LTX-Video's open weights carry a revenue-based license line

The shot

Lightricks Ltd., an Israeli creative-software company, maintains LTX-Video as an openly published model whose weights and code sit in a public repository distinct from the company's separate LTX Studio shot-to-scene pipeline product. The company's own technical report, posted to arXiv on 30 December 2024 as "LTX-Video: Realtime Video Latent Diffusion," describes a transformer-based latent diffusion model built around a highly compressed Video-VAE, and states it produced five seconds of 24-frame-per-second video at 768-by-512 resolution in two seconds on an Nvidia H100 GPU. As retrieved on 16 September 2026, the repository documents a version history running from an initial 2B model through 13B "dev" and "distilled" checkpoints.

What the documents show

The paper's "faster-than-real-time" and best-in-class claims are Lightricks's own reported benchmark. The decisive fact for anyone weighing production use sits elsewhere, in the model license rather than the paper: the current LTXV Open Weights License, dated 15 April 2025, grants a royalty-free license "for any purpose" subject to listed restrictions, but adds that "entities with annual revenues of at least $10,000,000... are eligible to obtain a paid commercial use license, subject to the terms and provisions of a different license," and states that commercial use by such entities outside that separate agreement "is strictly prohibited." The repository's own release notes show this license superseded an earlier OpenRAIL-M license introduced in March 2025, which itself replaced still-earlier per-version license files: a live document whose governing terms have changed more than once.

The workflow

Downloading LTX-Video's weights from Hugging Face does not by itself clear a production for commercial use if that production's parent company meets the license's revenue threshold; the license requires that company to separately contact Lightricks for a Commercial Use Agreement. Below that threshold, the grant covers use "for any purpose" so long as it avoids the license's Attachment A restrictions, which bar uses including undisclosed impersonation and generating content intended to harm others. The human decision a studio or vendor still has to make is checking its own revenue against the stated figure and reading Attachment A before relying on generated output in a release.

What the tool does not change

A stated real-time generation benchmark describes inference speed on specific hardware in Lightricks's own test, not a guaranteed on-set turnaround. It is also worth separating LTX-Video, the open-weights model this record covers, from LTX-2, a newer foundation model the same company announced in October 2025 whose weights the same repository states will be released to the community later, on a separate timeline and, presumably, under its own license terms.

• Does the entity relying on LTX-Video's output meet the license's stated $10 million annual revenue threshold?
• Which of Attachment A's use-based restrictions could apply to the specific production use being planned?
• Which version of the LTX-Video license governs the specific checkpoint in use, given that the terms have changed across releases?

LTX-Video's weights are open to inspect and run, but the license that governs commercial use is a separate, changeable document, and only that document, read as currently retrieved, settles what a given production may do with it.
