Grok Imagine Video 1.5

$0.0450 per second of videovideo.grok

Generate a video from a text prompt using xAI Grok Imagine Video 1.5 at 720p with synchronized audio, or animate a still image you supply.

Clips run 1 to 15 seconds. 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.

What a call costs

Billed on the exact size of your request, minimum $0.0020 per call.

a price before every call. failed calls are never charged.

When to use it

Use when you need motion cheaply or at volume: drafts, moving backgrounds, quick social clips, or ten takes on an idea before committing to an expensive model. The cheapest video model in the catalog, and it animates a photograph at the same rate as it films a prompt. To send 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. Billed per second of video you ask for.

Inputs

Grok Imagine Video 1.5 takes 7 fields, 1 of them required. Anything you leave out falls back to the tool's own default.

Field	Type	Required	What it does
prompt	string	yes	What to film. Describe the subject, the action, the camera move and the timing; sound is generated to match.
duration	integer	optional	Length of the generated video in seconds. This is what you are billed on, and it is the only field that changes the price.
image_urls	array of string	optional	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	string	optional	Fixed at 720p. Resolution changes the price per second, and this endpoint quotes one exact rate, so 480p would get its own endpoint.
aspect_ratio	string	optional	Shape of the output video. Ignored when a starting image is supplied, which decides it.
image_base64	string	optional	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	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.
