Running a model
GoogleText to videoGoogle Gemini Omni Flash
Multimodal video generation and editing with native audio, multi-turn control, and photo-to-video references
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-video · Scope video:write (or external:write on an older key) · Price Credits per megapixel-second (counted as width*height*floor:0.9036*duration): 13.0508. width*height counts as at least 0.9036 megapixels. From 4.608 to 16.384 megapixel-seconds a request. Priced up to height 1280, width 1280; past that a request is refused before any charge. Plus 0.360825 credits per input image (counted as items:inputs.referenceImages+inputs.frameImages), up to 8 input images. Plus 256.435734 credits when the request sends inputs.video (counted as any:inputs.video). Plus 0.000236 credits per token of input (counted as bytes:positivePrompt, one token at most per UTF-8 byte), up to 1048576 tokens of input. An MP4 or MOV clip in inputs.video that you uploaded through POST /v1/uploads, that one of your jobs made on a catalogue model or an auray-ai/ model, or that is a file of a Cinema Studio project you can open, is held for its own length instead, where its length can be read from the file: 25.643573 credits for each second it runs, rounded up to the next whole second, up to 10 seconds. A request that sends it and no duration counts none of duration: its band at its least. Any other clip — a WebM, a file whose length cannot be read, a clip sent by any other link, or one that runs past 10 seconds — is refused before any charge. 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.
#What it can do

- Aspect ratios: 16:9, 9:16

Find the addresses that do any of these with GET /v1/models?operation=<id>; the openapi.json carries them as data under x-auray-capability.
#Input
| Field | Type | Required | Default | Description |
|---|---|---|---|---|
inputs | object | no | — | |
inputs.referenceImages | string[] | no | — | List of reference images (an http(s) URL). Documented range: 1 to 7. When the request also sends inputs.video, this model makes the person in a picture here speak or move: a picture you upload, or a link from anywhere else, is taken once your account has accepted, one time, that you have the right to the faces and voices you use — send acceptance: {"real_people": "2026-11-03"} with the request, or accept in the Auray app — and is refused 403 acceptance_required until then, before anything is charged. A picture made here — a job's result — asks nothing. While uploads are paused here, a picture you upload, or a link from anywhere else, is refused 403 likeness_not_made_here instead, before anything is charged. The files the examples here send are ours, and are taken. |
inputs.frameImages | string[] | no | — | Images that pin frames of the video, as a list of image URLs: one image is the first frame, two are the first and the last, and three or more anchor the first and the last with the rest spread evenly between. Each item is a plain URL; the object form that names a frame or a timestamp is not accepted here. Documented range: 1 to 1. |
inputs.video | string | no | — | Video input (an http(s) URL; upload a local file first and send its read URL). Source video to be edited. A URL. |
positivePrompt | string | yes | — | Text prompt describing elements to include in the generated output. The output aspect ratio (16:9, 9:16) and duration can also be given in the prompt as an alternative to the width/height and duration parameters. Documented range: 2 or more characters. |
width | integer | no | 1280 | Width of the generated media in pixels. One of 1280, 720. |
height | integer | no | 720 | Height of the generated media in pixels. One of 720, 1280. |
duration | integer | no | — | Length of the generated video in seconds. The total number of frames produced is determined by duration multiplied by the model's frame rate (fps). Documented range: 3 to 10. |
settings | object | no | — | |
settings.temperature | number | no | 1 | Controls randomness in generation. Lower values produce more deterministic outputs, higher values increase variation and creativity. Documented range: 0 to 2. |
settings.topP | number | no | 0.95 | Nucleus sampling parameter that controls diversity by limiting the probability mass. Lower values make outputs more focused, higher values increase diversity. Documented range: 0 to 1. |
outputType | string | no | "URL" | Video output type. One of "URL". |
outputFormat | string | no | "MP4" | 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 "MP4", "WEBM", "MOV". |
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. |
safety.mode | string | no | "fast" | Safety checking mode for video generation. Only fast or full is sent here: any other value is sent as fast. |
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. |
acceptance | object | no | — | Your account's one acceptance, sent with the request that first needs it: a file of a real person's face or voice you upload, in a field this model makes speak or move, copies the voice of or puts into a clip, is taken once your account has accepted, one time, that you have the right to the faces and voices you use. Kept for your account before anything is charged, so no later request asks again — in any app or through the API — and asked of no file made here. You can accept in the Auray app (Account → Privacy) instead; an assistant cannot accept for you, so through MCP it is accepted in the app. |
acceptance.real_people | string | no | — | The version of the words you accept: that you have the right to every face and voice you upload, and to any voice or style you pick that sounds like a real person — it is yours, or you have permission — and that you are responsible for what you make with them. One of "2026-11-03". |
