Hangzhou DeepSeek, a Chinese AI company based in Hangzhou, focuses on developing open-source large language models. Established recently by Liang Wenfeng, the company has gained attention in the tech sector for its DeepSeek-R1 model. Impressively, DeepSeek claims to produce AI rivaling leading models like GPT-4 at a fraction of the cost and resource requirements. This breakthrough is particularly noteworthy given the US sanctions on China for advanced AI chips, demonstrating DeepSeek's technological prowess in the competitive AI landscape.
