What is LTX-Video?
Lightricks' open-weight video line, from the 2B LTX-Video of 2024 to the 19B LTX-2.5 of 2026 — no cost under $10M revenue, no built-in filter.
LTX-Video is an open-weight video generation model line developed by Lightricks, the company behind Facetune, with the first 2B-parameter model released in 2024, the 19B LTX-2 in 2025 and LTX-2.5 in 2026. Code is Apache 2.0 and weights ship under the LTX-2.x Community License, which permits production use at no cost for organizations below $10 million in annual revenue.
| Version | Date | Developer | License / Access | Filters |
|---|---|---|---|---|
| LTX-Video (LTXV, 2B) | 2024 (day not restated on the current repository) | Lightricks | Open weights; custom Lightricks license | No safety filter stated in the model card |
| LTX-2 (19B) | 2025 | Lightricks | Code Apache 2.0; weights under the LTX-2.x Community License | No built-in filter stated |
| LTX-2.3 | 2026 (listed as legacy on the repository) | Lightricks | Same license | No built-in filter stated |
| LTX-2.5 | 2026 (repository release v1.3.0 dated Aug 26, 2026) | Lightricks | LTX-2.x Community License: no cost under $10M revenue, paid above; fine-tune transfer may need a paid license | No built-in filter stated |
Lightricks marks LTX-2.5 as the recommended model and lists LTX-2.3 as legacy; the current repository does not restate the original 2024 release day.
Which LTX-Video versions exist?
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.”

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 contract with Lightricks at all. The LoRA and image-to-video entries cover how adapters and input frames shape what such a service can produce.

Frequently asked questions about LTX-Video
Is LTX-Video open source?
The inference code is Apache 2.0, but the weights are not open source in the OSI sense. LTX-2 and LTX-2.5 ship under the LTX-2.x Community License, which allows commercial use at no cost below $10 million in annual revenue, requires a paid license above it and may require one for transferring fine-tunes.
When was LTX-2.5 released?
The Lightricks repository lists LTX-2.5 as the recommended model with a v1.3.0 release dated Aug 26, 2026, and the Hugging Face model card was current on Sep 3, 2026. The exact first-publication day of LTX-2.5 is not restated on those pages, so the table records the year and the release tag we could verify.
Does LTX-Video include a safety filter?
No. The model cards and repository describe no NSFW classifier or output filter, so filtering is entirely the operator's choice. Lightricks' hosted LTX Studio applies its own product terms, but a locally run copy of the weights produces whatever it is prompted to produce.
What hardware does LTX-2.5 need?
LTX-2.5 is a 19B-parameter model that Lightricks distributes with quantized variants for consumer graphics cards, alongside full-precision weights for data-center hardware. Memory needs depend on resolution, clip length and whether audio is generated; the repository documents the supported configurations and example commands.
Can LTX-Video animate a photo of a real person?
Image-to-video is a supported mode, so technically yes. Legally, turning an identifiable person's photo into intimate video without documented consent is unlawful in the United States, the EU and elsewhere, and the community license's use restrictions apply on top of that, whatever the hosting choice.
Do the tools we review run on LTX-Video?
No reviewed tool names LTX-Video publicly. Because the model is small enough to self-host, we treat it as a plausible backbone for services that avoid moderated APIs, but our scores rest on tested behavior: upload handling, retention, deletion and moderation, not on which weights a vendor loads.
