Tech company Lightricks has released LTX Video (LTXV), the first real-time AI video generation open-source model. Capable of generating stunning, high-quality videos faster than real-time playback, LTX Video can produce five seconds of 24fps video at a resolution of 768x512 pixels in just four seconds on an Nvidia H100 GPU. The 2-billion-parameter DiT-based model supports both text-to-video and image-to-video functionalities and is designed to run efficiently on consumer hardware, including GPUs like the RTX 4090. Lightricks has open-sourced the code and model weights on GitHub, encouraging community-driven development. The model is integrated with platforms such as ComfyUI, Hugging Face, and FAL, making it accessible for users to run locally. The release aims to democratize AI video creation by providing an open-source alternative to existing proprietary models.
