Evidence claims:
- [upstream_claim] README says LTX-2 is now the primary home for LTX development; lists releases v0.9.0 (Nov 2024) to v0.9.8 (Jul 2025) with distilled, FP8 and 2B/13B variants; capabilities include I2V, multi-keyframe conditioning, forward/backward extension, V2V, depth/pose/canny control. · source: https://github.com/Lightricks/LTX-Video
- [upstream_claim] HF model card lists most versions under the 'LTX-Video Open Weights License 0.X' with separate license files for 0.9, 0.9.1 and 0.9.5; recommends resolution divisible by 32, 8n+1 frames, under 257 frames. · source: https://huggingface.co/Lightricks/LTX-Video
- [sourced_fact] License text: free use/modification/distribution subject to use restrictions; entities with >= $10M annual revenue need a Commercial Use Agreement; derivatives expressly include models trained on outputs via distillation or synthetic data. · source: https://huggingface.co/Lightricks/LTX-Video/blob/main/LTX-Video-Open-Weights-License-0.X.txt
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

Rights:
- code: license=Apache-2.0 hosting=permitted redistribution=permitted modification=permitted training=unknown · README states code is Apache-2.0. · evidence: https://github.com/Lightricks/LTX-Video
- model_weights: license=LTX-Video Open Weights License 0.X hosting=restricted redistribution=restricted modification=permitted training=restricted · License 0.X read: Attachment A use restrictions flow down; $10M+ revenue entities need separate commercial agreement; hosting for third parties allowed with conditions; derivative definition covers distillation and synthetic-data training from outputs; licensor may remotely restrict/update (Section 6). Early 2B versions have their own license files (not read) and v0.9.5 reportedly uses OpenRAIL-M per README. · evidence: https://huggingface.co/Lightricks/LTX-Video/blob/main/LTX-Video-Open-Weights-License-0.X.txt
