22 Agreement.
23
24 "Derivatives of LTX-2" means all modifications to LTX-2, works
25 based on LTX-2, or any other model which is created or initialized
26 by transfer of patterns of the weights, parameters, activations or
27 output of LTX-2, to the other model, in order to cause the other
28 model to perform similarly to LTX-2, including – but not limited
29 to - distillation methods entailing the use of intermediate data
30 representations or methods based on the generation of synthetic
31 data by LTX-2 for training the other model. For clarity, Derivatives
32 of LTX-2 include: (i) any fine-tuned or adapted weights, parameters,

38 claim exclusive ownership rights in any Derivatives of LTX-2 that
39 would restrict the rights granted herein.
40 "Entity" means any individual, corporation, partnership, limited

60 distributed and made publicly available by Lightricks (including,
61 for example, at https://github.com/Lightricks/LTX-2) for the LTX-2
62 model released on January 5, 2026. This license is applicable to

72 2. Grant of License. Subject to the terms and conditions of this
73 Agreement, you are granted a non-exclusive, worldwide,

75 intellectual property or other rights owned by Licensor embodied
76 in LTX-2 to use, reproduce, prepare, distribute, publicly display,
77 publicly perform, sublicense, copy, create derivative works of,
78 and make modifications to LTX-2, for any purpose, subject to the
79 restrictions set forth in Attachment A; provided however, that
80 Entities with annual revenues of at least $10,000,000 (the
81 "Commercial Entities") are required to obtain a paid commercial
82 use license in order to use LTX-2 and Derivatives of LTX-2,
83 subject to the terms and provisions of a different license (the
84 "Commercial Use Agreement"), as will be provided by the Licensor.
85 Commercial Entities interested in such a commercial license are
86 required to contact Licensor. Any commercial use of LTX-2 or
87 Derivatives of LTX-2 by the Commercial Entities not in accordance
88 with this Agreement and/or the Commercial Use Agreement is strictly
89 prohibited and shall be deemed a material breach of this Agreement.
90 Such material breach will be subject, in addition to any license
91 fees owed to Licensor for the period such Commercial Entity used
92 LTX-2 (as will be determined by Licensor), to liquidated damages,
93 which will be paid to Licensor immediately upon demand, in an
94 amount equal to double the amount that would otherwise have been
95 paid by you for the relevant period of time. Such amount reflects
96 a reasonable estimation of the losses and administrative costs

98 remedy does not limit the Licensor's right to pursue other remedies
99 available at law or equity.
100 3. Distribution and Redistribution. You may host for third parties

104 the following conditions:
105 (a) Use-based restrictions as referenced in paragraph 4 and all
106 provisions of Attachment A MUST be included as an enforceable
107 provision by you in any type of legal agreement (e.g. a
108 license) governing the use and/or distribution of LTX-2 or
109 Derivatives of LTX-2, and you shall give notice to subsequent
110 users you distribute to, that LTX-2 or Derivatives of LTX-2
111 are subject to paragraph 4 and Attachment A in their entirety,
112 including all use restrictions and acceptable use policies;
113 (b) You must provide any third party recipients of LTX-2 or

117 weights, modified training code, models trained on Outputs, or
118 any other derivative) must be distributed exclusively under
119 the terms of this Agreement with a complete copy of this
120 license included;
121 (c) You must cause any modified files to carry prominent notices
122 stating that you changed the files;

127 may provide additional or different license terms and conditions -
128 respecting paragraph 3(a) - for use, reproduction, or distribution
129 of your modifications, or for any such Derivatives of LTX-2 as a
130 whole, provided your use, reproduction, and distribution of LTX-2
131 otherwise complies with the conditions stated in this Agreement,
132 and you provide a complete copy of this Agreement with any such
133 use, reproduction and distribution of LTX-2 and any Derivatives
134 thereof.
135 4. Use-based restrictions. The restrictions set forth in Attachment A

137 LTX-2 and the Derivatives of LTX-2 in violation of the specified
138 restricted uses. You may use LTX-2 subject to this Agreement,
139 including only for lawful purposes and in accordance with the
140 Agreement. "Use" may include creating any content with, fine-tuning,

144 5. The Output You Generate. Except as set forth herein, Licensor
145 claims no rights in the Output you generate using LTX-2. You are
146 accountable for input you insert into LTX-2, the Output you
147 generate and its subsequent uses. No use of the Output can
148 contravene any provision as stated in the Agreement.
149 6. Updates and Runtime Restrictions. To the maximum extent permitted
150 by law, Licensor reserves the right to restrict (remotely or

243 prior to termination, including payment obligations under
244 Section 2. In addition, if You commence a lawsuit or other
245 proceedings (including a cross-claim or counterclaim in a lawsuit)
246 against Licensor or any person or entity alleging that LTX-2 or
247 any Output, or any portion of any of the foregoing, infringe any
