Gemini Omni 1.1 Flash video

Generate a 4, 6, 8 or 10 second video at 1080p from a text prompt using Google Gemini Omni 1.1 Flash, or animate a still image you supply as the first frame. Priced per video by its length. Returns the URL of the generated MP4. That URL is temporary: Goro holds a run’s results for 24 hours and nothing guarantees the file outlives that, so collect what you need within 24 hours.

Use when you want Google’s video model with a fixed, known price per clip rather than a per-second meter: explainer shots, product reveals, short social clips where the brief fits in ten seconds. Strong prompt adherence and clean 1080p output. To animate a local or private image, upload it first (POST /v1/uploads, or create_upload over MCP, or goro run —image) and pass the handle as image_handle. The price is exact once you pick the duration.

Price

$1.05 per call at `8`.** A flat price, and the only thing that changes it is `duration`: `4` costs **$ 0.63, 6 costs $0.84**, `8` costs **$ 1.05, 10 costs $1.26. Every one of those is exact and known before the call, so the hold and the charge are the same number and there is no ceiling to reconcile. Omit duration and you are billed the 8 price. A call that fails, times out or is stopped releases its hold in full and costs nothing.

Input

Field	Type	Required	Notes
`prompt`	`string`	yes	What to film. Describe the visual content, style, cinematography and any character actions.
`duration`	`4`, `6`, `8`, `10`		Length of the generated video in seconds, one of 4, 6, 8 or 10. This is the only field that changes the price: $0.63,$ 0.84, $1.05 or$ 1.26 per video. Defaults to `8`.
`image_urls`	`array`		Optional. One public http or https link to the image the video should start from (JPEG, PNG or WEBP, up to 10 MB). Use this when the image is ALREADY published somewhere; the output URL of an image endpoint works directly. Nothing is copied or re-hosted, we pass the link on. For a file that is not already public, use image_handle instead and it never has to be published anywhere. Send one of the three, never two.
`resolution`	`1080p`		Fixed at 1080p, which costs the same as 360p and 720p on this model; 4k is a different price and would get its own endpoint. Defaults to `"1080p"`.
`aspect_ratio`	`16:9`, `9:16`		Shape of the output video. 16:9 for landscape, 9:16 for vertical. Defaults to `"16:9"`.
`image_base64`	`string`		Optional, and only for a SMALL image (under 3 MB) or a caller that cannot run a shell command. The image inline, as base64 of the file’s own bytes; a data:image/png;base64, prefix is accepted and its declared type ignored. Understand the cost before choosing it: this string is part of the request, and on an MCP call the request IS the tool arguments, which pass through the model’s context window. A 3 MB photograph is 4 MB of base64, on the order of a million tokens, and in practice it is truncated and the run fails looking like file corruption. Do not downscale an image to fit here: use image_handle, which takes up to 10 MB and keeps the file out of the conversation entirely. The 3 MB ceiling is 4,194,304 base64 characters and is a property of the request body, not of the model. JPEG, PNG or WEBP, checked against the file’s own leading bytes rather than against any type you declare. Send one of the three, never two.
`image_handle`	`string`		Optional, and the RIGHT WAY to send a local or private image. Upload the file first with POST /v1/uploads (or the create_upload MCP tool, or the CLI’s —image flag, which does the whole thing for you) and put the short handle it returns here. The file goes straight from you to a private bucket: it never passes through a tool call, so it never passes through a model’s context window, and up to 10 MB is fine. Nothing is published. The handle is usable for 10 minutes after the upload lands and the file is deleted 30 minutes after that. Supplying it makes this an image-to-video call, at exactly the same price. Send one of image_handle, image_urls and image_base64, never two.

These are all the fields this endpoint accepts. Anything else is rejected as a validation_error rather than forwarded to the provider.
