If you are coming here and downloading for the first time it's already available.
LTX 2.3 just dropped and figured it was a good time to update a bit.
Models all updated for LTX 2.3, basically the same workflow as LTX 2
We are still using the old LTX2 distill lora as it is working just fine for now. The lora is HUGE at 7+gb total. Previously someone released a lower rank more manageable one which we use right now. Staying with this one for now until I can find a lower rank or make one myself.

Removed the audio nodes as those were creating a lot of problems and hopefully LTX has fixed the audio which to me it seems much better.
Removed the tvae previews, no longer working as 2.3 has a new VAE anyway. You just get blurred static but video comes out fine.
LTX claims to have fixed the portrait video so those should work now. Create those tikkie tokkies to your hearts content
https://huggingface.co/Lightricks/LTX-2.3 if you're looking for more info on the updates.
No examples yet but I'll drop a vid when I get the chance.
With this right now I'm only uploading the all in one zip which will contain the t2v, i2v, ta2v, ia2v, v2v as usual. I WANT ALL THE THINGS! will be the only one available for now.
I'm doing some testing to see if these settings are going to stay the same, change, if we still need lower strength on distill lora etc. I'll update all workflows as needed. For now all tested and working by me.
