+   2. Grant of License.
+
+      2.1 Subject to your compliance with the terms and conditions of
+          this Agreement, you are granted a non-exclusive, worldwide,
+          non-transferable and royalty-free limited license under
+          Licensor's intellectual property or other rights owned by
+          Licensor embodied in LTX-2.x to use, reproduce, prepare,
+          distribute, publicly display, publicly perform, sublicense,
+          copy, create derivative works of, and make modifications to
+          LTX-2.x, for any purpose, subject to the restrictions set
+          forth in Attachment A; provided however, that Entities with
+          annual revenues of at least $10,000,000 (the "Commercial
+          Entities") are required to obtain a paid license for any use
+          (excluding use solely for a Non-Commercial Purpose as set
+          forth in Section 2.2) of LTX-2.x and Derivatives of LTX-2.x
+          (such paid license referred to herein as a "Commercial Use
+          Agreement"), as will be provided by the Licensor. Commercial
+          Entities interested in such a commercial license are required
+          to contact Licensor (ltxv-licensing@lightricks.com). Any use
+          of LTX-2.x or Derivatives of LTX-2.x by 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. In the event of such
+          material breach, and without limiting Licensor's right to
+          terminate the Agreement or to pursue any other remedies
+          available at law or in equity, you shall pay Licensor the
+          license fees owed for the period such Commercial Entity used
+          LTX-2.x (calculated at Licensor's standard commercial license
+          fees, in effect during the relevant period or, absent
+          published standard fees, a reasonable market rate for a
+          comparable license), within thirty (30) days of Licensor's
+          written demand.
+
+      2.2 Notwithstanding the foregoing or anything to the contrary in
+          this Agreement, a Commercial Entity may download and use
+          LTX-2.x and Derivatives of LTX-2.x without obtaining the
+          Commercial Use Agreement solely for a Non-Commercial Purpose.
+          "Non-Commercial Purpose" means any of the following uses, but
+          only so far as such Commercial Entity does not receive any
+          direct or indirect payment arising from the use of LTX-2.x or
+          Derivatives of LTX-2.x: (i) use by an individual acting in a
+          personal capacity for research, experimentation, learning,
+          private study, hobby or recreational projects, or personal
+          entertainment, in each case where such use is not connected,
+          directly or indirectly, to any commercial activity, business
+          operation, or the performance of duties for an employer or any
+          other Entity; and (ii) use by a Commercial Entity for testing,
+          evaluation, or non-commercial research and development in a
+          non-production or development environment. For clarity, use
+          (a) for revenue-generating activity in any manner, whether
+          direct or indirect, (b) in direct interactions with or that
+          has impact on end users, or (c) to train, fine-tune, or
+          distill any model (including any Derivative of LTX-2.x) for
+          commercial use, in each case, is not a Non-Commercial Purpose
+          and requires all Commercial Entities to obtain a paid license
+          under the Commercial Use Agreement prior to such use. For the
+          avoidance of doubt, the permission granted under this Section
+          2.2 is a limited right of use only and does not convey or
+          transfer any ownership right, title, or interest in or to
+          LTX-2.x or any Derivatives of LTX-2.x, and all Derivatives of
+          LTX-2.x created or used pursuant to this Section 2.2 remain
+          subject to the terms of this Agreement, including Section 1.5.
+
+   3. Distribution and Redistribution. You may host for third parties
+      remote access purposes (e.g. software-as-a-service), reproduce and
+      distribute copies of LTX-2.x or Derivatives of LTX-2.x thereof in
+      any medium, with or without modifications, provided that you meet
+      the following conditions:
+
+      3.1 Use-based restrictions as referenced in Section 4 and all
+          provisions of Attachment A MUST be included as an enforceable
+          provision by you in any type of legal agreement (e.g. a
+          license) governing the use and/or distribution of LTX-2.x or
+          Derivatives of LTX-2.x, and you shall give notice to
+          subsequent users you distribute to, that LTX-2.x or
+          Derivatives of LTX-2.x are subject to Section 4 and Attachment
+          A in their entirety, including all use restrictions and
+          acceptable use policies;
+
+      3.2 You must provide any third-party recipients of LTX-2.x or
+          Derivatives of LTX-2.x a copy of this Agreement, including all
+          attachments and use policies. Any Derivative of LTX-2.x (as
+          defined in Section 1.5, including but not limited to
+          fine-tuned weights, modified training code, models trained on
+          Outputs, or any other derivative) must be distributed
+          exclusively under the terms of this Agreement, subject to
+          Section 3.6, with a complete copy of this Agreement included;
+
+      3.3 You must cause any modified files to carry prominent notices
+          stating that you changed the files;
+
+      3.4 You must retain all copyright, patent, trademark, and
+          attribution notices excluding those notices that do not
+          pertain to any part of LTX-2.x, Derivatives of LTX-2.x.
