Gemini Omni 1.1 Flash API and Pricing, Explained Through a Real Pipeline
Gemini Omni 1.1 Flash is Google's short-clip video model with sound on every render and a 360p tier at about 3.4 cents per second. Here is the rate card, what our first four renders measured, the one thing to know before you hand it a first frame, and how to reach it as a versioned API endpoint.
Gemini Omni 1.1 Flash is a video model from Google. It takes a prompt, and optionally a first and last frame, and returns a 3 to 10 second clip with an audio track in 16:9 or 9:16. It reached OpenRouter on 4 November 2026 and went onto Treza's canvas and into chat on 6 November.
Two things make it worth a look. It has a 360p tier at about 3.4 cents per second, a draft price the Veo 3.1 family does not offer. And it renders any whole second from 3 to 10, where Veo renders 4, 6 or 8. This post covers the rate card, what our first four renders measured, how the model treats a first frame, and how to call it as a published API endpoint. Every parameter and price is read off Treza's live video model catalog as of 6 November 2026, and the behavior was checked with real renders.

How Gemini Omni 1.1 Flash bills
Per second of output, at a rate set by the resolution. Audio is included at every tier:
| Resolution | Per second | 3 second clip | 5 second clip | 10 second clip |
|---|---|---|---|---|
| 360p | $0.0338 | $0.10 | $0.17 | $0.34 |
| 720p | $0.1014 | $0.30 | $0.51 | $1.01 |
| 1080p | $0.152 | $0.46 | $0.76 | $1.52 |
| 4K | $0.304 | $0.91 | $1.52 | $3.04 |
Those are the listed rates on the endpoint we run. One caveat on the 1080p row: the catalog lists that rate with no resolution label. It sits between 720p and 4K, and 4K is exactly twice it, so we read it as 1080p. We have rendered 360p and 720p only, so the 1080p and 4K rows are the listing and nothing more.
The steps are steep: 720p costs three times the 360p rate, and 4K nine times. That rewards drafting low. Settle the framing at 360p for 10 cents a take, then render the keeper once at the tier the placement needs.
For scale, at 720p with audio Veo 3.1 Fast lists $0.10 per second and Veo 3.1 Lite lists $0.05. So at 720p Gemini Omni 1.1 Flash costs about what Veo 3.1 Fast does and twice what Lite does. The price case for it is the 360p tier, which neither Veo model has. Rates across the catalog are collected in the AI video cost breakdown.
What four renders actually measured
Before a model goes in the picker we run it through the node's own request shape and read the bill. Here that was four 3 second clips. The text prompt asked for a barista pouring steamed milk into a latte in a sunlit cafe, with a slow push-in and natural ambient sound.
Text to video at 360p, vertical. Back in 29 seconds at 360 by 640 pixels, 24 frames per second, with an audio track. A steel pitcher pouring into a dark cup, latte art forming, cafe blurred behind. The charge was the listed 360p rate times three seconds, 10 cents.
Text to video with no resolution set, vertical. Back in 39 seconds at 720 by 1280, 24 frames per second. The same shot with visibly more detail: steam off the cup, an espresso machine in the background. It billed the 720p rate, 30 cents, which is how we know 720p is the default.
A first frame with an unrelated prompt, at 360p. The still was a product photo of a folded navy shirt on a wooden table. The prompt was the barista. The clip came back in 29 seconds at 640 by 360 and opened on a cafe, not on the shirt.
The same first frame with a matching prompt, at 360p. This time the prompt described sunlight drifting across a folded navy linen shirt on a light wooden table with a gentle push-in. The clip opened on the photo and moved in on the collar. 27 seconds, 640 by 360, 10 cents.
Every charge matched the listing to the cent, and a first frame did not change the rate.
A first frame only holds when the prompt describes it
That third render is the one to remember. The usual expectation of a first frame is that the clip opens on your still whatever the prompt says. Gemini Omni 1.1 Flash did not do that in our test. Handed a shirt and asked for a barista, it made the barista.
When the prompt described what was in the photo, the clip opened on the photo. So the working rule is: say what is in the image, then say how it moves. The Video Generation node carries a note for this model that says the same.
The first-frame renders also showed shape. Both came back 16:9: the node sends no aspect ratio when a frame is attached, and the model rendered landscape. For a vertical clip, start from a prompt, where 9:16 is a setting.
The technique itself is covered in the first frame post, and the image to video generator covers it from the still's side.
About the audio
Every clip came back with an audio track, and there is no silent rate to choose instead: the catalog lists only with-audio prices for this model.
