Sora 2 vs Gemini Omni Flash: Fast Drafts After Sora
Sora 2 (retired) → Gemini Omni Flash
Quick Answer
OpenAI shut the Sora API down on September 24, 2026. Gemini Omni Flash, a Google preview engine, covers one Sora job well: fast drafts. It renders native audio in the same step and keeps exact likeness from your scene image, but it is 720p only with 4–10 second clips, so ship final ads on Veo 3.1, Kling 3.0, or Seedance.
Side-by-side comparison
| Feature | Sora 2 | Gemini Omni Flash |
|---|---|---|
| Status | Retired Sep 24, 2026 | Preview |
| Max resolution | 1080p (HQ tier) | 720p only (no HQ) |
| Native audio | No | Yes |
| Clip length | 4–20s | 4–10s |
| Face likeness | Approximate (rebuilt from text) | Exact (scene image as start frame) |
| Strongest at | Lowest-cost faceless ads | Fast native-audio drafts |
| 3-scene 24s ad (std) | Retired | 120 cr |

| Per-second cost (std) | Retired | ~5.0 cr/s |
What Sora 2 was used for
- The lowest cost per second for faceless product shots
- A 1080p HQ option for hero renders
- Stable, generally available rendering (it was never a preview)
Sora 2 was retired on Sep 24, 2026, when OpenAI shut its API down. It can no longer be selected; API requests that still name it render on Seedance (or on Kling when the request includes a scene image and is not faceless).
Why Gemini Omni Flash replaces it
- You want quick drafts with native audio rendered in the same step
- You want exact likeness from your scene image
- 720p is fine for testing hooks before you render the final ad on Veo 3.1, Kling 3.0, or Seedance
Frequently Asked Questions
The Verdict
Gemini Omni Flash covers Sora 2's draft role with native audio and exact likeness, but it is a 720p preview engine. Draft on Omni if you like its speed, then ship on Seedance (the closest Sora match), Veo 3.1, or Kling 3.0.
