DeepSeek is an AI research company providing a suite of powerful large language models, including a world-class coder model and a conversational AI, accessible via a free chat interface and a competitively-priced API.

Try it out

DeepSeek develops high-performance, open-source large language models for a global audience of developers, researchers, and general users. Its product suite is headlined by DeepSeek Coder, a specialized model trained on billions of lines of code, and DeepSeek-V2, a general-purpose conversational AI. The primary value proposition lies in offering state-of-the-art AI performance, particularly in coding, at a fraction of the cost of mainstream competitors. Users can interact with the models for free through a web-based chat or integrate them into applications via a highly affordable pay-as-you-go API. This combination of open-source spirit, top-tier performance, and disruptive pricing makes it a compelling alternative to established AI platforms.
