Google retires Veo 3.1 preview endpoints in Gemini API, points users to Gemini Omni

What happened

The three affected model IDs are:

• veo-3.1-generate-preview
• veo-3.1-fast-generate-preview
• veo-3.1-lite-generate-preview

Google names gemini-omni-1.2-flash as the recommended replacement for all three.

A second change follows. gemini-omni-1.1-flash has an earliest shutdown date of December 3, 2026. From then, requests are set to route automatically to Omni 1.2 Flash.

Google says these are the earliest possible dates and that exact dates are communicated in advance.

The change covers preview IDs in the Gemini API. Generally available Veo 3.1 models remain on Google Cloud enterprise platforms, per Everypixel Journal.

Why it matters for creators

Developers and tools built on Veo preview IDs must migrate. The move is also a sign that Google is consolidating its video line under the Gemini Omni brand.

For most creators, the change is invisible unless a tool they use was calling the Veo 3.1 preview IDs directly. For developers, the practical steps are to move those calls to gemini-omni-1.2-flash, and to note that gemini-omni-1.1-flash requests are set to be routed to Omni 1.2 Flash from December 3 at the earliest.
