What is DeepSeek?

DeepSeek is an AI chat assistant developed by the Chinese company DeepSeek. Through its website and mobile apps, you can ask questions, write and edit text, solve math problems and get help with code. It is popular with students, developers and users looking for a capable assistant that is free to use. A reasoning mode, labeled DeepThink, shows the model working through a problem step by step before answering, which helps with math, logic and programming questions. DeepSeek also releases open-weight models and offers a developer API, so the same technology can be used in other applications.
