gpt-image-2-rev provides GPT Image 2 text-to-image generation and reference-image editing through an aggregator. Pricing is fixed by output resolution, making the per-image cost known before submission.

This is a reverse line, not the official OpenAI API. Use gpt-image-2 for quality tiers, masks, transparent backgrounds, and output-format controls. QWave never switches between the two lines automatically.

Quick start

curl -X POST https://www.qingbo.dev/v1/tasks \
  -H "Authorization: Bearer $WAVE_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: image-rev-001" \
  -d '{
    "model": "gpt-image-2-rev",
    "action": "generate",
    "prompt": "Minimal perfume product photography, warm white background, soft studio light",
    "aspect_ratio": "4:5",
    "resolution": "1k",
    "n": 1
  }'

curl -X POST https://www.qingbo.dev/v1/tasks \
  -H "Authorization: Bearer $WAVE_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: image-rev-edit-001" \
  -d '{
    "model": "gpt-image-2-rev",
    "action": "edit",
    "prompt": "Keep the subject and replace the background with a pale green studio",
    "image_urls": ["https://cdn.example.com/source.png"],
    "aspect_ratio": "1:1",
    "resolution": "1k",
    "n": 1
  }'

A successful submission returns a task_id. Retrieve the result with GET /v1/tasks/{task_id}, wait inline with Prefer: wait, or configure a webhook.

Request parameters

string

required

Must be gpt-image-2-rev.

string

default:"generate"

generate: create an image from text
edit: edit reference images; requires image_urls

string

required

The image description or editing instruction.

string[]

Reference image URLs. Required for edit; up to 15 images. References do not add a fee.

string

default:"1:1"

One of 1:1, 3:2, 2:3, 4:3, 3:4, 5:4, 4:5, 16:9, 9:16, 2:1, 1:2, 3:1, 1:3, 21:9, or 9:21.

string

default:"1k"

Output resolution: 1k, 2k, or 4k.

integer

default:"1"

Number of images to generate. Value: 1. Each request returns one image.

See Submit a task for callback_url, callback_events, Prefer: wait, Idempotency-Key, and the maximum-cost header. The reverse line does not support quality, mask_url, background, output_format, output_compression, moderation or seed — those belong to the official line. Any other parameter returns 400 and is not billed.

Limits

Condition	Limit
Per request	One image
`action: "edit"`	At least one reference image is required
Reference images	Up to 15

Pricing

Successful images are billed at a fixed price per image, with a different rate at 1k, 2k and 4k. Rates are in price_config on GET /v1/models and in the console’s Model Market. What a single call actually cost is the cost field on the task response — an integer quota at 500,000 quota = 1 USD, not dollars. generate and edit cost the same, reference images add no fee, and neither aspect ratio nor prompt length changes the price — resolution is the only billing dimension, so the cost of a call is known before it is sent. A resolution other than 1k, 2k or 4k settles at the 1k price. Only a successfully generated image is billed. Failed and cancelled tasks, and tasks that return no usable image, are refunded in full.

Response

Completed task

{
  "task_id": "taski_example",
  "model": "gpt-image-2-rev",
  "action": "edit",
  "status": "completed",
  "progress": "100%",
  "result": {
    "images": [
      {
        "url": ["https://cdn.example.com/result.png"]
      }
    ]
  },
  "billing_status": "settled",
  "cost": 4781
}

result.images carries the generated image. The full field reference is in Task status.
