LTX, the generative media company that spun out of Israeli app maker Lightricks, has dropped LTX-2.5, the latest iteration of its open-weights video and “world” model. The headline number: it can generate video clips in 6.8 seconds, a speed that puts it in rarefied air among open-source video generation tools.
The model arrives with native integration into ComfyUI, the node-based workflow environment that has quietly become the standard prototyping tool for anyone serious about open generative media.
What LTX-2.5 actually delivers
The model is available immediately in three forms: as open weights on Hugging Face, inside ComfyUI through a day-one launch partnership, and via the LTX API for teams that prefer managed infrastructure.
The licensing structure is designed to be startup-friendly. Organizations pulling in less than $10 million in annual recurring revenue can use the model for free. Companies above that threshold need to negotiate a commercial license.
