Israeli tech company Lightricks has launched LTX Video (LTXV), a new open-source AI model that generates five-second videos in just four seconds. As Michael Nuñez reports for VentureBeat, the company aims to challenge major tech firms by making its technology freely available. The model runs efficiently on consumer-grade hardware like Nvidia RTX 4090 GPUs while maintaining high visual quality. LTXV features two billion parameters and will be released on GitHub and Hugging Face under an OpenRAIL license. CEO Zeev Farbman explains that making the model open source will foster innovation and adoption, particularly in academia and among developers. The company, known for its Facetune photo-editing app, sees this move as essential for competing with tech giants like OpenAI, Adobe, and Google.
