DeepSeek is an AI company known for powerful, low-cost, openly available models — including strong reasoning models that rival pricier rivals. Here's what it is, what it's good at, and what to weigh before using it.
DeepSeek is an AI company, based in China, known for building powerful AI models that cost far less than many rivals — and for releasing several of them openly. Its models, including well-regarded reasoning and coding models, made headlines for matching pricier competitors at a fraction of the cost. You can use DeepSeek free through its app and website, much like ChatGPT, and developers can run several of its open models themselves.
For most people, using DeepSeek looks just like any other AI assistant: open the app or site, type a request in plain language, and refine the answer. The same prompting skills apply — give context, a role, a clear task, and the format you want. See how to write a good AI prompt. And as with any model, it can be confidently wrong, so verify important claims.
