LTX Model

LTX Model is an open-source foundation model designed for generating synchronized video and audio content at production quality. Built on a 22-billion-parameter asymmetric dual-stream diffusion transformer, it supports text-to-video, image-to-video, and audio-to-video generation with cinema-grade output, character continuity across shots, and editable formats like EXR. The project describes itself as built for real production workflows rather than research isolation.

Available as open weights (free for companies under $10M revenue), via API with predictable pricing, or deployed on-premises. LTX Desktop, an open-source companion application, enables local generation on supported NVIDIA GPUs and Apple Silicon Macs, with API fallback for unsupported hardware. The model supports fine-tuning through LoRA and includes video editing capabilities.
