LTX-Video
Lightricks · Video · 2B · Released 21 November 2024
LTX-Video stands out for speed: it is a diffusion transformer built to generate video quickly, with a distilled variant the makers describe as near real-time on an H100. The 2B model is the light-VRAM option and runs best under 720x1280 and fewer than 257 frames. It is used mainly through ComfyUI or Hugging Face diffusers. The licensing is the wrinkle: the code is Apache 2.0, but the weights ship under a custom, version-specific open-weights licence, so anyone planning commercial use should read the licence file for the exact checkpoint they download rather than assume.
Strengths
- Fast, with a distilled variant approaching real-time on strong hardware
- The 2B variant targets modest VRAM, unusual for open video
- Well integrated into ComfyUI
Weaknesses
- The weights licence is custom and version-specific, so commercial terms need checking
- Official VRAM figures are not published; community reports vary
- Works best within specific resolution and frame-count limits
Hardware requirements

LTX-Video: common questions
- What hardware do I need to run LTX-Video?
- At its most compressed (Native (2B)) it needs roughly 12GB of VRAM, and about 12GB for good quality. VRAM figures are approximate and depend on context length and settings.
- Is LTX-Video free for commercial use?
- Commercial use is permitted, but with conditions. The code is Apache 2.0, but the model weights ship under a custom, version-specific LTX-Video Open Weights License, and the terms differ per checkpoint. Read the licence before relying on it at scale.
- Can I run LTX-Video on Apple Silicon?
- It can run on Apple Silicon through general runtimes, but it is not specifically optimised for it.
