LTX-2 Audiovisual Model

LTX-2 is an open-source audiovisual foundation model that generates high-quality, temporally synchronized video and audio content from text prompts. It features an asymmetric dual-stream transformer architecture (14B video + 5B audio parameters) with bidirectional cross-attention, achieving state-of-the-art quality among open-source systems while being 18× faster than comparable models and supporting up to 20 seconds of continuous generation.
