gemini-omni-flash-preview shuts down September 30: what to change

If your code calls gemini-omni-flash-preview on the Gemini API, it stops working on September 30, 2026: Google's deprecations page lists that date and recommends gemini-omni-1.1-flash, released August 27, 2026, with no shutdown date announced. Change the model code, then re-test edits and extensions. On Sume the video model is gemini-omni-flash-1.1; you send Sume's own id to Sume, not Google's model code.

Dates are from Google's deprecations page and Omni page, read 2026-09-29.

Which Omni model codes are affected?

What does Omni Flash do that I should re-test?

Google's Omni page describes text, image and reference-to-video, stateful multi-turn editing with previous_interaction_id, editing uploaded videos, and extension that appends a 3 to 10 second continuation. Limits it lists: video references up to 3 clips of up to 3 seconds each, audio references unsupported, and editing or extending uploaded videos is not available in the EEA, Switzerland and the UK. Re-run your edit and extension prompts after the switch.

What is the Sume id and what does it accept?

Sume lists gemini-omni-flash-1.1: 3 to 10 seconds at 360p, 720p, 1080p or 4K in 16:9 or 9:16, native synced audio, image and video input_references (no audio), and video edit through the Video Router video_url field. Sume's pricing code estimates a 5-second clip at $0.63 at 720p, $0.94 at 1080p and $1.88 at 4K; the catalog is the live source.
