DeepSeek-V3/LICENSE-MODEL

DEEPSEEK LICENSE AGREEMENT

Version 1.0, 23 October 2023

Copyright (c) 2023 DeepSeek

Section I: PREAMBLE 

Large generative models are being widely adopted and used, and have the 
potential to transform the way individuals conceive and benefit from AI or ML 
technologies. 

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 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 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 DeepSeek 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 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. 
"DeepSeek" (or "we") means Beijing DeepSeek Artificial Intelligence Fundamental 
Technology Research Co., Ltd., Hangzhou DeepSeek Artificial Intelligence 
Fundamental Technology Research Co., Ltd. and/or any of their affiliates.
"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, etc. 
"Third Parties" means individuals or legal entities that are not under common 
control with DeepSeek or You. 

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. 

2. Grant of Copyright License. Subject to the terms and conditions of this 
License, DeepSeek 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, DeepSeek 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 
DeepSeek that are necessarily infringed by its contribution(s). 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 constitutes direct or contributory patent infringement, then any 
patent licenses granted to You under this License for the Model and/or works 
shall terminate as of the date such litigation is asserted or filed. 


Section III: CONDITIONS OF USAGE, DISTRIBUTION AND REDISTRIBUTION

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
