Third-party processing
Prompts and uploaded media go directly to the embedded Hugging Face Space and its maintainer. Do not upload private, confidential or unlicensed material.

The exact controls live inside the embedded Space and may change as its maintainer updates the demo.
Add the requested source media or prompt.
Choose quality, duration or transformation controls inside the Space.
Join the ZeroGPU queue, then preview or download the result.
Free, with shared GPU limits
Hugging Face makes existing ZeroGPU Spaces free to use, but access is quota-based and queue priority varies by account tier.
Large jobs can use most or all of a daily quota. A public demo is not a production SLA.
Can this Space be used as an API?
Public Gradio Spaces expose API endpoints, but schemas, availability and rate limits can change. Inspect the current API definition before integrating it.
Use the Space API for experiments, not as an assumed permanent or unlimited backend.Client("Lightricks/LTX-2-3-hdr")

Frequently asked questions
Is this LTX tool free?+
The embedded public Space can be used within Hugging Face ZeroGPU quota and queue limits. It is not unlimited compute.
Do I need an LTX API key?+
No LTX API key is required for the embedded public demo. Hugging Face may ask you to sign in for more quota.
Does Wan2.Video process my files?+
No. The iframe sends inputs to Hugging Face and the Space maintainer; Wan2.Video only hosts this guide.
Can I use the output commercially?+
Check the model license, source-media rights and the Space terms for your exact workflow before commercial use.
