GPT Image Series

All four models in the GPT Image series are served on POST /v1/tasks — the request URL does not change between them. They share the same actions and request shape; the differences are the aspect-ratio and resolution values, the line-specific parameters, and billing. Picking a model only changes the model field.

Available models

GPT Image 1

gpt-image-1 · text-to-image, edits with up to 15 references, mask inpainting and transparency; billed on actual token usage

GPT Image 1.5

gpt-image-1.5 · the same actions and parameters as gpt-image-1, with text output as an extra billing dimension; billed on actual token usage

GPT Image 2 Official

gpt-image-2 · 15 aspect ratios, 1k / 2k / 4k resolutions, up to 16 references, mask inpainting and WebP output; billed on actual token usage

GPT Image 2 Reverse

gpt-image-2-rev · text-to-image and edits with up to 15 references; fixed per-image pricing at 1k, 2k, or 4k

Choose a model

Need	Recommended model	Why
`2k` / `4k` output, or an aspect ratio beyond `1:1` `2:3` `3:2`	`gpt-image-2`	It is the only model that accepts `resolution`, and it supports 15 aspect ratios
A fixed per-image price before submission	`gpt-image-2-rev`	Billing is fixed by output resolution, independent of aspect ratio and prompt length
Mask inpainting, transparent backgrounds, or output-format control	`gpt-image-1` `gpt-image-1.5` `gpt-image-2`	All three official lines expose these line-specific parameters
WebP output	`gpt-image-2`	The other three models output `png` and `jpeg` only
Multi-image reference editing	All four	`gpt-image-2` accepts up to 16 images; the other three accept up to 15

The models never switch automatically: the model field selects the model, and its own page is authoritative for the parameters it accepts.

These are identical on all four models:

Item	Value
Endpoint	`POST /v1/tasks` (async task, see Task system)
Actions	`generate` text-to-image · `edit` reference-image editing (requires `image_urls`)
Default aspect ratio	`1:1`; the available set differs per model, see each model page
Output count	One image per request
Not supported	`seed`

Unified request

curl -X POST https://www.qingbo.dev/v1/tasks \
  -H "Authorization: Bearer $WAVE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-image-2",
    "action": "generate",
    "prompt": "A blue ceramic cup on a white table in soft natural light",
    "aspect_ratio": "1:1",
    "n": 1
  }'

Swap model for any model ID on this page and the request still runs. 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.
