Gemini Omni Flash goes GA with 4K upscale — and preview endpoint shuts down 2026-09-30

2 sources

Google's Gemini API changelog indexed Gemini Omni Flash as GA on 2026-08-27 under the model id `gemini-omni-1.1-flash`. Three new capabilities are wired into the GA surface: continue an existing clip via an `extend` task or a prompt, generate a transition between two frames via `image_to_video` (up to 2 images), and pick a video resolution — 360p, 720p default, 1080p, or 4K — through a new `resolution` parameter in `video_config`. 1080p and 4K are produced via upscaling. The preview endpoint `gemini-omni-flash-preview` is deprecated and shuts down on 2026-09-30. Per-token pricing is not listed on the changelog entry.

Why now

Two actionable windows opened the same week: creators shipping short-form video tools have 33 days (2026-08-28 to 2026-09-30) to migrate from `gemini-omni-flash-preview` to `gemini-omni-1.1-flash`, and any creator who has been holding off on Omni-style video extension because it was preview-only now has a stable API surface to point at — and the resolution ladder plus the frame-interpolation task make the demo itself portable to short-form workflows.

Why it is worth publishing

Strong executable demo (frame interpolation between two stills) plus a concrete migration calendar. The 9/30 sunset is the editorial hook that turns this from a vendor blog post into a 'do this in the next four weeks' piece, and the resolution ladder is a chart creators can paste directly into their workflow docs.

Evidence basis

Official Gemini API changelog entry dated 2026-08-27 + Google blog index entry on the same date.

“Google's preview endpoint for Gemini Omni Flash shuts down on September 30 — if your short-form tool still points at the preview id, here's the four-week migration plan.”

Angle

Treat the 2026-09-30 preview endpoint sunset as the editorial anchor, not the GA itself. The capability set matters because every creator tool currently on the preview endpoint has to be ported in 33 days.

Short talking-head video

Demo idea

Show the migration in 90 seconds: search the codebase for `gemini-omni-flash-preview`, swap to `gemini-omni-1.1-flash`, set the new `resolution` parameter to 720p default (or 4K when the upload source supports it), and demonstrate first-and-last-frame interpolation between two stills via the `image_to_video` task with two images. Note on screen which capabilities were preview-only vs GA.

Platform notes

On screen, attribute the GA to the Gemini API changelog and quote the exact sunset date for the preview endpoint. Do not state a per-token price — the pricing page was not opened at capture time.

Usable claims

  • Google's Gemini API changelog indexes Gemini Omni Flash as generally available on 2026-08-27 under the model id `gemini-omni-1.1-flash`, with three new developer-facing capabilities: video extension via an `extend` task or prompt-driven continuation, interpolation between a first and last frame via `image_to_video` accepting up to two images, and a new `resolution` parameter in `video_config` supporting 360p, 720p (default), 1080p, and 4K outputs where 1080p and 4K are produced via upscaling.
  • The Gemini Omni Flash preview endpoint `gemini-omni-flash-preview` is deprecated and scheduled to be shut down on 2026-09-30. Applications calling the preview endpoint must migrate to the GA `gemini-omni-1.1-flash` before that date.
  • Per-token pricing for `gemini-omni-1.1-flash` is not stated on the Gemini API changelog entry. The changelog page directs readers to a separate pricing page and the model's own page for cost numbers; those pages were not opened at capture time, so the price-per-million-tokens figure is not cited in this topic.

Evidence pipeline

From the news

Breakdown

The Gemini API changelog indexes `gemini-omni-1.1-flash` as GA on 2026-08-27 with three capabilities (video extension, two-image interpolation, resolution control) and deprecates the preview endpoint `gemini-omni-flash-preview` with a 2026-09-30 shutdown. This breakdown separates the migration steps (model id swap, capability surface parity check, resolution ladder choice, upscaling caveat for 1080p/4K) from the editorial gaps (pricing is not on the changelog; reviewers should open the pricing page on camera rather than guess).

Risks

  • Before recording any demo, check the codebase for `gemini-omni-flash-preview` references. Plan the migration to `gemini-omni-1.1-flash` around the changelog's capability surface (extend task, image_to_video with two images, resolution parameter) rather than guessing parity. Open the changelog page on camera if you mention the date.
  • If the script needs a dollar figure, open the pricing page and the model page directly on camera, name the tier next to the number, and label the source. Avoid stating list price from memory.

Demo ideas

  • Frame-interpolation demo: two product stills as first/last frame, generate a 4K transition via upscale
  • Migration calendar: post a 4-week schedule — week 1 grep + audit, week 2 swap endpoint + run tests, week 3 cutover preview traffic, week 4 retire preview-only features
