Copyright (c) 2023 Stability AI CreativeML Open RAIL++-M License dated July 26, 2023

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 II: INTELLECTUAL PROPERTY RIGHTS Both copyright and patent grants apply to the
Model, Derivatives of the Model and Complementary Material. The Model and Derivatives of
the Model are subject to additional terms as described in

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
Model, and Derivatives of the Model. Grant of Patent License. Subject to the terms and
conditions of this License and where and as applicable, each Contributor hereby grants
to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this paragraph) patent license to make, have made, use, offer to
sell, sell, import, and otherwise transfer the Model and the Complementary Material,
where such license applies only to those patent claims licensable by such Contributor
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
contributory patent infringement, then any patent licenses granted to You under this
License for the Model and/or Work shall terminate as of the date such litigation is
asserted or filed. Section III: CONDITIONS OF USAGE, DISTRIBUTION AND REDISTRIBUTION
Distribution and Redistribution. You may host for Third Party remote access purposes
(e.g. software-as-a-service), reproduce and distribute copies of the Model or
Derivatives of the Model thereof in any medium, with or without modifications, provided
that You meet the following conditions: Use-based restrictions as referenced in
paragraph 5 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 the Model or
Derivatives of the Model, and You shall give notice to subsequent users You Distribute
to, that the Model or Derivatives of the Model are subject to paragraph 5. This
provision does not apply to the use of Complementary Material. You must give any Third
Party recipients of the Model or Derivatives of the Model a copy of this License; You
