## Which one, for what

### Gemini Omni 1.2 Flash (C)

Good for: Short product, ad and explainer clips with audio where an agent needs to revise a clip over several turns rather than regenerate it.

Ahead on:
- Reliability, 45 against 35
- Schema & documentation, 69 against 48
- Security & auth, 50 against 28
- Maintenance & community, 83 against 47
- Transparency & trust, 72 against 46

Watch for: No free tier, per the pricing page

### Vidu API (E)

Good for: Batch jobs that can wait for off-peak prices and want reference-to-video or start-end frames with sound.

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine

Watch for: No llms.txt, OpenAPI file or error-code reference


## Why the edge

### Maintenance & community: Gemini Omni 1.2 Flash +36

- Gemini Omni 1.2 Flash (83): Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Released and generally available on 5 November 2026; the SDKs added it to the Interactions model list on 10 November (30). Deprecations with earliest dates and no stated minimum notice (4 of 12). Churn in Google's video line: every Veo model on the Gemini API shut down by 22 October, and from 3 December 2026 requests to Omni 1.1 Flash are routed to 1.2 Flash and billed at its rates, four weeks after this release (4 of 8). Dated SDK and platform changelogs (15). SDK replies not sampled (5 of 10). Current SDKs in five languages (15). Runtimes stated (10). 30 + 4 + 4 + 15 + 5 + 15 + 10 = 83.
- Vidu API (47): Model reading. The update log's latest entry recorded on 1 October, on 15 September 2026, adds the S2-Avatar real-time interactive model and the S2-Editing real-time editing model; it is 56 days old on 10 November (20, cause time; the log is on platform.vidu.com, unread on 10 November because its robots.txt redirects to the home page, so a newer entry can't be seen). Q1 and Q2 stay callable, no removals found, no policy (10). Dated update page and support by email (12). No official SDK. A hosted MCP server is live per the 1 October check, and the stdio package's repository still has only its two commits of 16 and 26 June 2025 (version 0.1.2, no tags) (5). No recent release or CI on the MCP repository (0). 20 + 10 + 12 + 5 + 0 = 47.

### Transparency & trust: Gemini Omni 1.2 Flash +26

- Gemini Omni 1.2 Flash (72): Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Closed service with clear terms, SDKs Apache-2.0 (15). Paid only, so content isn't used to improve products; video retention isn't stated (20 of 30). Deprecations table and a dated routing notice for Omni 1.1 Flash (15 of 20). Data may be processed anywhere Google has facilities on the Gemini API route; no subprocessor list checked (5 of 20). SynthID watermarking is disclosed, and Google names the cases it still handles poorly. 15 + 20 + 15 + 5 = 55.
- Vidu API (46): Closed models under terms with ShengShu AI HK Limited and Hong Kong law. The terms don't restrict commercial use and forbid removing the AI-generated label, but don't say who owns the output (12). The terms let ShengShu record and use inputs and outputs for operational and other purposes, with no retention periods, and we didn't read the privacy policy against them (5). No deprecation policy (0). No subprocessor list or data locations found (0). Per the 1 October check, not re-read on 10 November (platform.vidu.com answered robots.txt with a redirect to its home page, so the host is left unread).

### Security & auth: Gemini Omni 1.2 Flash +22

- Gemini Omni 1.2 Flash (50): Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Keys bound to a service account and restricted to the Gemini API, with no scopes and a token accepted in the URL (15 of 30, the platform's deduction). The pricing page, read on 11 November, lists no free tier for Omni 1.2 Flash, and paid-tier content isn't used to improve Google's products (15 of 20). Retention of generated videos isn't stated in the guide (5 of 15). Request logs described for Generate Content, not confirmed for Interactions video calls (10 of 15). security.txt and a reward programme, no certification naming the API (5 of 20). Outputs carry a SynthID watermark, and uploads of minors and some recognisable people are refused in the EEA, Switzerland and the UK. 15 + 15 + 5 + 10 + 5 = 50.
- Vidu API (28): Model reading of the checklist (credential, training, retention, operator visibility, programme). One API key sent as `Authorization: Token`, no scopes found (20). The terms (effective 23 January 2025) let ShengShu examine, record, copy and use inputs and outputs for operational and other purposes, and don't rule out training (0). No retention period or deletion call found (0). Task list for per-task visibility, no audit log (8). No security.txt, bug bounty or certification found (0). Per the 1 October check, not re-read on 10 November (platform.vidu.com answered robots.txt with a redirect to its home page, so the host is left unread).

