What it does
LTX-2 is an AI model from Lightricks that creates video together with synchronised audio, from a text description or a starting image.
It offers different modes that trade speed for quality, and it can produce high-resolution results. The code and model files are published openly to download and run.
Running it means downloading large model files and using a powerful graphics card.
Who it's for
Developers and researchers who want to generate video with sound on their own powerful hardware.
Can I use it without coding?
