Gemini Omni Flash goes GA with video extension, interpolation and 4K output controls

Google’s Gemini API release notes mark `gemini-omni-1.1-flash` generally available as of August 27, 2026. The GA release expands the model’s video generation and editing surface with three notable controls: video extension can generate a continuation at the end of an existing clip; interpolation can create a transition between a supplied first and last image; and a new resolution parameter supports 360p, 720p, 1080p and 4K output, with higher resolutions produced through upscaling. Google also set a September 30, 2026 shutdown date for the earlier `gemini-omni-flash-preview` endpoint.

For builders using generative video in product workflows, the meaningful shift is from an experimental endpoint to a supported migration target with additional editing operations. Video extension and endpoint-to-endpoint interpolation can reduce the need to stitch multiple specialized generation tools together, while resolution control makes the same API usable across preview, social and higher-resolution delivery paths. The September 30 cutoff means the change is also operational: preview users have a fixed deadline to test differences and move production integrations rather than treating GA as optional housekeeping.

Google’s release notes identify `gemini-omni-1.1-flash` as the generally available release. That gives teams a production target distinct from the earlier preview endpoint and makes version pinning more important for applications that need reproducible video output behavior.

The new `extend` task can create a continuation from the end of an existing clip. That supports workflows such as lengthening an approved shot, generating alternative endings or incrementally building longer assets without starting every iteration from the original prompt.

The image-to-video path can accept up to two images as endpoints and generate the transition between them. For creative tools, this creates a more controlled way to animate between known compositions than relying on one starting image plus an unconstrained prompt.

A `resolution` field supports 360p, 720p, 1080p and 4K. Google says 720p is the default and higher-resolution output uses upscaling. Builders should therefore distinguish output pixel dimensions from native generation detail when evaluating quality and cost.

Google says `gemini-omni-flash-preview` will be deprecated and shut down on September 30, 2026. Applications should test prompts, aspect ratios, editing behavior and output quality on `gemini-omni-1.1-flash` before switching rather than assuming the GA endpoint is byte-for-byte or behaviorally identical.