+
+      3.5 Transfer of Derivatives. No transfer of any Derivative of
+          LTX-2.x (including any fine-tuned weights, LoRA adapters, or
+          similar adaptations) to a third party shall grant such third
+          party any right, title, license, or authorization to access,
+          use, reproduce, distribute, or exploit LTX-2.x, or any
+          Derivative of LTX-2.x beyond the rights granted under this
+          Agreement. If the transferee is a Commercial Entity (as
+          defined in Section 2), it must obtain a paid license from
+          Licensor prior to any use of any Derivative of LTX-2.x,
+          regardless of who created such Derivative. Prior to or at the
+          time of any such transfer, you shall notify the transferee in
+          writing that (i) use of such Derivative of LTX-2.x is subject
+          to the terms of this Agreement, and (ii) if the transferee is
+          a Commercial Entity, it must obtain a separate paid license to
+          LTX-2.x from Licensor. You shall not transfer any Derivative
+          of LTX-2.x to a Commercial Entity unless such Commercial
+          Entity has obtained the required paid license from Licensor
+          prior to any use, and unless the proposed transferee has been
+          so informed. You and the transferee shall each be responsible
+          for ensuring the transferee obtains the required license from
+          Licensor prior to any use of LTX-2.x or Derivative of LTX-2.x.
+          Nothing in this Section 3.5 shall require a Commercial Entity
+          to obtain a paid license for use solely for a Non-Commercial
+          Purpose as permitted under Section 2.2.
+
+      3.6 You may add your own copyright statement to your modifications
+          and may provide additional license terms and conditions -
+          respecting Section 3.1 - for use, reproduction, or
+          distribution of your modifications, or for any such
+          Derivatives of LTX-2.x as a whole, provided your use,
+          reproduction, and distribution of LTX-2.x otherwise complies
+          with the conditions stated in this Agreement, and you provide
+          a complete copy of this Agreement with any such use,
+          reproduction and distribution of LTX-2.x and any Derivatives
+          thereof; provided that any such additional terms shall be
+          additive only and shall not derogate from, conflict with,
+          waive, or purport to modify any term of this Agreement, and
+          this Agreement shall govern in the event of any conflict.
+
+   4. Use-based restrictions. The restrictions set forth in Attachment A
+      are considered Use-based restrictions. Therefore, you cannot use
+      LTX-2.x and the Derivatives of LTX-2.x in violation of the
+      specified restricted uses. You may use LTX-2.x subject to this
+      Agreement, only for lawful purposes and in accordance with the
+      Agreement. "Use" may include creating any content with,
+      fine-tuning, updating, running, training, evaluating and/or
+      re-parametrizing LTX-2.x. You shall require all of your users who
+      use LTX-2.x or a Derivative of LTX-2.x to comply with the terms of
+      this Section 4.
+
+   5. The Output You Generate. Except as set forth herein, Licensor
+      claims no rights in the Output you generate using LTX-2.x. You are
+      accountable for input you insert into LTX-2.x, the Output you
+      generate and its subsequent uses. No use of the Output can
+      contravene any provision as stated in the Agreement.
+
+   6. Updates and Runtime Restrictions; AI Regulations. To the maximum
+      extent permitted by law, Licensor reserves the right to restrict
+      (remotely or otherwise) usage of LTX-2.x in violation of this
+      Agreement, update LTX-2.x through electronic means, or modify the
+      Output of LTX-2.x based on updates. You shall undertake reasonable
+      efforts to use the latest version of LTX-2.x. Any use of the
+      non-current version of LTX-2.x is done solely at your risk. To the
+      extent applicable to you, you shall comply with all laws and
+      regulations governing artificial intelligence that apply to your
+      use, deployment, or distribution of LTX-2.x, Derivatives of
+      LTX-2.x, or Outputs, including Regulation (EU) 2024/1689 (the "EU
+      AI Act") and the California AI Transparency Act (Cal. Bus. & Prof.
