Overview
DeepSeek is a hosted chat service for general questions, coding, reasoning, document work, and related model-assisted tasks. The official website links the web chat, API platform, documentation, downloads, and research releases, while the service is accessed through DeepSeek’s own accounts and interfaces. DeepSeek also publishes official model repositories, including DeepSeek-V3, with code for local inference under an MIT license. The hosted chat application itself remains closed source, so the public model repository should not be treated as the source of the full web product.
