4K video AI 2
First open-source 4K AI model for synchronized video and audio generation.
LTX-2 is a state-of-the-art, production-ready AI foundation model developed by Lightricks for generating synchronized audiovisual content. It is the first fully open-source, open-weights AI model that supports native 4K resolution (2160p) video generation at up to 50 FPS, along with synchronized audio generation (including dialogue, ambient sounds, and music). Powered by a 19B parameter Diffusion Transformer (DiT) architecture, LTX-2 supports text-to-video and image-to-video generation, creating clips up to 20 seconds long. It is optimized for NVIDIA GPUs, offering 3x faster performance on RTX 50 Series.
