Hangzhou DeepSeek, a Chinese artificial intelligence firm based in Hangzhou, specializes in developing open-source large language models. Established recently by Liang Wenfeng, the company has made waves in the tech sector for its latest AI developments. Impressively, DeepSeek claims to produce AI comparable to leading models like GPT-4 at a fraction of the cost and computing power. This achievement is particularly remarkable given the US sanctions on China for Nvidia processors, showcasing DeepSeek's technological prowess in the competitive AI landscape.
