LTX Video

LTX Video here means Lightricks' first-generation open video model, the one whose weights and inference code live in the Lightricks/LTX-Video repository. The vendor now calls it LTXV and presents it as the opening generation of a family that continues through LTX-2, LTX-2.3 and LTX-2.5, so the name on this entry is a generation marker rather than the current model. On the vendor's own model page LTXV is described as the foundation of the line: fast inference with strong temporal consistency for text-to-video and image-to-video, motion and depth control, LoRA and IC-LoRA support, built to run on high-end and consumer GPUs alike, and video-only with no integrated audio. The newer generations are the ones carrying native audio, portrait output and multi-shot consistency.

It suits people who want a video model running on their own hardware, whose own fine-tunes or ComfyUI workflows matter more than a leaderboard, and who are content to move with the releases. It suits less well anyone who needs synced audio, the strongest prompt adherence or the current quality ceiling, because those belong to the later models in the family, and it suits less well a team that will not track releases: the repository's last push was 2026-01-05, months before this writing, while the vendor's line has continued past it. Treat the local install as a starting point that will need replacing rather than a fixed asset.

Not verified: no model was run and no video was generated here, so the speed and fidelity claims are the vendor's and the project's, not results reproduced for this entry. The repository's code is Apache-2.0, but the weights on Hugging Face are marked License: other and link a separate LTX-Video Open Weights License, so the code and the weights are not under one licence; as read through the GitHub API on 2026-10-12, 11,074 stars for a project created 2024-11-20 with its most recent push on 2026-01-05; how much the current code differs from the release this entry describes was not read. The vendor's model page describes a licensing split for the newest generation with a revenue threshold below which it is free and a commercial licence above it, but the terms themselves were not read in full here and no figures are quoted. The site's older /ltxv path returned a 403 to this fetch, so the content above comes from the current model page and the GitHub API; whether LTXV is still maintained at all, and whether it is still offered in the vendor's studio product, were not confirmed.
