# Superfast Video

Superfast Video is a proprietary, closed-weight text-to-video model developed
by **LINEARGAME PTE. LTD.** and made available under the **YorollAI** brand.
It generates 1344×768, 24 fps videos with audio through a hosted API.

> **API-only availability:** model weights, training code, inference code, and
downloadable checkpoints are not distributed through this repository.

## Try the model

- [Interactive Hugging Face Space](https://yorollai-superfast-video.hf.space/)
- [Yoroll Terms of Use](https://docs.yoroll.ai/yoroll-terms-of-use/en)
- Contact: [yoroll@support.ai](mailto:yoroll@support.ai)

The Hugging Face Space is a hosted evaluation interface. It sends requests to
the official Superfast API; inference does not run from model files stored in
this repository.

## Intended use

Superfast Video is intended for creative video generation, concept
visualization, prototyping, marketing creatives, social video, entertainment,
and other lawful uses permitted by the applicable service plan and the Yoroll
Terms of Use.

### Commercial use

- The public Hugging Face Space is provided for evaluation, demonstration,
  and non-commercial testing.
- General commercial use is available to eligible paid API customers, subject
  to the applicable service plan and the Yoroll Terms of Use.
- High-volume use, white-label or resale use, regulated or high-risk use cases,
  and uses requiring custom service levels or contractual assurances require a
  separate enterprise agreement.
- No access or license to the model weights, inference implementation, or
  other proprietary model technology is granted.

Subject to applicable law and the governing service terms, YorollAI does not
claim ownership of a user's eligible output solely because it was generated
using the service. Copyrightability varies by jurisdiction and by the degree
of human contribution. Outputs are not guaranteed to be unique, copyrightable,
or free of third-party rights.

## Restrictions and responsible use

Users must have all rights and permissions required for their prompts and
other inputs. The service must not be used for illegal content, fraud,
deceptive impersonation, privacy or publicity-rights violations, infringement
of intellectual property, sexual exploitation, or other uses prohibited by
the Yoroll Terms of Use or applicable law.

Users are responsible for reviewing generated content before publication or
commercial deployment. Extra review and safeguards are necessary when content
depicts real people, brands, protected characters, sensitive events, or other
third-party rights.

## Limitations

- Generated video may contain visual, temporal, physical, textual, or audio
  inconsistencies.
- The service does not guarantee factual accuracy, identity consistency,
  uniqueness, fitness for a particular purpose, or non-infringement.
- Generation is asynchronous and may include queueing time.
- Result links returned by the current hosted preview are temporary.
- Capabilities, limits, and output characteristics may change as the hosted
  service is updated.

## Model and training information

The architecture, parameter count, model weights, training code, detailed
training data composition, and production inference implementation are
proprietary and are not published in this repository. Evaluation results will
be added when a public, reproducible evaluation methodology is available.

## License and terms

Superfast Video is closed-weight and proprietary. This repository is an
informational model card and does not distribute or license model artifacts.
Access to the hosted service and use of generated outputs are governed by the
[Yoroll Terms of Use](https://docs.yoroll.ai/yoroll-terms-of-use/en), the
applicable service plan, and any separately executed agreement.
