EU AI Act

Article 50(2) of the EU AI Act requires AI-generated content to be marked in a machine-readable way. Video and audio generated by the LTX API carry an invisible watermark that identifies them as AI-generated. For our other EU AI Act disclosures, see the LTX Transparency Hub.

Invisible watermark

A watermark is a pattern hidden in the content itself. Ours sits in the pixels of every frame and in the audio samples, and is designed to be invisible and inaudible.

A watermark isn’t a cryptographic signature. It suggests that a file came from LTX, but it can’t prove who made the file or that nobody changed it.

We use two open watermarking models from Meta:

Detecting the watermark

The detector is open source and runs in Python, on your own machine.

  1. Install the detector by following the LTX-2 marking guide.
  2. Download the detector weights from Hugging Face to a local folder.
  3. Run the detector on your file, as shown in the marking guide.

A negative result doesn’t prove a file isn’t AI-generated: it may have been made with another tool, or the watermark may have been removed.

FAQ

Yes. The detector is open source.

No. Detection runs on CPU. A GPU is faster.
