LTX-2.3 Video Model Manager

Hey guys… LTX-2.3 just dropped, and honestly it’s kind of wild. As great as the last model was, it was hard to imagine a big jump in quality… but they did it again. Sharper visuals, smoother motion, stronger prompt understanding, and noticeably cleaner audio. Lightricks keeps pushing this model forward.

I’ve already put together a Get Going Fast installer so you can run LTX-2.3 locally in ComfyUI without fighting through setup.

Highlights

• Better detail and textures
• Improved image → video animation
• Cleaner audio generation
• Much stronger 9:16 portrait video support
• Improved text rendering in video 🚀

How to Install

1. Update your ComfyUI installation
2. Extract the zip file just outside your ComfyUI folder
3. Double click the installer
4. Choose fp8 or the full dev version (speed vs size & quality)

Inside the installer I’ve included the workflows and models you need to get started, so you can jump straight into Text → Video or Image → Video generation right away.

For this Day-0 release, the installer includes both Text → Video and Image → Video workflows. I’ll be updating the installer regularly as new workflows drop, including GGUF versions and ControlNet support as those become available.

In the meantime, enjoy the Day-0 release and let’s see what kind of things you start creating! 🚀
