DeepSeek is an AI company offering large language models through a web chat, mobile app, desktop application and API. It also publishes model weights on Hugging Face: DeepSeek-V3.2 is released under the MIT licence, while the earlier DeepSeek-V3 weights fall under a separate model licence. The weights can be downloaded and run on a customer's own infrastructure.
The operating entity is Hangzhou DeepSeek Artificial Intelligence Co., Ltd., based in China, with no EU or US parent. Its privacy policy states that personal data collected through its services is stored in the People's Republic of China and may be shared with public authorities in limited legal cases; it names a representative for EU and UK data-subject requests. For a European organisation, the hosted chat or API therefore means data going to servers in China, while running the openly licensed weights on its own EU infrastructure keeps data under its own control. The hosted service is proprietary.
