Gemini Omni 1.1 Flash

What is Gemini Omni 1.1 Flash?

Gemini Omni 1.1 Flash is the generally available version of Google's Omni video model, and Google now tells Gemini API developers to use it as their default for video. It makes 3 to 10 second clips with sound from text, images or short videos, then changes them over follow-up prompts through the Interactions API while keeping what you did not mention. It replaces the preview model, which Google is deprecating, and Google says it is replacing Veo in the Gemini app.

Next to Veo 3.1, it is the better editor but the shorter storyteller: scenes stop at 40 seconds, and 1080p and 4K are upscaled from 720p.

What changed from the Gemini Omni Flash preview?

More control at the same price: longer scenes, first and last frames, video references and new resolutions.

Scene extension

Clips extend in 10-second steps to 40 seconds, and the model reads up to 10 seconds of earlier footage instead of only the final second.

First and last frames

New: give two images and it fills in the motion between them.

Resolution

The preview made 720p only; 1.1 adds 360p drafts and upscaled 1080p and 4K.

Status

1.1 is generally available on the paid Gemini API at the preview's prices, and Google is deprecating the preview endpoint.

Who is Gemini Omni 1.1 Flash best for?

Gemini Omni 1.1 Flash is best for developers building video apps with chat-style editing, creators stretching short clips into scenes of up to 40 seconds, and anyone who wants free promo clips in Google Vids.

• Video apps with chat editing

  Through the Interactions API you describe a change and the model edits the clip while keeping the parts you want.

• Longer scenes from short clips

  Clips of 3 to 10 seconds can be extended in 10-second steps up to 40 seconds, using up to 10 seconds of earlier footage for continuity.

• Cheap drafts before final renders

  360p previews come back up to 60% faster at about a third of the 720p cost, so you can try several ideas before paying for full resolution.

• Promo clips on no budget

  Google Vids lets anyone with a Google or Workspace account generate 1080p Omni clips at no cost, with templates for product launches.

What's included with Gemini Omni 1.1 Flash?

Chat-based editing, scene extension to 40 seconds, first and last frame control, video and image references, four resolutions up to 4K, and generated sound.

Conversational editing

Each follow-up prompt edits the previous clip, so you can swap objects, restyle a scene or change the camera angle without starting over.

Scene extension

Continues a clip from where it ends, reading up to 10 seconds of earlier footage, to a total of 40 seconds.

First and last frames

Give it two images and it generates the motion between them, for orbits, zooms or looping clips.

Video and image references

Up to 3 reference clips of 3 seconds each, plus reference images, keep a person, character or product consistent.

Four resolutions

360p for drafts, 720p by default, and 1080p or 4K through upscaling, in landscape 16:9 or portrait 9:16.

Generated sound

Clips come with speech, music and sound effects that follow the prompt, and every video carries Google's invisible SynthID watermark.

How does Gemini Omni 1.1 Flash work?

1. Draft

   Send a prompt, an image or a short clip to gemini-omni-1.1-flash and ask for 360p to try ideas cheaply.

2. Edit by chat

   Reply with the change you want, passing the previous interaction ID, and the model edits that clip.

3. Extend

   Ask it to continue the scene in 10-second steps until the story fits, up to 40 seconds.

4. Render

   Generate the version you keep at 720p, or at 1080p or 4K through upscaling.

How much does Gemini Omni 1.1 Flash cost?

Gemini Omni 1.1 Flash costs about $0.10 per second of 720p video on the paid Gemini API, is free within limits in Google Vids, and comes with Google AI plans from $4.99 a month in the Gemini app and Flow.

There is no free API tier for this model, and paid-tier prompts and videos are not used to improve Google's products. Video is billed at 5,792 output tokens per second of 720p; Google says 360p drafts cost about a third as much, and the pricing page gives no separate rate for 1080p or 4K. The preview model, gemini-omni-flash-preview, has the same prices. Outside the API, Google Vids lets anyone with a Google account generate Omni clips at no cost within usage limits, and Google AI Plus ($4.99 a month), Pro ($19.99) and Ultra (from $99.99) add video in the Gemini app plus 200, 1,000, or 10,000 to 25,000 Google Flow credits a month that work with Gemini Omni Flash.

Gemini Omni 1.1 Flash pros and cons

Its conversational editing is the reason to use it, but strict moderation, usage caps in Google's apps and weaker raw generation than Seedance or Kling are the common complaints.

What are the best Gemini Omni 1.1 Flash alternatives?

Veo 3.1 for longer scenes and native 4K, Seedance 2.5 for 30-second single takes, and LTX-2.5 for open weights and audio-driven video.

Veo 3.1Free

Choose it when you need scenes longer than 40 seconds, since it extends clips up to 148 seconds, or 4K generated directly rather than upscaled; its Fast tier costs the same $0.10 a second at 720p.

Seedance 2.5Paid

Choose it when raw generation matters more than editing and you want single takes of up to 30 seconds with reference audio; it costs about $0.23 a second at 720p.

LTX-2.5Free

Choose it when you want open weights you can run yourself or video driven by your own audio; its hosted API starts at $0.09 a second at 720p.
