Open models
for open worlds

Training robots means teaching them how the physical world actually behaves, not just what it looks like. LTX-2.5 is the open model that gets closest to that for us, and being able to run and fine-tune it on our own hardware is what makes it usable for real robotics work. We have not found another open model that does this for us the way this one does.

The future of media is real-time, and it only works if the underlying model is fast, controllable, and yours to run. Partnering with LTX means we can tune the model to our own infrastructure and bring live, responsive avatars to users worldwide.

ComfyUI and LTX share a simple belief, that open models build better tools, faster. With LTX-2.5 running natively in ComfyUI, a developer can go from an idea to a working world-model pipeline in an afternoon, and an enterprise can take that same pipeline straight into production on its own hardware. Open is what lets the community move fast and lets businesses build on what it proves.

We love building on top of LTX because it's one of the most capable models out there, and there's no other model we can personalize like this today. We already have over 80 fine-tunes of LTX on our platform, and that number grows every day. It's not a black box, it's something we can control, like a tool.

Features like the ACES workflow are what excite us about LTX and its models. The LTX team is building genuine production workflows that integrate naturally into the hybrid environments we're creating at Asteria. LTX listens to filmmakers and delivers tools that work in real production. We can't wait to start using LTX 2.5.
