`resolution`	Per video	Google’s price for 10 seconds
`360p`	$0.10	$0.23
`720p` (default)	$0.30	$0.70
`1080p`	$0.45	$1.04

A 10-second clip costs about 43% of Google’s list price. Google bills per second; its prices come from the Gemini API pricing page, checked on November 11, 2026.
Adding images does not change the price.
Failed tasks are refunded in full, and requests rejected at submission are not charged.
For the full billing rules, see Pricing in the Gemini Omni guide.

Who is affected

If you want to call Gemini Omni: your existing default-group token works. You do not need a Google account or a new token group.
Tokens set to Usage-based only: they cannot call this model. Switch the billing mode to Usage first or Per-call.
Other video models: prices and requests for Muse, MiniMax H3, Wan, and Seedance are unchanged.

FAQ

What is the model ID for Gemini Omni 1.2 Flash?

gemini-omni-1.2-flash, called through POST /v1/videos.

Do I need a Google account or a Gemini API key?

No. A LaoZhang API token in the default group is enough. Use the Usage first billing mode.

How long does one video take?

A short 360p clip usually takes 30–60 seconds, a 10-second 720p clip about a minute, and a 10-second 1080p clip about 1.5–2 minutes. The API is asynchronous, so the create and status requests return right away.

No. Clips are 3–10 seconds at up to 1080p. For continuous 20–60 second clips use Muse; for 2K use MiniMax H3.

Are the videos watermarked?

There is no visible watermark. Each file carries Google’s C2PA content credentials and an invisible SynthID watermark that mark it as AI-generated.
