Alongside its release on developer platforms, Nano Banana 2 Lite is also coming to Google consumer surfaces including AI Mode in Search, Gemini app, NotebookLM, Google Photos, Stitch, Google Flow, and Google Ads.
Experience high-quality, cost-efficient video editing and generation with Gemini Omni Flash
Watch as someone uses Gemini Omni to perform four digital magic tricks, like pulling a 3D balloon word out of her phone and pouring water from the screen into a glass. There is a small “original" video in the corner revealing how she actually filmed the tricks before the Omni generated special effects were added.
At Google I/O we introduced Gemini Omni Flash, the model where Gemini’s multimodal reasoning meets video generation and editing. Today, Gemini Omni Flash (gemini-omni-flash-preview) is rolling to developers via the Gemini API and Google AI Studio, natively supporting high-quality video generation and conversational editing from a combination of text, image and video inputs. This model is priced competitively at $0.10 per second of video output, which is the same as Veo 3.1 Fast.
Omni Flash shines in:
- Conversational video editing: Refine and edit videos using natural language.
- Multimodal referencing: Combine inputs like images, text and video to maintain control and consistency over your scene.
- Real-world knowledge: Omni draws on Gemini’s knowledge such as history, biology and narrative logic to construct compelling videos.
- Text and action synchronization: Connect text and graphics directly to video actions, through simple prompting.
For comprehensive benchmarking information, please visit Google DeepMind's Gemini Omni webpage.
Limitations:
- Omni offers 10-second video generations currently, with longer durations coming soon.
- Uploading audio references and scene extension is not yet supported in the Gemini API for this model.
- Video references up to 3 seconds in duration are accepted by the API schema but are not correctly processed by the model at this time.
- Character consistency when changing scenes or panning movements has some limitations but we are working to make this better.
Gemini Omni is available in public preview starting today in Google AI Studio and the Gemini API. To see the full list of model capabilities and regional specific limitations check out the developer docs.
Build with both models today
The real magic happens when you chain these models together. Use Nano Banana 2 Lite as a high-speed image generation model, then pass that image as a reference to Gemini Omni Flash to animate it into a high-quality video. Plus, by using the Interactions API for these multi-turn experiences, you can maintain session history and context so users can stack up to three sequential edits.
To help you get started we created a few demo apps you can remix that let you experience how you can pair both Nano Banana 2 Lite and Gemini Omni Flash into one workflow.
Anywhere is a demo app built to showcase the strong capabilities of both models. Take a selfie or upload a photo, and the app uses Nano Banana 2 Lite to instantly transport you to dozens of iconic landmarks. Then, when an image is clicked, Omni Flash is used to turn the generated image into an animated clip of the location.
Space Lift is a demo interior design app powered by Nano Banana 2 Lite and Gemini Omni, that lets you instantly reimagine any room by uploading a photo. The app automatically generates fully realized concepts across various design aesthetics. Once you find a look you love, tap the video button to watch Omni bring the design to life with a cinematic showcase, letting you experience your new space in motion before making it a reality.
Omni product studio is a demo app that converts static images created by Nano Banana 2 Lite into cinematic e-commerce videos created by Gemini Omni. This demo illustrates building interactive media by merging multimodal inputs through quick interaction with an image-to-video output.
