SDK to learn.
Credits, not surprises
1 credit equals $0.001 USD. The live estimator on this page costs your exact configuration before you submit, so the GPT Image 2 charge in your dashboard matches what you saw at request time. No metering surprises, no minimum commitment, no monthly platform fee — only what your app actually generates.
Async by default
Submit a task, get an ID instantly, poll until done. Nothing to time out, nothing to retry. The same async pattern slots into serverless functions, queue workers, and edge runtimes — wherever you run, the GPT Image 2 endpoint fits the shape your stack already uses.
Integrate GPT Image 2 in three steps
- step 01
Create an API key
Sign up and grab a key from the dashboard. Free signup credits cover a few hundred basic-channel generations before you ever top up — enough to ship the first feature and watch the bill stay at zero.
Open - step 02
Submit a generation
POST a JSON body with `model`, `prompt`, and any optional fields to `/api/v1/images/generations`. Pick `gpt-image-2` for cheap drafts or the stable variant for the full feature set. The endpoint returns a task ID immediately so the request never blocks your handler.
Open - step 03
Poll the result
GET `/api/v1/tasks/:id` until status flips to `completed`. The GPT Image 2 response holds image URLs on our CDN — stable for seven days. Mirror them to your own storage if you need them longer than that.

}'Parameter validation failed
Rejected synchronously with the failing field named. Check enum values, ranges, and URL fields — nothing is charged.
Authentication or balance issue
401 means a missing or invalid Bearer key; 402 means the reserve exceeds your balance. Manage keys and credits in the console.
Content or material rejected
Reference material and outputs pass automated moderation. Rejected tasks fail with a clear error and a full refund.
Task failed or timed out
A task that reaches a failed state is never charged — the reserve refunds automatically. Keep the task id and retry when ready.
Frequently asked questions
Common questions about this model.
GPT Image 2 is OpenAI's text-to-image and image-editing model. reAPI exposes it through one async endpoint with credit-based pricing, so you skip the upstream billing surface entirely while still calling the same underlying model. Two channels are available, priced and feature-scoped independently — pick the one that fits each request.
