About company
DeepSeek (深度求索) is a Chinese company founded in 2023, dedicated to making Artificial General Intelligence (AGI) a reality. The company was created by founder Liang Wenfeng, who became a billionaire through his quantitative hedge fund High-Flyer. DeepSeek has disrupted the AI world by releasing its R1 model in January 2025 at a fraction of the cost that other vendors incurred in their developments.
The company focuses on developing open source large language models, providing them under open source licenses for free use. DeepSeek's reasoning models like R1 are specifically developed to engage in extended, deep analysis of complex challenges, with their strength lying in strategic thinking and developing comprehensive solutions.
DeepSeek's success is attributed to using more cost-effective AI architecture, including Mixture-of-Experts (MoE) technique and Multi-head Latent Attention (MLA), which significantly reduce computing costs. The model demonstrates outstanding performance across various benchmark evaluations, including mathematics, programming, and general logic, with overall performance approaching that of leading models such as O3 and Gemini 2.5 Pro.
Within days of its release, the DeepSeek AI assistant mobile app hit the top of Apple's App Store chart, outranking OpenAI's ChatGPT mobile app. The company provides multiple services for its models, including a web interface, mobile application and API access.
