LTX-2.x-Community-License(LTX-2.5: commercial use free for entities under USD 10M annual revenue, a paid license above it, with use-based restrictions

LTX-2 and 2.3 carry the LTX-2 Community License on the same terms)+LTXV-Open-Weights-License-0.X(LTX-Video 0.9.6 to 0.9.8, with the same USD 10M threshold)+Open-RAIL-M(LTX-Video 0.9.1 and 0.9.5

use-based restrictions only)

LTX is free for commercial use by organizations under USD 10M in annual revenue, with a paid license above that. Lightricks publishes a fine-tuning trainer but not the pretraining code or data. LTX-2.x-Community-License and LTXV-Open-Weights-License-0.X allows commercial use only within a bound, so the license tier is use_bounded.