+      Code § 22757 et seq.), each as amended from time to time and any
+      other applicable laws, regulations, or binding guidance relating
+      to artificial intelligence, transparency, content provenance, or
+      synthetic media, together with any documentation made available by
+      Licensor regarding compliance with the same (collectively, "AI
+      Regulations"). You shall maintain (including within any
+      application or service through which LTX-2.x, any Derivative of
+      LTX-2.x, or any Output is made available), and shall not remove,
+      disable, alter, or circumvent, any safety or security measures,
+      disclosures, metadata, watermarking, content provenance, latent
+      disclosure, or other transparency features or functionalities
+      included or embedded within LTX-2.x or any Derivative of LTX-2.x,
+      or applied to any Output, in furtherance of AI Regulations,
+      including any capability of LTX-2.x to include latent disclosures
+      in Outputs, and you shall include equivalent obligations in any
+      agreement governing your distribution of LTX-2.x or any Derivative
+      of LTX-2.x. You are solely responsible for any transparency,
+      disclosure, marking, or labeling obligations applicable to you
+      under AI Regulations as a provider or deployer of LTX-2.x, any
+      Derivative of LTX-2.x, or any system incorporating any of the
+      foregoing, including any obligation to disclose that content is
+      artificially generated or manipulated. If Licensor knows or
+      reasonably believes that you have modified LTX-2.x or any
+      Derivative of LTX-2.x such that it is no longer capable of
+      including any disclosure required by AI Regulations in Outputs, or
+      that you have otherwise removed, disabled, or circumvented any
+      feature or functionality described in this Section, Licensor may
+      in its sole discretion revoke the license granted under this
+      Agreement effective immediately upon notice to you, and upon such
+      revocation you shall immediately cease all use of LTX-2.x and
+      Derivatives of LTX-2.x. Licensor makes no representation or
+      warranty that LTX-2.x, any Derivative of LTX-2.x, or any Output
+      complies with any AI Regulations applicable to your specific use
+      case or deployment, and you are solely responsible for determining
+      the applicability of, and ensuring your compliance with, all AI
+      Regulations. You shall indemnify, defend, and hold harmless
+      Licensor and its affiliates from and against any and all claims,
+      liabilities, losses, damages, costs, and expenses (including
+      reasonable attorneys' fees) arising out of or relating to your
+      use, deployment, distribution, or modification of LTX-2.x, any
+      Derivative of LTX-2.x, or any Output in violation of, or your
+      other failure to comply with, any AI Regulations.
+
+      For purposes of the EU AI Act, Licensor makes LTX-2.x openly
+      available under this community license and intends that LTX-2.x be
+      treated as a free and open-source general purpose AI model within
+      the meaning of Article 53(2) of the EU AI Act. You acknowledge and
+      agree that (a) to the extent the free and open source derogations
+      under Article 53(2) of the EU AI Act apply, Licensor's obligations
+      under the EU AI Act with respect to LTX-2.x are limited to those
+      applicable to providers of free and open source general purpose AI
+      models (it being acknowledged that such derogations do not extend
+      to the obligations under Article 53(1)(c) and (d)), (b) you
+      acknowledge that LTX-2.x is not intended to be integrated into a
+      high risk AI system, and shall be fully and solely responsible for
+      any obligation resulting from such integration, (c) if you
+      integrate LTX-2.x or any Derivative of LTX-2.x into a high-risk AI
+      system you shall be solely responsible for all provider
+      obligations that would otherwise apply to Licensor under the EU AI
+      Act, and (d) you shall not take any action, or omit to take any
+      action, that would cause Licensor to lose the benefit of the free
+      and open source derogations under the EU AI Act, and you shall
+      indemnify and hold Licensor harmless from any liability, costs, or
+      expenses arising from your breach of this Section.
+
+   7. Export Controls and Sanctions Compliance. You acknowledge that
+      LTX-2.x, Derivatives of LTX-2.x may be subject to export control
+      laws and regulations, including but not limited to the U.S. Export
+      Administration Regulations and sanctions programs administered by
+      the Office of Foreign Assets Control (OFAC). You represent and
+      warrant that you and any users of LTX-2.x are not (i) located in,
+      organized under the laws of, or ordinarily resident in any country
+      or territory subject to comprehensive sanctions; (ii) identified
+      on any U.S. government restricted party list, including the
+      Specially Designated Nationals and Blocked Persons List; or (iii)
+      otherwise prohibited from receiving LTX-2.x under applicable law.
+      You shall not export, re-export, or transfer LTX-2.x, directly or
+      indirectly, in violation of any applicable export control or
+      sanctions laws or regulations. You agree to comply with all
+      applicable trade control laws and shall indemnify and hold
+      Licensor harmless from any claims arising from your failure to
+      comply with such laws.
