}GPT Image 2 API
Pricing — per image, in tokens (USD at $0.02/token). Output token usage grows with both quality and resolution:
| quality | 1k | 2k | 4k |
|---|---|---|---|
| low | 0.32 ($0.0064) | 0.64 ($0.0128) | 1.07 ($0.0214) |
| medium | 2.84 ($0.0568) | 5.78 ($0.1156) | 9.61 ($0.1922) |
| high | 11.38 ($0.2276) | 23.12 ($0.4624) | 38.42 ($0.7684) |
Set background to transparent to get a cut-out subject on a transparent background (PNG with alpha channel), at no extra cost. This is a preview capability, so results can be inconsistent - prompts describing a single isolated subject work best.
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated image.

low, medium, high Alpha channel mode. transparent keeps the alpha channel so the subject is returned on a see-through background (PNG); opaque renders a flat background. Preview feature - results may be unstable, and best used with prompts that describe an isolated subject. Does not affect pricing.

Optional. A publicly accessible HTTPS URL. 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.
