Alibaba Qwen-Image-3.0

Unified image generation and editing that balances visual quality, layout fidelity, and response speed

POSTauray-serverless/alibaba/qwen-image-3-0
openapi.jsonllms.txt

One of Auray's catalogue models: the same key, the same credits, the same job lifecycle as every other address.

Its request shape is published below. Whether it runs right now is GET /v1/catalogue's word, with no key needed: its addresses say connected for an address that runs, and a submit to any other is refused before anything is charged — described answers 501 model_not_connected, paused 503 model_disabled.

Category text-to-image · Scope image:write (or external:write on an older key) · Price Credits per megapixel (counted as width*height): 2.3842. From 1.0486 to 2.3593 megapixels a request. Priced up to height 1536, width 1536; past that a request is refused before any charge. Plus 0.25 credits per input image (counted as items:inputs.referenceImages), up to 3 input images. Quoted when you submit, at the most the request can cost; the charge settles to what the job cost and never above the quote. The submit's answer carries the quote as credits_quoted, and credits_charged says what has been taken.

#Input

FieldTypeRequiredDefaultDescription
inputsobjectno—
inputs.referenceImagesstring[]no—List of reference images (an http(s) URL; upload a local file first and send its read URL). Documented range: 1 to 3.
positivePromptstringyes—Text prompt describing elements to include in the generated output. Documented range: 1 to 32,000 characters.
negativePromptstringno—Prompt to guide what to exclude from generation. Ignored when guidance is disabled (CFGScale ≤ 1). Documented range: 2 to 16,000 characters.
widthintegerno1024Width of the generated media in pixels. Documented range: 1 or more.
heightintegerno1024Height of the generated media in pixels. Documented range: 1 or more.
seedintegerno—Random seed for reproducible generation. When not provided, a random seed is generated in the unsigned 32-bit range. Documented range: 0 to 2,147,483,647.
settingsobjectno—
settings.promptExtendbooleannotrueEnable LLM-based prompt rewriting to expand and clarify inputs. Affects reproducibility.
settings.promptExtendModestringno"direct"Rewriting strategy for promptExtend. One of "direct", "agent".
outputTypestringno"URL"Image output type. One of "URL".
outputFormatstringno"JPG"Specifies the file format of the generated output. The available values depend on the task type and the specific model's capabilities. - `JPG`: Best for photorealistic images with smaller file sizes (no transparency). - `PNG`: Lossless compression, supports high quality and transparency (alpha channel). - `WEBP`: Modern format providing superior compression and transparency support. - `MP4`: Widely supported video container (H.264), recommended for general use. - `WEBM`: Optimized for web delivery. - `MOV`: QuickTime format, common in professional workflows (Apple ecosystem). - `GIF`: Animated image format (no audio), suitable for short loops or previews. - `MP3`: Compressed audio, smaller file size. - `WAV`: Uncompressed, high-quality audio. - `FLAC`: Lossless compression. - `OGG`: Open-source compressed audio format (Vorbis codec). - `SVG`: Scalable Vector Graphics. - `TIFF`: High-quality output supporting layers. - `GLB`: Binary glTF format for 3D models, including geometry, textures, and PBR materials. > [!NOTE] > **Transparency**: If you are using features like background removal or LayerDiffuse that require transparency, you must select a format that supports an alpha channel (e.g., `PNG`, `WEBP`, `TIFF`). `JPG` does not support transparency. One of "JPG", "PNG", "WEBP".
outputQualityintegerno95Compression quality of the output. Higher values preserve quality but increase file size. Documented range: 20 to 99.
safetyobjectno—
safety.checkContentbooleanno—Enable or disable content safety checking. Increases total generation time. Always on: a false is sent as true.
advancedFeaturesobjectno—
advancedFeatures.watermarkobjectno—
advancedFeatures.watermark.textstringno—Watermark text. Documented range: 2 to 32 characters.
advancedFeatures.watermark.imagestringno—Watermark image (an http(s) URL; upload a local file first and send its read URL). A URL.
advancedFeatures.watermark.displayPositionstringno—Watermark position. One of "top-left", "top-center", "top-right", "center-left", "center-center", "center-right", "bottom-left", "bottom-center", "bottom-right", "tiled".
advancedFeatures.watermark.opacitynumberno—Watermark opacity. Documented range: 0.1 to 1.
advancedFeatures.watermark.fontColorstringno—Text color in hex format.
advancedFeatures.watermark.bgColorstringno—Background color in hex format.
idempotency_keystringno—Your own name for this request. Send the same one twice and the second call is answered with the first request rather than charged again. Idempotency-Key: as a header is accepted as an alias — that is the spelling a retrying proxy replays, and the one to use when running a model on auray.run, where a request that outlives its connection is answered 504 and recovered by replay. Omit it and the platform mints one. 1 to 64 characters.

#Rules

Across fields, as the model's documentation states them. Each is judged before anything is charged — warned with a Deprecation header until enforcement starts — and listed as JSON Schema under x-auray-rules in the openapi.json.

  • Send height whenever width is sent. Send width whenever height is sent.
  • When settings.promptExtend is false, do not send settings.promptExtendMode.
  • When inputs.referenceImages is sent, settings.promptExtendMode must be "direct".
  • When advancedFeatures.watermark is sent: send exactly one of advancedFeatures.watermark.text or advancedFeatures.watermark.image.

#Example

curl -X POST https://queue.auray.run/auray-serverless/alibaba/qwen-image-3-0 \
  -H "Authorization: Bearer $AURAY_API_KEY" \
  -H "content-type: application/json" \
  -d '{
  "positivePrompt": "a brass orrery on a walnut desk, morning light from a window to the left"
}'

The same body on https://auray.run runs synchronously and answers the result — unless it usually takes longer than a run may hold its connection, which is refused 400 model_not_synchronous before anything is charged. Options — ?webhook=, ?wait=, priority and timeout headers — are on Submit a request.
