LTX releases LTX-2.5, an AI video model generating clips in 6.8 seconds

LTX, the generative media company spun out of Lightricks, released LTX-2.5, an open-weights AI video model that generates clips in 6.8 seconds, with native ComfyUI integration and a free tier for organizations with under $10 million in annual recurring revenue. The model is available as open weights on Hugging Face, in ComfyUI, and via the LTX API, and the company claims its model family has surpassed 33 million downloads.

Via maxvideoai.com LTX releases LTX-2.5, an AI video model generating clips in 6.8 seconds The open-weights model from Lightricks spinout launches with native ComfyUI integration and a free tier for smaller companies 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. LTX says its model family has now surpassed 33 million downloads, which the company claims makes it the most-used open “world” model line on the market. The road from Lightricks to open-weights video LTX’s lineage traces back to Lightricks, the company behind consumer photo and video editing apps like Facetune. The spinout first released a text-to-video model in 2024, establishing itself as an early mover in the open-source video generation space. The model has evolved steadily since then. LTX-2 landed in October 2025, followed by an interim version, LTX-2.3, in March 2026. Each release has layered on new capabilities, including synchronized high-resolution audio-video output and improvements to local-run efficiency, meaning users can generate video on their own hardware without shipping data to a cloud endpoint. The 6.8-second generation time positions LTX-2.5 as one of the fastest options in a field where competing models can take significantly longer to produce comparable output.