In our four clips the track was a quiet ambient bed, well below normal listening level, even though the prompt asked for natural ambient sound. We have not tested prompts that ask for dialogue or music. Treat the built-in audio as room tone.
If a clip needs sound that carries, add it in the graph. A Text to Speech node handles narration, an Audio Generation node handles music or effects, and the Sequence node mixes them over the picture and can duck the clip's own audio under a voice.
What you actually pay on Treza
Gemini Omni 1.1 Flash through a Treza pipeline is metered from a prepaid credit balance. One credit equals $0.01, credit packs start at $5, credits never expire, and a failed generation charges nothing.
Before a run starts, the platform estimates the media cost of the graph and refuses to start one your balance cannot cover. For this model the estimate follows the resolution the node is set to, and uses the 720p rate when none is set, because that is what an unset clip renders and bills. A cheap draft means setting 360p on purpose.
Calling Gemini Omni 1.1 Flash as an API without building the integration
On a Treza AI video pipeline, Gemini Omni 1.1 Flash is a node on a canvas. Set the duration, aspect ratio and resolution, wire it next to a script step, a voiceover step or a captioning step, and publish the whole chain as one versioned endpoint. Your application calls a typed /invoke route with JSON in and JSON out, or points an existing OpenAI SDK at the OpenAI-compatible route.
The swap is what pays off later. A successor, Gemini Omni 1.2 Flash, is listed on OpenRouter as of 5 November 2026. We have no renders from it yet, so nothing here applies to it. When it or another model earns the slot, you change the dropdown and republish, and the endpoint your product calls does not change. Our hosted MCP server exposes the same pipelines as tools, so an agent in Claude or ChatGPT can render a brief and return the link.
Where Gemini Omni 1.1 Flash earns its place in a graph
Draft passes. Ten 3 second framings of one idea at 360p come to about a dollar of provider cost. Render the one that works once at 720p or above.
Odd-length shots. A 3 second cutaway, a 7 second product move, a 10 second establishing shot. Where another model makes you round up to 4, 6 or 8 seconds and trim, here the duration is the number you need.
Short vertical cuts. Text to video at 9:16 came back at 720 by 1280 in our test, with a quiet room tone under it that a voiceover can sit on. The Sequence node stitches up to 12 shots over one narration track.
To see what it costs for your own work, open the AI video generator, pick Gemini Omni 1.1 Flash, set the resolution to 360p, and generate once.
Frequently Asked Questions
How much does Gemini Omni 1.1 Flash cost per second?
$0.0338 per second at 360p, $0.1014 at 720p, $0.152 at 1080p and $0.304 at 4K, audio included, as listed on the endpoint we run on 6 November 2026. A 3 second 360p clip is 10 cents and a 10 second 720p clip is about $1.01. Our 360p and 720p test renders billed exactly the listed rate.
What resolution does Gemini Omni 1.1 Flash render?
360p, 720p, 1080p or 4K. With no resolution set it renders 720p, which came back as 720 by 1280 pixels at 24 frames per second for a vertical clip in our test. We have not rendered 1080p or 4K yet.
How long can a Gemini Omni 1.1 Flash clip be?
3 to 10 seconds in one generation, at any whole second. For longer pieces, stitch generations with the Sequence node, which handles up to 12 shots, or assemble them in the timeline editor.
Can Gemini Omni 1.1 Flash start from an image?
Yes, it takes a first frame. Describe what is in the image in your prompt. In our test the clip opened on the photo when the prompt matched it and cut to a new scene when the prompt was about something else. Both first-frame clips came back 16:9.
Does Gemini Omni 1.1 Flash generate audio?
Yes. Every clip carries an audio track and there is no cheaper silent rate. In our renders it was a quiet ambient bed. For narration or music, add a Text to Speech or Audio Generation node.
Is Gemini Omni 1.1 Flash cheaper than Veo 3.1?
At 720p with audio it lists about the same per-second rate as Veo 3.1 Fast and twice the rate of Veo 3.1 Lite. Its 360p tier is the cheaper option, at about 3.4 cents per second, and neither of those Veo models lists a tier below 720p.
Can I call Gemini Omni 1.1 Flash through an API without a Google Cloud account?
Yes. On a Treza pipeline, Gemini Omni 1.1 Flash is a node you configure once and publish as a versioned HTTP endpoint, with a typed /invoke route and an OpenAI-compatible route. You can also ask for it by name in Treza chat. Generations are metered from prepaid credits that start at $5 and never expire.