+
+   8. Trademarks; Reservation of Rights. Nothing in this Agreement
+      permits you to make use of Licensor's trademarks, trade names,
+      logos or to otherwise suggest endorsement or misrepresent the
+      relationship between the parties; and any rights not expressly
+      granted herein are reserved by the Licensor. Except as expressly
+      set forth in this Agreement, Licensor does not grant, directly or
+      by implication, estoppel, statute or otherwise, any right or
+      license in its, or its affiliates', intellectual property rights
+      or other proprietary rights. For avoidance of doubt, all
+      intellectual property rights in Derivatives of LTX-2.x shall be
+      subject to the terms of this Agreement, and you acquire no right,
+      title, or interest in or to LTX-2.x itself, which is and remains
+      the exclusive property of Licensor. You shall not assert any
+      ownership or other right in LTX-2.x or any Derivative of LTX-2.x
+      in any manner that restricts, encumbers, or is inconsistent with
+      the rights retained by Licensor or granted to other licensees
+      under this Agreement.
+
+   9. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides LTX-2.x on an "AS IS"
+      BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either
+      express or implied, including, without limitation, any warranties
+      or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or
+      FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for
+      determining the appropriateness of using or redistributing LTX-2.x
+      and Derivatives of LTX-2.x and assume any risks associated with
+      your exercise of permissions under this Agreement.
+
+   10. Limitation of Liability. To the fullest extent permitted by
+       applicable law, in no event and under no legal theory, whether in
+       tort (including negligence), contract, or otherwise, unless
+       required by applicable law (such as deliberate and grossly
+       negligent acts) or agreed to in writing, shall Licensor be liable
+       to you or any other individual or Entity for damages, including
+       any direct, indirect, special, incidental, or consequential
+       damages of any character arising as a result of this Agreement or
+       out of the use of, or inability to use LTX-2.x or any Derivative
+       of LTX-2.x (including but not limited to damages for loss of
+       goodwill, work stoppage, computer failure or malfunction, or any
+       and all other commercial damages or losses), even if Licensor has
+       been advised of the possibility of such damages.
+
+   11. Accepting Warranty or Additional Liability. While redistributing
+       LTX-2.x and Derivatives of LTX-2.x, you may, provided you do not
+       violate the terms of this Agreement, choose to offer and charge a
+       fee for, acceptance of support, warranty, indemnity, or other
+       liability obligations. However, in accepting such obligations,
+       you may act only on your own behalf and on your sole
+       responsibility, not on behalf of Licensor, and only if you agree
+       to indemnify, defend, and hold Licensor harmless for any
+       liability incurred by, or claims asserted against Licensor, by
+       reason of your accepting any such warranty or additional
+       liability.
+
+   12. Governing Law. This Agreement and all relations, disputes, claims
+       and other matters arising hereunder (including non-contractual
+       disputes or claims) will be governed exclusively by, and
+       construed exclusively in accordance with, the laws of the State
+       of New York and applicable U.S. federal law. To the extent
+       permitted by law, choice of laws rules and the United Nations
+       Convention on Contracts for the International Sale of Goods will
+       not apply. The prevailing party in any claim or dispute between
+       the parties under this Agreement will be entitled to
+       reimbursement of its reasonable attorneys' fees and costs.
+
+   13. Term and Termination. This Agreement is effective upon your
+       acceptance and continues until terminated. Licensor may terminate
+       this Agreement immediately upon written notice to you if you
+       breach any provision of this Agreement, including but not limited
+       to violations of the use restrictions in Attachment A or
+       unauthorized commercial use. This Agreement also terminates
+       immediately and automatically, without notice, upon any material
+       breach of this Agreement, including any use in violation of
+       applicable AI Regulations or any unauthorized commercial use of
+       LTX-2.x or Derivatives of LTX-2.x by a Commercial Entity. Upon
+       termination: (a) all rights granted to you under this Agreement
+       will immediately cease; (b) you must immediately cease all use of
+       LTX-2.x and Derivatives of LTX-2.x; (c) you must delete or
+       destroy all copies of LTX-2.x and Derivatives of LTX-2.x in your
+       possession or control; and (d) you must notify any third parties
+       to whom you distributed LTX-2.x or Derivatives of LTX-2.x of the
+       termination. Sections 2, 3, 4, 6-16 and Attachment A shall
+       survive termination of this Agreement. Termination does not
+       relieve you of any obligations incurred prior to termination,
+       including payment obligations under Section 2 and adhering to the
+       restrictions under Section 3. In addition, if You commence a
+       lawsuit or other proceedings (including a cross-claim or
+       counterclaim in a lawsuit) against Licensor or any person or
+       entity alleging that LTX-2.x or any Output, or any portion of any
+       of the foregoing, infringe any intellectual property or other
+       right owned or licensable by you, then all licenses granted to
+       you under this Agreement shall terminate as of the date such
+       lawsuit or other proceeding is filed.
