Veo 3.1 Lite research now needs a provider-route check before a generation tutorial. Google’s official Gemini model page states that veo-3.1-lite-generate-preview shut down on October 22, 2026. It points users toward Gemini Omni Flash or GA models through the Gemini Enterprise Agent Platform. That statement concerns the named Gemini API preview endpoint; it does not establish that every Veo Lite offering in every product has disappeared.
Identify the route your workflow actually uses
Record the service, exact model ID, account and operation before replacing anything. A video model’s display name is not enough to identify its API endpoint. Keep a copy of the last known request structure and any completed output files so the migration has a concrete baseline.
Google’s deprecation reference distinguishes a deprecation notice from a shut-down endpoint. Use the explicit status of the model you are calling rather than a search snippet, old pricing table or historical model card. The linked preview page provides a specific shutdown statement.
Separate candidate replacements from a verified migration
The current Gemini Omni Flash model page identifies gemini-omni-1.1-flash as stable and documents video creation and editing. Its workflow is not proof that an old Veo request can be migrated by replacing one string. Check the current API operation, supported inputs, duration and output handling for the selected destination.
If you choose a GA Veo route through Google’s enterprise platform, verify that route’s exact model and authenticated availability separately. Do not reuse a Gemini preview identifier as if it named the same operation everywhere. This guide does not submit either route or claim account entitlement.
Keep the shot brief when the endpoint changes
Our original fictional brief is one miniature blue sailboat on a calm studio water tray, warm light and a gentle forward camera move. The important acceptance criteria are the hull shape, sail arrangement, controlled movement and usable beginning and ending. Those creative decisions can survive a migration even when technical controls change.
One original miniature blue sailboat on a calm studio water tray. Warm light and a gentle forward camera move. Preserve the hull shape and sail arrangement throughout the shot. No text or logos. Review the complete returned motion and any audio before accepting the clip.
This brief is unexecuted. The separate cover is conceptual artwork, not a generated Veo or Omni clip and not the first frame of a tested sequence. Choose a duration supported by the actual destination rather than turning an old request’s length into an assumed replacement capability.
Inventory the migration before making a new request
Download the original migration plan and blank review worksheet. The plan identifies the retired preview route and candidate destinations, while leaving the selected replacement, account verification, quote and output unset. It is a planning manifest rather than an executable API request.
| Decision | Evidence to record | Why it matters |
|---|---|---|
| Provider route | Actual service and model ID | A similar display name can hide a different endpoint |
| Inputs | Text image or video operation actually supported | An old reference input may not map directly |
| Controls | Allowed duration dimensions and audio behavior | Old parameters should not be copied without checking |
| Cost | Current authenticated quote for the actual settings | A historical model price does not establish this job’s cost |
| Delivery | Downloaded file and completed operation record | A successful request response is not the finished media |
Submit one controlled test after route verification
Begin with one short shot whose success you can describe. Avoid changing the story, reference, format and provider at the same time. Record the actual settings and operation ID. If a request times out, inspect that operation before submitting another paid generation; an observation failure does not prove that processing stopped.
Keep application integration and creative approval separate. The new route may produce a technically valid file while changing the boat or giving it unwanted motion. Conversely, a strong clip still needs correct file handling and a predictable completion path before an automated workflow can rely on it.
Review the whole output and its audio
Watch the full take for changes to the hull, mast, sails and water contact. Inspect the first and last usable frames. Listen to any returned audio and decide whether it belongs in the intended edit. Do not assume that a general model-family audio description proves the selected operation returns the track you need.
Record actual dimensions, duration, audio presence and accepted interval from the downloaded file. The worksheet’s observations remain empty and not run; this guide supplies no measured generation time, quality comparison or cost saving. An end-to-end migration is proven only when the chosen route and final media both meet the job’s requirements.
Continue with the right production guide
For planning several shots, use the multi-shot AI video workflow. For a local-first model route, see the Phosphene preparation guide. Explore Clout Image and Video for available operations; this is an alternative route, not a claim that the retired preview endpoint is offered there.
