Google’s Gemini API deprecations page, last updated 2026-10-07 UTC, lists gemini-omni-flash-preview and three Veo 3.1 preview identifiers for shutdown on October 22, 2026, each with gemini-omni-1.1-flash as the replacement. The page defines a deprecation as the announcement that support is no longer provided and that the model will be shut down. After shutdown, the endpoint is completely turned off and no longer available.
Who this affects
- For counsel/compliance: Callers of gemini-omni-flash-preview, veo-3.1-lite-generate-preview, veo-3.1-generate-preview, and veo-3.1-fast-generate-preview have a documented shutdown date of October 22, 2026, after which the page states the endpoint is no longer available.
- For investors: The page maps all four preview identifiers to one replacement, gemini-omni-1.1-flash, listed as released August 27, 2026, with no shutdown date announced.
The read
Four preview identifiers share one shutdown date and one named successor. gemini-omni-flash-preview was released June 30, 2026. veo-3.1-lite-generate-preview was released March 31, 2026. veo-3.1-generate-preview and veo-3.1-fast-generate-preview were released October 15, 2025. On the same page, older Veo rows name veo-3.1-generate-preview, or GA models on the Gemini Enterprise Agent Platform, as a replacement. The Veo 3.1 preview rows themselves name gemini-omni-1.1-flash. The documented pattern is a single October 22 cutover of these preview endpoints onto that GA model, not four separate successors.
What was the action?
The Gemini deprecations page records these models as preview models with a shutdown date. A deprecation, in the page’s wording, is the announcement that support is no longer provided and that the model will be shut down in the near future.
What’s the penalty / scope, and how is it set?
No penalty is stated. The action is a shutdown of four preview model identifiers on October 22, 2026: gemini-omni-flash-preview, veo-3.1-lite-generate-preview, veo-3.1-generate-preview, and veo-3.1-fast-generate-preview. Each row names gemini-omni-1.1-flash as the replacement. The page states that once a model is shutdown, it is completely turned off and the endpoint is no longer available.
Who else is exposed?
Not specified in the record beyond developers using those Gemini API preview model identifiers. gemini-omni-1.1-flash is listed as the replacement, released August 27, 2026, with no shutdown date announced.
What happens next
The shutdown date on the page is October 22, 2026. The open item is migration off the four preview identifiers to the named replacement, gemini-omni-1.1-flash, before that date. No further deadline is stated.