+
+   14. Disputes and Arbitration; Waiver of Jury Trial; Class Action
+       Waiver. IF YOU ARE NOT ACTING AS A CONSUMER UNDER APPLICABLE LAW,
+       YOU HEREBY WAIVE THE RIGHT TO A TRIAL BY JURY, TO PARTICIPATE IN
+       A CLASS OR REPRESENTATIVE ACTION (INCLUDING IN ARBITRATION), OR
+       TO COMBINE INDIVIDUAL PROCEEDINGS IN COURT OR IN ARBITRATION
+       WITHOUT THE CONSENT OF ALL PARTIES. All disputes arising in
+       connection with this Agreement shall be finally settled by
+       arbitration under the Rules of Arbitration of the International
+       Chamber of Commerce ("ICC Rules"), by one (1) arbitrator
+       appointed in accordance with the ICC Rules. The seat of
+       arbitration shall be New York, NY, USA, and the proceedings shall
+       be conducted in English. The arbitrator shall be empowered to
+       grant any relief that a court could grant. Judgment on the
+       arbitration award may be entered by any court having jurisdiction
+       thereof. Notwithstanding the foregoing, either party may seek
+       injunctive or other equitable relief in respect of any actual or
+       threatened breach of the license restrictions under this
+       Agreement (including Attachment A and the Acceptable Use Policy)
+       or any actual or threatened infringement, misappropriation, or
+       violation of Licensor's intellectual property rights, in the
+       state or federal courts located in the County of New York, State
+       of New York, and each party irrevocably consents to the
+       jurisdiction of, and venue in, such courts for that limited
+       purpose. The foregoing waivers do not apply to, and are not
+       enforceable against, any licensee acting as a consumer under the
+       mandatory consumer-protection laws of its jurisdiction of
+       residence (including, without limitation, the European Union, the
+       United Kingdom, and the State of California), and nothing in this
+       Agreement limits any rights under such laws that cannot be waived
+       or limited by contract. If any waiver in this Section is held
+       invalid or unenforceable as to a particular licensee or dispute,
+       such waiver shall be severed to that extent only and shall not
+       affect the validity or enforceability of the remainder of this
+       Section.
+
+   15. In the event of any exception to the application of binding
+       arbitration, all disputes, claims, and other matters arising
+       hereunder shall be brought exclusively in the state or federal
+       courts located in the County of New York, State of New York. You
+       waive all defenses of lack of personal jurisdiction and forum non
+       conveniens with respect to venue and jurisdiction in such courts,
+       and consent to their exclusive jurisdiction and venue.
+
+   16. Severability. If any provision of this Agreement is held to be
+       invalid, illegal or unenforceable, the remaining provisions shall
+       be unaffected thereby and remain valid as if such provision had
+       not been set forth herein.
+
+                      END OF TERMS AND CONDITIONS                       
+

+## LTX-2.5
 
-WanGP by DeepBeepMeep : The best Open Source Video Generative Models Accessible to the GPU Poor
+WanGP provides LTX-2.5 Dev and Distilled in BF16 and INT8 ConvRot, plus the official Distilled NVFP4 variant. Large upstream bundles are split into independently offloadable transformer, Gemma 4, text-projection, video/audio connector, VAE, vocoder, and upscaler files. Dev and Distilled share connector files only where their tensors were verified identical; NVFP4 has checkpoint-specific connectors.
 
-WanGP supports the Wan (and derived models), Hunyuan Video, Flux 1 & 2, Qwen, Z-Image and LTV Video models with:
+See [LTX-2.5-MANIFEST.md](LTX-2.5-MANIFEST.md) for the runtime file map and [LICENSE-LTX-2.5.txt](LICENSE-LTX-2.5.txt) for the upstream license. The split files preserve the original tensor values; their metadata records the WanGP packaging modification.
 
-Low VRAM requirements (as low as 6 GB of VRAM is sufficient for certain models)
-Support for old GPUs (RTX 10XX, 20xx, ...)
-Very Fast on the latest GPUs
-Easy to use Full Web based interface
-Auto download of the required model adapted to your specific architecture
-Tools integrated to facilitate Video Generation : Mask Editor, Prompt Enhancer, Temporal and Spatial Generation
-Loras Support to customize each model
-Queuing system : make your shopping list of videos to generate and come back later
-Discord Server to get Help from Other Users and show your Best Videos: https://discord.gg/g7efUW9jGV
+WanGP by DeepBeepMeep makes leading open-source video generative models accessible to the GPU poor, with low VRAM modes, support for older GPUs, automatic model downloads, queues, integrated media tools, and LoRA workflows.
