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 must cause any modified files to carry prominent notices
stating that You changed the files; You must retain all copyright,
patent, trademark, and attribution notices excluding those notices
