+1.6. “Licensor” means the owner that is granting the license under this Agreement. For the purposes of this Agreement, the Licensor is Lightricks Ltd.
+1.7. “Model” means any accompanying machine-learning based assemblies (including checkpoints), consisting of learnt weights, parameters (including optimizer states), corresponding to the Lightricks’ Model “LTX Video-2B-04-25” model architecture as embodied in the Complementary Material, that have been trained or tuned, in whole or in part on the Data, using the Complementary Material. 
+1.8. “Output” means the results of operating a Model as embodied in informational content resulting therefrom.

Any commercial use of the Model or Derivatives of the Model by the Commercial Entities not in accordance with this Agreement and/or the Commercial Use Agreement is strictly prohibited and shall be deemed a material breach of this Agreement.

Such amount reflects a reasonable estimation of the losses and administrative costs incurred due to such breach. You agree and understand that this remedy does not limit the Licensor's right to pursue other remedies available at law or equity.
