Gemini Omni 1.1 Flash

Google's fast multimodal video generation and editing model with native audio, using the Interactions API. Text-to-video, image-to-video, keyframe interpolation, reference-to-video, and video editing at 360p-4K.

3240 credits

per 10s 720p video — billed per output second (360p 116/s, 720p 349/s, 1080p 535/s, 4K 1046/s); edit mode bills the source video's length

Native synchronized audio on every video — dialogue, sound effects, ambient sound

Video editing: describe the change in the prompt and the rest of the video is preserved

Keyframe interpolation between a start and end frame — orbits, zooms, timelapses, seamless loops

Reference images guide subject and style without being used as literal frames

360p fast-draft mode up to 4K final output, 16:9 or 9:16

Quick Start

curl -X POST "https://api.core.today/v1/predictions" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: cdt_your_api_key" \
  -d '{
  "model": "google/gemini-omni-1.1",
  "input": {
    "prompt": "A cinematic drone shot through misty pine mountains at sunrise, gentle wind and birdsong. No dialogue.",
    "resolution": "720p",
    "aspect_ratio": "16:9"
  }
}'

Parameters

Parameter	Type	Required	Default	Description
`prompt`	string	Yes	-	Text prompt describing the video — scene, camera movement, lighting, mood, and audio. Put anything to avoid in the prompt too (e.g. 'no dialogue')
`image`	string	No	-	Starting image to animate into a video. When provided without last_frame, the video is generated from this image
`last_frame`	string	No	-	Ending image. Together with image, the model interpolates a smooth transition between the two frames
`reference_images`	array	No	[]	Reference images that guide the subject and style (not used as literal frames) — e.g. specific characters or objects
`video`	string	No	-	An existing video to edit. Describe the change in the prompt; the model preserves the rest. Billing uses the source video's measured length
`resolution`	string	No	720p	Output resolution. 360p is a fast draft mode. Billing per output second: 360p 116, 720p 349, 1080p 535, 4k 1046 credits 360p720p1080p4k
`aspect_ratio`	string	No	16:9	Video aspect ratio. Ignored when editing an existing video 16:99:16

How to Provide File Input

There are 3 ways to provide files for the imagelast_framereference_imagesvideo parameters:

Recommended

Image URL

Pass a publicly accessible URL directly. With the Storage API (POST /v1/files/upload-url) the file uploads straight to S3 (50MB per file) and you pass the returned file_url.

{
  "model": "google/gemini-omni-1.1",
  "input": {
    "prompt": "your prompt here",
    "image": "https://example.com/image.jpg"
  }
}

Direct Upload (Multipart)

Attach files directly to POST /v1/predictions/upload. No separate upload step, but the bytes pass through the API server so the whole request is capped at 10MB.

curl -X POST "https://api.core.today/v1/predictions/upload" \
  -H "X-API-Key: cdt_your_api_key" \
  -F "model=google/gemini-omni-1.1" \
  -F 'input={"prompt":"your prompt here"}' \
  -F "file:image=@your_file.png"

See the File Upload docs for more upload methods including Presigned URLs.

Common Parameters

Common parameters used when calling POST /v1/predictions.

Parameter	Type	Required	Default	Description
`model`	string	Yes	-	Model identifier
`input`	object	Yes	-	Object containing the model-specific parameters from the table above
`output_folder`	string	No	-	Folder path for output files (max 256 chars, '..' not allowed)
`webhook_url`	string	No	-	Webhook URL to call on completion
`is_public`	boolean	No	false	If true, output files are also available via permanent public URLs