### Schema & documentation: Gemini Omni 1.2 Flash +21

- Gemini Omni 1.2 Flash (69): Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Called through the Interactions API, which the platform's Discovery document doesn't type; the SDK's generated Interactions types list the model (10 of 25). llms.txt with Markdown twins (10). The Omni guide, read on 11 November, covers Omni 1.1 Flash on the same API and lists what isn't supported (system instructions, temperature, negative prompts, audio references, YouTube sources) and the regional limits; it doesn't name 1.2 (16 of 20). Aspect ratio (16:9 or 9:16), resolution (360p, 720p, 1080p, 4k) and delivery are enumerated; length is set in the prompt, not a field (10 of 15). REST and SDK examples; a failed generation sets the file state to FAILED, and other error codes aren't documented beyond the platform's page (8 of 15). Dated SDK and platform changelogs (15). 10 + 10 + 16 + 10 + 8 + 15 = 69.
- Vidu API (48): No OpenAPI file (0). No llms.txt or Markdown copies, though the HTML reference pages render without a browser (0). The image-to-video reference says what each model family is for (Q3 for synced audio and storyboards, Q2 for speed and quality, Q1 for clarity) (15). Typed parameters with model lists, per-model duration ranges (1 to 16 seconds on Q3), resolution options and defaults, though one `model` field carries nine values whose valid durations differ (13). We found no error-code reference, and examples rest on the listing's check (5). A dated update log, latest entry 15 September 2026 (15). Per the 1 October check, not re-read on 10 November (platform.vidu.com answered robots.txt with a redirect to its home page, so the host is left unread).

### Reliability: Gemini Omni 1.2 Flash +10

- Gemini Omni 1.2 Flash (45): Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Status page at aistudio.google.com/status with no readable components or history (10 of 20) and no readable incident record (5 of 30). Platform rate-limit tiers; the public rate-limit page has no Omni 1.2 row (5 of 15). Backoff guidance for 429 and 503 and SDK retries (15). No SLA read for the Gemini API route, and the Omni guide says provisioned throughput isn't supported there; Google's post puts it on Google Cloud (0). Google's post of 5 November says generally available, and the SDK commit marks the model GA (10). 10 + 5 + 5 + 15 + 0 + 10 = 45.
- Vidu API (35): No status page found (0). No incident history to read (5). Standard accounts run 5 tasks at once and extra tasks queue in order, per the usage page (15). Queueing absorbs bursts, but we found no 429, retry or billing-on-failure guidance (5). No SLA (0). Q3 Pro and Q3 Turbo carry no preview label (10). Per the 1 October check, not re-read on 10 November (platform.vidu.com answered robots.txt with a redirect to its home page, so the host is left unread).

## Verdicts

**Gemini Omni 1.2 Flash.** Google's generally available video model makes clips of up to 15 seconds with audio, edits them turn by turn and upscales drafts to 1080p or 4K, from $0.023 a second at 360p to $0.209 at 4K. It is paid only, the guide still describes Omni 1.1, and every quality claim is Google's.

**Vidu API.** Q3 Turbo from $0.035 a second at 540p, about half that off-peak. No llms.txt, OpenAPI file or error-code reference.

## Before you call either

### Gemini Omni 1.2 Flash

1. Call POST /v1beta/interactions with model gemini-omni-1.2-flash and response_format type video; Veo is gone from the Gemini API
2. Set delivery to uri for clips over 4 MB and poll the file until ACTIVE; a later GET returns base64 only
3. Edit with previous_interaction_id and leave store on, or the clip can't be edited in a later turn
4. Set length in the prompt with timecodes such as [0-3s]; there is no duration field
5. Draft at 360p or 720p and upscale only the keepers: 4K costs about nine times 360p

### Vidu API

1. Send `Authorization: Token $VIDU_API_KEY`. The scheme is Token, not Bearer
2. POST the task, then poll the Get Creation endpoint by task id or set `callback_url`
3. Set `off_peak` only for jobs that can wait up to 48 hours. It roughly halves the credit rate
4. Set `audio` to true for dialogue and sound on Q3. It's off by default
5. Keep the AI-generated label on outputs. The terms forbid removing it
