Gemini Omni Flash Video: Google's 4K Model, Priced Low

Short version: Google published Gemini Omni Flash video on 27 August 2026. Four resolution tiers from 360p to 4K, clips of 3 to 10 seconds, and a 360p tier at 20 cents for five seconds that makes it the cheapest way to test a shot on this shelf. Only two aspect ratios, which is its one real limitation.

This model is a day old. There is not yet a body of real-world output to judge it on, so what follows is the specification, the price, and where it sits, without pretending to more.

Disclosure: Leaxor is mine and now runs it.

What Google shipped

Gemini Omni Flash sits in the Gemini Flash line, which is Google's speed-and-cost tier rather than its flagship. The video endpoints arrived on fal on 27 August alongside image-to-video, reference-to-video and an edit mode.

Google announced the Omni Flash line in its own developer post. The specification is narrow and deliberate:

• Resolutions: 360p, 720p, 1080p, 4K. Default 720p.
• Duration: 3 to 10 seconds. Default 8.
• Aspect ratios: 16:9 and 9:16 only.

Two aspect ratios is unusually restrictive. Most models here offer five or six. If your work is landscape or vertical you will not notice; if you needed square, this model is simply not for you.

The price spread is the interesting part

Four tiers, and a ninefold gap between the cheapest and the dearest. That is a wider spread than any other model on the shelf.

Resolution	5 seconds	8 seconds	10 seconds
360p	2 credits ($0.20)	3 credits ($0.30)	4 credits ($0.40)
720p	6 credits ($0.60)	10 credits ($1.00)	12 credits ($1.20)
1080p	9 credits ($0.90)	14 credits ($1.40)	18 credits ($1.80)
4K	18 credits ($1.80)	28 credits ($2.80)	35 credits ($3.50)

Twenty cents for five seconds at 360p is the cheapest render available here. It looks like what it costs, and that is fine, because nobody publishes a draft. Use it to answer "does this framing work" across a dozen attempts for under three dollars, then spend once at the top.

Where it fits

Two genuine strengths. The 360p tier is the cheapest exploration on the shelf. The 4K tier exists at all, which is rare.

Two genuine limits. Ten seconds is short next to Wan 3.0's thirty. And two aspect ratios is two.

Against MiniMax H3 Max the shapes differ usefully: H3 Max is cheap in the middle and caps at 768p, Gemini is cheaper at the bottom and reaches far higher at the top.

Worth trying?

At twenty cents a draft, the question answers itself for anyone already generating video. Whether the 4K tier is worth $1.80 a clip depends entirely on whether anything downstream will ever display 4K, and for short-form social the answer is usually no.

Gemini Omni Flash and its image-to-video and reference modes are live in Leaxor's clip generator, priced per render, credits at $0.10 and no subscription. The full August wave is in the roundup, and every model's rate is in the cost breakdown.
