+                         LTX-2 Community License Agreement
+                           License date: January 5, 2026
+
+
+By using or distributing any portion or element of LTX-2, you agree
+to be bound by this Agreement.
+
+   1. Definitions.
+
+      "Agreement" means the terms and conditions for the license, use,
+      reproduction, and distribution of LTX-2 and the Complementary
+      Materials, as specified in this document.
+
+      "Control" means the direct or indirect ownership of fifty percent
+      (50%) or more of the voting securities or other ownership
+      interests, or the power to direct the management and policies of
+      such Entity through voting rights, contract, or otherwise.
+
+      "Data" means a collection of information and/or content extracted
+      from the dataset used with LTX-2, including to train, pretrain,
+      or otherwise evaluate LTX-2. The Data is not licensed under this
+      Agreement.
+
+      "Derivatives of LTX-2" means all modifications to LTX-2, works
+      based on LTX-2, or any other model which is created or initialized
+      by transfer of patterns of the weights, parameters, activations or
+      output of LTX-2, to the other model, in order to cause the other
+      model to perform similarly to LTX-2, including – but not limited
+      to - distillation methods entailing the use of intermediate data
+      representations or methods based on the generation of synthetic
+      data by LTX-2 for training the other model. For clarity, Derivatives
+      of LTX-2 include: (i) any fine-tuned or adapted weights, parameters,
+      or checkpoints derived from LTX-2; (ii) derivative model architectures
+      that incorporate or are based upon LTX-2's architecture; and
+      (iii) any modified or extended versions of the Complementary
+      Materials. All intellectual property rights in Derivatives of LTX-2
+      shall be subject to the terms of this Agreement, and you may not
+      claim exclusive ownership rights in any Derivatives of LTX-2 that
+      would restrict the rights granted herein.
+
+      "Entity" means any individual, corporation, partnership, limited
+      liability company, or other legal entity. For purposes of this
+      Agreement, an Entity shall be deemed to include, on an aggregative
+      basis, all subsidiaries, affiliates, and other companies under
+      common Control with such Entity. When determining whether an Entity
+      meets any threshold under this Agreement (including revenue
+      thresholds), all subsidiaries, affiliates, and companies under
+      common Control shall be considered collectively.
+
+      "Harm" includes but is not limited to physical, mental,
+      psychological, financial and reputational damage, pain, or loss.
+
+      "Licensor" or "Lightricks" means the owner that is granting the
+      license under this Agreement. For the purposes of this Agreement,
+      the Licensor is Lightricks Ltd.
+
+      "LTX-2" means the large language models, text/image/video/audio/3D
+      generation models, and multimodal large language models and their
+      software and algorithms, including trained model weights, parameters
+      (including optimizer states), machine-learning model code,
+      inference-enabling code, training-enabling code, fine-tuning
+      enabling code, accompanying source code, scripts, documentation,
+      tutorials, examples, and all other elements of the foregoing
+      distributed and made publicly available by Lightricks (including,
+      for example, at https://github.com/Lightricks/LTX-2) for the LTX-2
+      model released on January 5, 2026. This license is applicable to
+      all LTX-2 versions released since January 5, 2026, and all future
+      releases of LTX-2 under this license.
+
+      "Output" means the results of operating LTX-2 as embodied in
+      informational content resulting therefrom.
+
+      "you" (or "your") means an individual or legal Entity licensing
+      LTX-2 in accordance with this Agreement and/or making use of LTX-2
+      for whichever purpose and in any field of use, including usage of
+      LTX-2 in an end-use application - e.g. chatbot, translator, image
+      generator.
+
+   2. Grant of License. Subject to 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 to use, reproduce, prepare, distribute, publicly display,
+      publicly perform, sublicense, copy, create derivative works of,
+      and make modifications to LTX-2, 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 commercial
+      use license in order to use LTX-2 and Derivatives of LTX-2,
+      subject to the terms and provisions of a different license (the
+      "Commercial Use Agreement"), as will be provided by the Licensor.
+      Commercial Entities interested in such a commercial license are
+      required to [contact Licensor](https://ltx.io/model/licensing). 
+      Any commercial use of LTX-2 or Derivatives of LTX-2 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 material breach will be subject, in addition to any license
+      fees owed to Licensor for the period such Commercial Entity used
+      LTX-2 (as will be determined by Licensor), to liquidated damages,
+      which will be paid to Licensor immediately upon demand, in an
+      amount equal to double the amount that would otherwise have been
+      paid by you for the relevant period of time. 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.
+
+   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 or Derivatives of LTX-2 thereof in
+      any medium, with or without modifications, provided that you meet
+      the following conditions:
+
+      (a) Use-based restrictions as referenced in paragraph 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 or
+          Derivatives of LTX-2, and you shall give notice to subsequent
+          users you distribute to, that LTX-2 or Derivatives of LTX-2
+          are subject to paragraph 4 and Attachment A in their entirety,
+          including all use restrictions and acceptable use policies;
+
+      (b) You must provide any third party recipients of LTX-2 or
+          Derivatives of LTX-2 a copy of this Agreement, including all
+          attachments and use policies. Any Derivative of LTX-2 (as
+          defined in Section 1, 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 with a complete copy of this
+          license included;
+
+      (c) You must cause any modified files to carry prominent notices
+          stating that you changed the files;
+
+      (d) You must retain all copyright, patent, trademark, and
+          attribution notices excluding those notices that do not
+          pertain to any part of LTX-2, Derivatives of LTX-2.
+
+      You may add your own copyright statement to your modifications and
+      may provide additional or different license terms and conditions -
+      respecting paragraph 3(a) - for use, reproduction, or distribution
+      of your modifications, or for any such Derivatives of LTX-2 as a
+      whole, provided your use, reproduction, and distribution of LTX-2
+      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 and any Derivatives
+      thereof.
