Lightricks releases LTX-2.5, a 22B open-weights audio-video 'world model' with multishot generation and up to 4K output
On Aug 11, 2026 Lightricks released LTX-2.5, a 22B-parameter open-weights model that generates synchronized video and audio from text, images or video, keeps characters and voices consistent across cuts (multishot), and ships a checkpoint for robotics and physical AI. Free for organisations under $10M revenue, it became the most-downloaded generative model on Hugging Face (~1.6M downloads a month by October).
Key facts
- 22B DiT in a full (trainable) and a distilled 8-step variant; Gemma 4 12B text encoder; new diffusion video decoder (Hugging Face model card)
- Speed: a 10-second 720p image-to-video clip in 6.8 s on two Nvidia GB200 superchips (Lightricks via VentureBeat)
- Up to 4K (3840×2176); clips up to 20 s at 24/25 fps through the API; native audio with an integrated vocoder
- LTX-2.x Community License: free for commercial use under $10M annual revenue, paid licence above; use for military/weapons development is banned
- Managed API: Fast tier $0.09/s, 4K $0.30/s (VentureBeat)
- Lightricks cites 33M+ cumulative downloads for the LTX family; LTX-2.5 had ~1.58M monthly downloads and topped Hugging Face weekly trending on Oct 1, 2026
- CEO Zeev Farbman: 'With video models, world models, there are so many different use cases that require people to get access to the weights'
What happened
Lightricks, the Israeli maker of Facetune and LTX Studio, released its third major open video model generation. LTX-2.5 runs locally, has day-one ComfyUI support, and is pitched both for creative video and as a world model for real-time applications and robotics.
Why it matters
Most frontier video models (Veo, Sora, Kling) are closed. LTX-2.5 is among the strongest open audio-video models anyone can fine-tune, and its download numbers make it a default base for the open video community.
