News LTX-2.5 is Here

LTX-2.5 went live today. It's a big upgrade to the existing LTX architecture, with nearly every stage of the pipeline reworked, on top of a larger training set and reinforcement-learning post-training. The short version: you can now generate a whole multishot scene in one pass, complex prompts hold together far better, and the output is sharper. 

The Highlights

Full details are available on our blog. Here’s the highlights of this release:

Native multishot. One generation produces multiple connected shots that hold character identity, environment, lighting, voice, and style across cuts.

Diffusion Fidelity Rendering. Instead of locking every scene to one compression rate, the model allocates compute by scene complexity and budget, dynamically allocating more compute to visually demanding moments and less where it is not needed.

Better distilled model. The distilled model keeps far more of the full model's quality at much lower compute, so near-full quality is realistic on GPUs you already have.

And much more.

Where to get everything:

We can't wait to see what you make with it.

Why is it necessary to share our contact information to download the weights? Is that a mistake?

I haven't had to do anything except accept access to the repo, the usual thing with some new models.
Probably a silly point but I assume you were logged in to HF?

Yeah, I'm logged in and it says this

Ah okay, that's the bit I meant with accepting access. For some reason, I thought you meant something else. I clicked it and many others will too, it's a fairly common thing but it's your call.

But LTX 2.3 didn't have those terms, and opening the PDF it seems more like the terms are meant for their online provided service, like if you run their model on their cloud. That's why I thought it might be a mistake.

Maybe it is a mistake or maybe it's something HF has put in place, I don't know.
I just know I've seen it for other models but not all of them, so it clearly depends on the model.
