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
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
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 License aims to strike a balance
between both in order to enable responsible open-science in the field of
This 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:
1. 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
- "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.
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.
2. 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.
3. 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.
4. 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
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
You must give any Third Party recipients of the Model or Derivatives of
