LTX-2.5: All models can be downloaded here: https://huggingface.co/Lightricks/LTX-2.5
LTX-2-5 is already "split files" from the official source, and they work out of the box with most of the older workflows (just swap out the models). You can find the 2.3 workflows here: https://huggingface.co/RuneXX/LTX-2.3-Workflows (most all of them should work fine with LTX.2.5 models)

LTX-2.5 also works with most LTX-2.3 loras and is quite backwards compatible. Dedicated LTX-2.5 workflows are coming asap ;-) (but feel free to use LTX-2.3 workflows with the LTX-2.5 models. Most all should work)
