LTX-2

LTX-2 is the DiT-based, open-source AI foundation model for production-grade video, delivering native 4K resolution at 50 FPS with perfectly synchronized audio.

This is LTX-2: Lightricks' next-generation audio-video foundation model engineered for professional workflows. It's built on a DiT architecture and is the first model to generate video and audio in one coherent, synchronized process. The tech supports native 4K resolution and up to 50 FPS performance, allowing for high-fidelity, continuous clips up to 20 seconds long. We've optimized it for efficiency (up to 50% lower compute cost) and creative control, offering features like multi-keyframe conditioning, IC-LoRA control models, and full open-source weights for maximum customization.
