What is DeepSeek?

This is the DeepSeek most people mean: the free chat app and website that briefly topped global download charts and made the Chinese lab a household name. Underneath sits DeepSeek's latest flagship model, with a DeepThink reasoning mode for maths, logic and coding, plus web search and file uploads — a combination that rivals paid assistants while carrying no subscription price.

The chat is free with generous limits, though demand spikes have caused slowdowns and occasional service restrictions, and sign-up routes vary by region. Data is stored on servers in China, which privacy-conscious users and regulated companies should weigh carefully. Developers who outgrow the chat can move to DeepSeek's low-cost API, while the models' open weights power countless third-party apps.