+
+   4. Use-based restrictions. The restrictions set forth in Attachment A
+      are considered Use-based restrictions. Therefore, you cannot use
+      LTX-2 and the Derivatives of LTX-2 in violation of the specified
+      restricted uses. You may use LTX-2 subject to this Agreement,
+      including 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. You shall require all of your users who use LTX-2 or a
+      Derivative of LTX-2 to comply with the terms of this paragraph 4.
+
+   5. The Output You Generate. Except as set forth herein, Licensor
+      claims no rights in the Output you generate using LTX-2. You are
+      accountable for input you insert into LTX-2, 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. To the maximum extent permitted
+      by law, Licensor reserves the right to restrict (remotely or
+      otherwise) usage of LTX-2 in violation of this Agreement, update
+      LTX-2 through electronic means, or modify the Output of LTX-2
+      based on updates. You shall undertake reasonable efforts to use
+      the latest version of LTX-2. Any use of the non-current version
+      of LTX-2 is done solely at your risk.
+
+   7. Export Controls and Sanctions Compliance. You acknowledge that
+      LTX-2, Derivatives of LTX-2 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 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 under applicable
+      law. You shall not export, re-export, or transfer LTX-2, 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 and related. 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.
+
+   9. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides LTX-2 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
+      and Derivatives of LTX-2 and assume any risks associated with
+      your exercise of permissions under this Agreement.
+
+   10. Limitation of Liability. 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 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 or inability to use
+       LTX-2 (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 and Derivatives of LTX-2, 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.
+       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. For the purposes of adjudicating any
+       action or proceeding to enforce the terms of this Agreement, you
+       hereby irrevocably consent to the exclusive jurisdiction of, and
+       venue in, the federal and state courts located in the County of
+       New York within the State of New York. 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. 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.
+
+   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. Upon termination: (a) all rights
+       granted to you under this Agreement will immediately cease;
+       (b) you must immediately cease all use of LTX-2 and Derivatives
+       of LTX-2; (c) you must delete or destroy all copies of LTX-2
+       and Derivatives of LTX-2 in your possession or control; and
+       (d) you must notify any third parties to whom you distributed
+       LTX-2 or Derivatives of LTX-2 of the termination. Sections 8-13,
+       and Section 15 shall survive termination of this Agreement.
+       Termination does not relieve you of any obligations incurred
+       prior to termination, including payment obligations under
+       Section 2. 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 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. 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. Each party waives its right to a
+       trial by jury and to participate in any class or representative
+       action.
+
+   15. 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.

+# ltx-2.3-mlx — bf16 components + distilled transformer
+
+**A verbatim availability mirror.** Full-precision LTX-2.3 components (connector, video/audio VAEs, vocoder, spatial upscaler) plus the bf16 distilled transformer.
+
+## Why this repo exists
+
+This is an unmodified mirror of [`dgrauet/ltx-2.3-mlx`](https://huggingface.co/dgrauet/ltx-2.3-mlx),
+hosted so that downstream software has a weight source that does not depend on a third-party
+namespace remaining available. It exists for **durability, not improvement** — there is nothing
+here you cannot get upstream, and upstream is the better place to get it if you want the
+newest revision.
+
+The motivation is concrete rather than hypothetical: an unrelated model family we ship ports
+of was relocated to a new organization without HTTP redirects, and every published package
+referencing the old paths broke the same day. Availability is a dependency like any other.
+
+## Provenance chain
+
+| Stage | Who | What |
+|---|---|---|
+| Original weights | **Lightricks** | [LTX-2](https://huggingface.co/Lightricks/LTX-2) — a DiT-based joint audio+video model. All model IP is theirs. |
+| MLX conversion | **dgrauet** | Converted to MLX format with [mlx-forge](https://github.com/dgrauet/mlx-forge); published as [`dgrauet/ltx-2.3-mlx`](https://huggingface.co/dgrauet/ltx-2.3-mlx) alongside the [ltx-2-mlx](https://github.com/dgrauet/ltx-2-mlx) inference pipeline. |
+| This mirror | xocialize | **Byte-for-byte copy. No modification of any kind.** |
+
+**We did not convert, quantize, fine-tune, or otherwise alter these weights.** Every tensor
+file here was verified by SHA-256 against the corresponding upstream file at mirror time; the
+hashes are listed below so anyone can check that claim independently.
+
+Small JSON metadata files were taken fresh from upstream at mirror time and may therefore carry
+metadata additions relative to an older local copy; the tensor files are the verified artifacts.
+
+## Licence — read this before use
+
+These weights are governed by the **LTX-2 Community License Agreement** (dated January 5, 2026),
+included in full as [`LICENSE`](LICENSE) in this repository. Mirroring does not alter, relax, or
+re-license anything.
+
+Two obligations deserve to be called out explicitly, because they are easy to miss and they bind
+*you* as a user of these weights, not just us as a distributor:
+
+1. **Use-based restrictions (paragraph 4 and Attachment A) apply in their entirety.** Attachment A
+   is an enforceable part of the licence and lists prohibited uses. You must comply with it, and
+   you must require the same of anyone you distribute to.
+2. **Attachment A item 20 is a non-compete.** Using LTX-2 or its derivatives in a product or
+   service that competes with, replaces, or substitutes Lightricks' commercial offerings requires
+   a separate commercial licence from Lightricks. There is also a revenue threshold in the
+   agreement's commercial terms. If you are building a product, read the licence yourself rather
+   than relying on this summary.
+
+Any redistribution of these weights or derivatives of them must carry a complete copy of the
+agreement and propagate these terms (§3). This summary is a courtesy pointer, **not** a substitute
+for the licence text, and where the two differ the licence governs.
