# Gemini Omni Flash 1.1

Non-explicit game trailers revised through conversation

- **Availability**: available
- **Where it runs**: hosted
- **Costs**: Paid-tier Gemini API billing meters input and output tokens. Check current rates for your planned duration and resolution before budgeting revisions.
- **Adult content policy**: restricted

Gemini Omni Flash 1.1 is worth considering for a game trailer that needs several rounds of changes. Bring character art and short video references, then use follow-up prompts to revise lighting, framing or individual elements. It can generate sound alongside the picture, though the current API does not accept uploaded audio references or support voice editing. Those limits matter if your trailer depends on an existing performance. Keep original art, dialogue and edit notes locally so you can track revisions. Check character continuity and generated sound before publishing, including any rights issues, and compare upscaled delivery options with the native output.

## Commercial use & license

Proprietary hosted model. Google's service terms govern access and use; no downloadable weight license is established for this model.

## Adult content rules

Google prohibits sexually explicit content created for pornography or sexual gratification. Limit work here to permitted non-explicit assets.

[Read the policy](https://policies.google.com/terms/generative-ai/use-policy?hl=en)

## What you need

Paid-tier Gemini API access and an API key; use gemini-omni-1.1-flash through the Interactions API. Keep interaction storage enabled for follow-up edits. Default output is 720p; uploaded videos for editing or extension are limited to 10 seconds.

Ranks are recommendations for the task described, based on reviewed documentation. Model ranks cover non-explicit development work. We have not run practical benchmarks. Check content policies and commercial terms separately. [How the ranks work](https://bestadultgames.io/en/developers/methodology.md)

## Why consider it

- Combine character art and short video references
- Revise scene elements through follow-up prompts
- Generate picture and sound from the same brief

## Tradeoffs to plan for

- Uploaded-video edits are unavailable in the EEA, Switzerland and UK; audio references and voice editing are unsupported
- 1080p and 4K delivery use upscaling; inspect detail against the native output
- Google's content policy excludes pornography and content intended for sexual gratification

The tier reflects documented fit for the workflow described here and availability. No numeric score or hands-on performance results are provided.
