Welcome to DeepSeek!
DeepSeek products and services are owned and operated by Hangzhou DeepSeek Artificial Intelligence Co., Ltd. (hereinafter referred to as "DeepSeek" or "we"). Before using the Services, please make sure to carefully read and understand this "DeepSeek Terms of Use" (hereinafter referred to as "these Terms") as well as other related terms, policies, or guidelines of this platform. When you use a specific function of the Services, there may be separate terms, related business rules, etc. ("Specific Terms") for that specific function. In the event of any conflict between these Terms and the Specific Terms, the provisions of the Specific Terms shall prevail. All the aforementioned terms and rules form an integral part of these Terms (collectively referred to as "All Terms"), and have the same legal effect as the main text of these Terms.
For detailed rules on how we collect, protect, and use personal information, please carefully read the DeepSeek Privacy Policy. If you would like to learn more about our model mechanism or training methods, please refer to the Model Mechanism and Training Methods of DeepSeek.
We especially remind you to carefully read (minors under the age of 18 or the minimum age required in your country shall read with their legal guardian) and fully understand all the terms before using the Services. When you agree to these Terms through online page clicks, or checking boxes, it means you and we have reached an agreement on All Terms, you have accepted All Terms and their applicable conditions, and agree to be bound by All Terms. If you disagree with any part of these Terms, or cannot accurately understand our interpretation of any term, please click disagree or stop using our services.
1.1 DeepSeek's products and services include those provided to you through websites, applications (which may include different versions), software development kits (SDKs) for third-party websites and applications, application programming interfaces (APIs), and innovative forms that emerge with technological development. These encompass platforms with generative artificial intelligence services at their core, among other functionalities (hereinafter referred to as "the Services").
1.2 The generative AI products and services provided by DeepSeek are based on large language models, which are built using neural network, developed through stages of large-scale self-supervised pre-training and targeted optimization training. These models can predict the next token by encoding and computing the input information (including text, images, files, and more), thereby possessing text generation and conversational abilities. They are adept at performing a wide range of text generation tasks and can be integrated into various downstream systems or applications. Specifically, within DeepSeek's product services, these models, based on user input information (referred to as "Inputs"), compute and infer to output corresponding content as a response (referred to as "Outputs" ), including text, tables, and code. Users can evaluate the output, including actions like liking or disliking, to provide feedback on their opinions about DeepSeek's output information.
1.3 As generative artificial intelligence technology, models, and products continue to evolve, along with changes in laws and regulations, we may add, upgrade, modify, suspend, or terminate services, or make necessary adjustments to the technology, methods, and performance of the services, and may conduct internal or external testing for new service features. If such changes may greatly affect your rights, we will promptly notify you through in-site notifications, website announcements, or via email.
1.4 DeepSeek will take necessary measures (not less than industry practices) to ensure the cyber security and stable operation of the Services. We will also make efforts to enhance and improve technology to ensure a better user experience. If you have any questions or feedback about our services, you can contact us through the method described in Section 11.
1.5 We make no warranty that the Services are available or will continue to be available in certain jurisdictions. The functions or features of the Services may also vary in different jurisdictions.
1.6 Users may also share the Inputs and Outputs information (together referred to as "Dialogues") by generating a unique URL. Anyone who has access to a shared link can view the linked Dialogues. When using such feature, any Dialogues you share with others, if subsequently published on public networks, may be at risk of being obtained by third parties through technical means such as web crawlers. We have implemented industry-standard anti-crawling mechanisms (the robots exclusion protocol) to prevent third parties from scraping user-publicly shared content. However, due to the technical limitations commonly existing within the industry, such risks cannot be entirely eliminated. Therefore, we recommend that you take the following precautions when using this feature: (1) avoid sharing your own or others' personal information, especially sensitive personal data; (2) before sharing other individual's personal information, please ensure you have obtained their explicit consent; (3) before publicly publishing any relevant conversation to an open network, carefully review the content to identify any information you would not wish third parties to access.
2.1 The Services are primarily intended for adults. If you are under 18 years old or the minimum age required in your country, please read these Terms with your legal guardian and use the Services only with the consent of your legal guardian. DeepSeek fully understands the importance of protecting minors and will take corresponding protective measures in accordance with legal requirements and industry mainstream practices.
