+Section I: PREAMBLE Multimodal generative models are being widely adopted and used, and
+have the potential to transform the way artists, among other individuals, conceive and
+benefit from AI or ML technologies as a tool for content creation. Notwithstanding the
+current and potential benefits that these artifacts can bring to society at large, there
+are also concerns about potential misuses of them, either due to their technical
+limitations or ethical considerations. In short, this license strives for both the open
+and responsible downstream use of the accompanying model. When it comes to the open
+character, we took inspiration from open source permissive licenses regarding the grant
+of IP rights. Referring to the downstream responsible use, we added use-based
+restrictions not permitting the use of the model in very specific scenarios, in order
+for the licensor to be able to enforce the license in case potential misuses of the
+Model may occur. At the same time, we strive to promote open and responsible research on
+generative models for art and content generation. Even though downstream derivative
+versions of the model could be released under different licensing terms, the latter will
+always have to include - at minimum - the same use-based restrictions as the ones in the
+original license (this license). We believe in the intersection between open and
+responsible AI development; thus, this agreement aims to strike a balance between both
+in order to enable responsible open-science in the field of AI. This CreativeML Open
+RAIL++-M License governs the use of the model (and its derivatives) and is informed by
+the model card associated with the model. NOW THEREFORE, You and Licensor agree as
+follows: Definitions "License" means the terms and conditions for use, reproduction, and
+Distribution as defined in this document. "Data" means a collection of information
+and/or content extracted from the dataset used with the Model, including to train,
+pretrain, or otherwise evaluate the Model. The Data is not licensed under this License.
+"Output" means the results of operating a Model as embodied in informational content
+resulting therefrom. "Model" means any accompanying machine-learning based assemblies
+(including checkpoints), consisting of learnt weights, parameters (including optimizer
+states), corresponding to the 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. "Derivatives of the Model" means all modifications to the Model,
+works based on the Model, or any other model which is created or initialized by transfer
+of patterns of the weights, parameters, activations or output of the Model, to the other
+model, in order to cause the other model to perform similarly to the Model, including -
+but not limited to - distillation methods entailing the use of intermediate data
+representations or methods based on the generation of synthetic data by the Model for
+training the other model. "Complementary Material" means the accompanying source code
+and scripts used to define, run, load, benchmark or evaluate the Model, and used to
+prepare data for training or evaluation, if any. This includes any accompanying
+documentation, tutorials, examples, etc, if any. "Distribution" means any transmission,
+reproduction, publication or other sharing of the Model or Derivatives of the Model to a
+third party, including providing the Model as a hosted service made available by
+electronic or other remote means - e.g. API-based or web access. "Licensor" means the
+copyright owner or entity authorized by the copyright owner that is granting the
+License, including the persons or entities that may have rights in the Model and/or
+distributing the Model. "You" (or "Your") means an individual or Legal Entity exercising
+permissions granted by this License and/or making use of the Model for whichever purpose
+and in any field of use, including usage of the Model in an end-use application - e.g.
+chatbot, translator, image generator. "Third Parties" means individuals or legal
+entities that are not under common control with Licensor or You. "Contribution" means
+any work of authorship, including the original version of the Model and any
+modifications or additions to that Model or Derivatives of the Model thereof, that is
+intentionally submitted to Licensor for inclusion in the Model by the copyright owner or
+by an individual or Legal Entity authorized to submit on behalf of the copyright owner.
+For the purposes of this definition, "submitted" means any form of electronic, verbal,
+or written communication sent to the Licensor or its representatives, including but not
+limited to communication on electronic mailing lists, source code control systems, and
+issue tracking systems that are managed by, or on behalf of, the Licensor for the
+purpose of discussing and improving the Model, but excluding communication that is
+conspicuously marked or otherwise designated in writing by the copyright owner as "Not a
+Contribution." "Contributor" means Licensor and any individual or Legal Entity on behalf
+of whom a Contribution has been received by Licensor and subsequently incorporated
+within the Model.

+Section III. Grant of Copyright License. Subject to the terms and conditions of this
+License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive,
+no-charge, royalty-free, irrevocable copyright license to reproduce, prepare, publicly
+display, publicly perform, sublicense, and distribute the Complementary Material, the

+that are necessarily infringed by their Contribution(s) alone or by combination of their
+Contribution(s) with the Model to which such Contribution(s) was submitted. If You
+institute patent litigation against any entity (including a cross-claim or counterclaim
+in a lawsuit) alleging that the Model and/or Complementary Material or a Contribution
+incorporated within the Model and/or Complementary Material constitutes direct or
