+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,

+
+      "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. 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

+          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;

+       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.

+       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;

+       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 Model Card
+
+This model card focuses on the LTX-2.3 model, which is a significant update to the [LTX-2 model](https://huggingface.co/Lightricks/LTX-2) with improved audio and visual quality as well as enhanced prompt adherence.
+LTX-2 was presented in the paper [LTX-2: Efficient Joint Audio-Visual Foundation Model](https://huggingface.co/papers/2601.03233).
+
+💻💻 **If you want to dive in right to the code - it is available [here](https://github.com/Lightricks/LTX-2).** 💾💾
+
+LTX-2.3 is a DiT-based audio-video foundation model designed to generate synchronized video and audio within a single model. It brings together the core building blocks of modern video generation, with open weights and a focus on practical, local execution.

+## Model Details
+- **Developed by:** Lightricks
+- **Model type:** Diffusion-based audio-video foundation model
+- **Language(s):** English
+
+# Online demo
+LTX-2.3 is accessible right away via the [API Playground](https://console.ltx.video/playground/).
+
+# Run locally
+
+## Direct use license
+You can use the models - full, distilled, upscalers and any derivatives of the models - for purposes under the [license](./LICENSE).
+
+## ComfyUI
+We recommend you use the built-in LTXVideo nodes that can be found in the ComfyUI Manager. 
+For manual installation information, please refer to our [documentation site](https://docs.ltx.video/open-source-model/integration-tools/comfy-ui).
+
+## PyTorch codebase
+
+The [LTX-2 codebase](https://github.com/Lightricks/LTX-2) is a monorepo with several packages. From model definition in 'ltx-core' to pipelines in 'ltx-pipelines' and training capabilities in 'ltx-trainer'.
+The codebase was tested with Python >=3.12, CUDA version >12.7, and supports PyTorch ~= 2.7.
+
+### Installation
+
+```bash
+git clone https://github.com/Lightricks/LTX-2.git
+cd LTX-2
+
+# From the repository root
+uv sync
+source .venv/bin/activate
+```
+
+### Inference
+
+To use our model, please follow the instructions in our [ltx-pipelines](https://github.com/Lightricks/LTX-2/blob/main/packages/ltx-pipelines/README.md) package.
+
+## Diffusers 🧨
+
+LTX-2.3 support in the [Diffusers Python library](https://huggingface.co/docs/diffusers/main/en/index) is coming soon!
+
+## General tips:
+* Width & height settings must be divisible by 32. Frame count must be divisible by 8 + 1. 
+* In case the resolution or number of frames are not divisible by 32 or 8 + 1, the input should be padded with -1 and then cropped to the desired resolution and number of frames.
+* For tips on writing effective prompts, please visit our [Prompting guide](https://ltx.video/blog/how-to-prompt-for-ltx-2) 
+
+### Limitations
+- This model is not intended or able to provide factual information.
+- As a statistical model this checkpoint might amplify existing societal biases.
+- The model may fail to generate videos that matches the prompts perfectly.
+- Prompt following is heavily influenced by the prompting-style.
+- The model may generate content that is inappropriate or offensive.
+- When generating audio without speech, the audio may be of lower quality.
+
+# Train the model
+
+The base (dev) model is fully trainable.
+
+It's extremely easy to reproduce the LoRAs and IC-LoRAs we publish with the model by following the instructions on the [LTX-2 Trainer Readme](https://github.com/Lightricks/LTX-2/blob/main/packages/ltx-trainer/README.md).
+
+Training for motion, style or likeness (sound+appearance) can take less than an hour in many settings.
