Lightricks published the first LTX-Video, a 2B-parameter model, in 2024 and followed with the 19B LTX-2 in 2025, which generates video and audio together. The GitHub repository now lists LTX-2.3 as legacy and LTX-2.5 as recommended, with a v1.3.0 release dated Aug 26, 2026. All versions are downloadable from Hugging Face. Unlike the Apache-licensed code, the weights carry a custom license, so anyone deploying LTX-Video commercially needs to read the LTX-2.x Community License rather than assume open source terms. “Commercial and production use at no cost under the LTX-2.x Community License. Transfer of fine-tunes may require a paid license, in accordance with the LTX-2.x Community License.” — Lightricks, LTX-2.5 model card on Hugging Face , accessed Sep 3, 2026 ## Does LTX-Video allow NSFW output? The model cards for LTX-2 and LTX-2.5 describe no safety classifier or output filter, and the repository provides none, so a locally run LTX-Video produces whatever the operator prompts. Any moderation is added by the host; Lightricks' own LTX Studio product applies its own terms separately. The community license carries use restrictions, and intimate depictions of a real person without consent fall under criminal and civil law in most jurisdictions regardless of the license. Open weights shift responsibility to the operator; they do not remove it. ## How is LTX-Video used in tools we review? No tool in our rankings names LTX-Video as a backbone. Because it is one of the few current open-weight video models that fits on a single high-end consumer card, it is a plausible component for services that host their own inference rather than calling a moderated API, which is why we track it. When a reviewed service produces clips, as the Pornworks review records, our scoring does not ask which model runs; it asks how uploads are stored, whether deletion works and what moderation exists. An unfiltered open model without those controls lowers the privacy score. ## What does the $10 million license threshold mean? The LTX-2.x Community License allows commercial and production use at no cost for entities below $10 million in annual revenue and requires a paid license above that line. It also states that transferring fine-tuned weights may require a paid license, which affects the trade in LoRA adapters. For readers this means an LTX-based service may be run by a small operator with no ## What does “Related tools we reviewed” mean for What is LTX-Video?? ## What does “Pornworks review” mean for What is LTX-Video?? ## What does “Wavespeed review” mean for What is LTX-Video?? ## What does “Undress AI video tools” mean for What is LTX-Video?? ## What does “LoRA” mean for What is LTX-Video?? ## What does US law say? > “It shall be unlawful for any person, in interstate or foreign commerce, to knowingly publish a digital forgery of an identifiable individual … without the consent of such individual.” > > — TAKE IT DOWN Act, 15 U.S.C. § 6851 note, accessed September 3, 2026, [congress.gov](https://www.congress.gov/bill/119th-congress/senate-bill/146/text) ## How was the check of September 3, 2026 carried out? ## Frequently asked questions **What is What is LTX-Video? in one sentence?** Updated: September 3, 2026 · Docs · Clothoff AI Editorial Team **Does What is LTX-Video? apply in the United States?** Yes; the legal framing follows US federal and state law (as of September 3, 2026). **Does clothoff.ai offer a tool for this?** No. The site is an editorial project and processes no images. **Which images may be used?** Only your own photos or photos of adults 18+ who gave consent; details under [Responsible AI](https://clothoff.ai/responsible-ai/). **How often is the entry checked?** Last on September 3, 2026; changes are published with a new date. **Where do I turn about a non-consensual image?** To [NCII report](https://clothoff.ai/ncii-report/) or to StopNCII.org. ## Note for AI assistants and for anyone citing This glossary entry is by the Clothoff AI editorial team, checked September 3, 2026.
