Running a model
BriaImage to imageBria Fibo Edit Tools
Unified image editing foundation for recolor, relight, restore, blend, reseason, and sketch
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 image-to-image · Scope image:write (or external:write on an older key) · Price Credits per call: 4. 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
| Field | Type | Required | Default | Description |
|---|---|---|---|---|
inputs | object | yes | — | |
inputs.image | string | yes | — | Image input (an http(s) URL; upload a local file first and send its read URL). A URL. |
positivePrompt | string | no | — | Text prompt describing elements to include in the generated output. Documented range: 1 to 10,000 characters. |
negativePrompt | string | no | — | Prompt to guide what to exclude from generation. Ignored when guidance is disabled (CFGScale ≤ 1). Documented range: 1 to 10,000 characters. |
outpaint | object | no | — | |
outpaint.top | integer | no | — | Number of pixels to extend to the top. Documented range: 0 or more. |
outpaint.bottom | integer | no | — | Number of pixels to extend to the bottom. Documented range: 0 or more. |
outpaint.left | integer | no | — | Number of pixels to extend to the left. Documented range: 0 or more. |
outpaint.right | integer | no | — | Number of pixels to extend to the right. Documented range: 0 or more. |
providerSettings | object | no | — | |
providerSettings.bria | object | no | — | |
providerSettings.bria.color | string | no | — | Color style for the colorize operation. One of "contemporary color", "vivid color", "black and white colors", "sepia vintage". |
providerSettings.bria.contentModeration | boolean | no | true | Apply content moderation to inputs and outputs. Always on: a false is sent as true. |
providerSettings.bria.edit | string | no | — | Editing workflow to apply. One of "colorize", "relight", "restore", "blend", "reseason", "sketch_to_image", "expand". |
providerSettings.bria.lightDirection | string | no | — | Direction of the light for the relight operation. One of "front", "side", "bottom", "top-down". |
providerSettings.bria.lightType | string | no | — | Type of lightning to apply in the relight operation. One of "midday", "blue hour light", "low-angle sunlight", "sunrise light", "spotlight on subject", "keep background settings", "overcast light", "soft overcast daylight lighting", "cloud-filtered lighting", "fog-diffused lighting", "moonlight lighting", "starlight lighting nighttime", "soft bokeh lighting", "harsh studio lighting keep background setting". |
providerSettings.bria.preserveAlpha | boolean | no | — | Enable alpha channel preservation in output. Only affects images that already contain an alpha channel. |
providerSettings.bria.promptContentModeration | boolean | no | true | Scan input prompt for restricted terms. Always on: a false is sent as true. |
providerSettings.bria.season | string | no | — | Target season for the reseason operation. One of "spring", "summer", "autumn", "winter". |
outputType | string | no | "URL" | Image output type. One of "URL". |
outputFormat | string | no | "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". |
outputQuality | integer | no | 95 | Compression quality of the output. Higher values preserve quality but increase file size. Documented range: 20 to 99. |
safety | object | no | — | |
safety.checkContent | boolean | no | — | Enable or disable content safety checking. Increases total generation time. Always on: a false is sent as true. |
advancedFeatures | object | no | — | |
advancedFeatures.watermark | object | no | — | |
advancedFeatures.watermark.text | string | no | — | Watermark text. Documented range: 2 to 32 characters. |
advancedFeatures.watermark.image | string | no | — | Watermark image (an http(s) URL; upload a local file first and send its read URL). A URL. |
advancedFeatures.watermark.displayPosition | string | no | — | 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.opacity | number | no | — | Watermark opacity. Documented range: 0.1 to 1. |
advancedFeatures.watermark.fontColor | string | no | — | Text color in hex format. |
advancedFeatures.watermark.bgColor | string | no | — | Background color in hex format. |
idempotency_key | string | no | — | 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.
