LTX Video (Lightricks)
Open-source AI video generation
By Lightricks
Our verdict
LTX Video is the only fully open-source option in the market, which makes it interesting for specific use cases. We have tested it for internal R&D and spec work exploration where volume matters and quality is secondary. The real-time generation speed is impressive. For production client work, the 768p resolution and quality gap versus Kling or Runway make it unsuitable as a primary tool. It is most valuable as part of a multi-tool pipeline where speed and cost matter for initial exploration, with hero assets produced in higher-quality tools.
