Lightning-Fast Generation
LTX 2 Fast delivers video results in seconds, not minutes. The optimized inference pipeline enables real-time creative iteration, allowing you to visualize concepts instantly without waiting for lengthy render times. As the fast mode of the 19-billion parameter LTX-2 model, it strikes the perfect balance between speed and quality, making it ideal for rapid concepting and pre-visualization workflows.
Unified Audiovisual Generation
Experience the groundbreaking advantage of LTX 2 Fast's DiT-based architecture. As the first model to natively generate synchronized audio and video in a single pass, it eliminates the need for separate audio workflows. Characters speak with perfect lip-sync, footsteps align precisely with movement, and environmental sounds emerge naturally from visual elements. This holistic approach from Lightricks revolutionizes content creation.
Professional Control & Flexibility
LTX 2 Fast provides sophisticated creative control through advanced prompt interpretation and camera movement capabilities. The 19B parameter foundation enables nuanced understanding of cinematic terminology, from complex camera moves to subtle lighting changes. Multi-keyframe conditioning allows precise temporal control over scene evolution, while the fast iteration mode lets you explore multiple creative directions rapidly before committing to final renders.
Open-Source Innovation
LTX 2 Fast is released under the Apache 2.0 license, representing Lightricks' commitment to democratizing advanced AI video technology. The open-source approach enables researchers, developers, and creators worldwide to build upon this foundation, customize workflows, and contribute to the evolution of audiovisual AI. Whether you're developing custom applications or integrating into existing pipelines, LTX 2 Fast offers unparalleled accessibility and flexibility.
