DeepSeek v1.4.2

What is DeepSeek?

DeepSeek is a conversational artificial intelligence assistant developed by the Chinese company Hangzhou DeepSeek Artificial Intelligence Co., Ltd. The app puts its language models within anyone's reach straight from their phone: just type a question or request to get detailed answers, draft texts, clear up doubts or ask for help with code.

What quickly set it apart was its deep reasoning mode, which shows the thought process before giving the final answer, and the fact that it's free. It combines that ability to reason step by step with a web search option that brings in up-to-date information, making it useful for studying and working as well as for handling everyday questions in English.
