Text-to-image, or pass `image_list` to edit reference images. **Pricing** — per image, in tokens (USD at $0.02/token). `low` / `medium` / `high` match `gpt-image-2`; `xhigh` and `max` extend it: | quality | 1k | 2k | 4k | |---|---|---|---| | low | 0.39 ($0.008) | 0.78 ($0.016) | 1.17 ($0.023) | | medium | 3.45 ($0.069) | 6.9 ($0.138) | 10.35 ($0.207) | | high | 13.72 ($0.274) | 27.44 ($0.549) | 41.16 ($0.823) | | xhigh | 27.44 ($0.549) | 54.88 ($1.098) | 82.32 ($1.646) | | max | 68.6 ($1.372) | 137.2 ($2.744) | 205.8 ($4.116) | Set `background` to `transparent` to keep the alpha channel (PNG cut-out), at no extra cost. Returns an `img_uuid`; poll GET /api/v1/jobs/detail (or use `custom_callback_url`) to get the generated image. ## OpenAPI ````yaml api-reference/image-api/openapi-gpt-image-2-5-flare.json POST /api/v1/images/generations openapi: 3.1.0 info: title: GoEnhance API - GPT Image 2.5 Flare description: GPT Image 2.5 Flare version: 1.0.0 servers: - url: https://api.goenhance.ai security: [] paths: /api/v1/images/generations: post: tags: - ImageAPI summary: GPT Image 2.5 Flare description: >- GPT Image 2.5 tuned for speed — for high-quality everyday batch generation.

When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail. If your server does not respond with HTTP 200, the notification is retried up to 3 times, with a 3-second timeout per attempt. example: https://your-server.com/goenhance/callback required: - model - prompt example: model: gpt-image-2 prompt: a glossy red sneaker, product shot, isolated subject image_size: 1k quality: low background: transparent responses: '200': description: '' content: application/json: schema: type: object properties: code: type: integer msg: type: string data: type: object properties: img_uuid: type: string cost: type: number description: >- Tokens deducted for this request. This is the amount actually charged, so it already reflects any discount active on your account and can be lower than the listed price.
