Gemini Omni Flash 1.1: what a 10-second 4K clip costs on Sume

A 10-second Gemini Omni Flash 1.1 clip at 4K costs $3.75 through Sume: $0.30 per second provider list, times 1.25, times 10 seconds. The same clip is $1.875 at 1080p, $1.25 at 720p and $0.375 at 360p. Ten seconds is the longest the model accepts.

The Sume catalog id is gemini-omni-flash-1.1. It accepts 3 to 10 seconds in 16:9 or 9:16, at 360p, 720p, 1080p or 4K, with native synced audio that is always on. All values are as of 2026-10-08.

What the vendor says

The fal page for the text-to-video endpoint describes Gemini Omni Flash 1.1 as Google's multimodal video model that generates video with synchronized native audio from a text prompt, grounded in Gemini's real-world knowledge and physics understanding (fal page, read 2026-10-08). Google's Gemini API video page lists Gemini Omni Flash as a fast, multimodal model for video generation and conversational video editing (Google page, read 2026-10-08).

Default and the 4K token

If you send no resolution, the catalog default is 720p, and the default duration is 8 seconds: 8 x $0.125 = $1.00, which is the value Sume's own fixture reserves for a bare prompt. Send 4K in the catalog; the code accepts lowercase 4k as an alias and sends the right string to the provider.

4K is exactly twice the 1080p rate and three times the 720p rate, so use it only for the final render. A cheap workflow drafts at 360p ($0.0375 per second) and then repeats the prompt at 1080p or 4K.

Budget examples

Ten 10-second clips at 4K cost 10 x $3.75 = $37.50. The same ten clips drafted at 360p cost 10 x $0.375 = $3.75, and finishing the three best at 4K adds 3 x $3.75 = $11.25, for a total of $15.00 instead of $37.50. Drafting low and finishing high is the cheapest way to use the 4K tier.

Because the reserve at submit is the provider list times 1.25, make sure your workspace balance covers the full 4K reserve for a 10-second clip, which is $3.75, before you start a batch.

Limits

• No generate_audio toggle: audio is always on and the API rejects false.
• Aspect ratio: 16:9 or 9:16 only.
• Prompt: up to 20,000 characters.
• No bitrate_mode and no reference audio.
• Cost is the provider list x 1.25 for each output second, as a function of the resolution.
