DeepSeek has quickly established itself as a prominent player in the competitive landscape of large language model (LLM) development, originating from China with a distinct focus on efficiency and accessibility. Their models are engineered to deliver high performance, often rivalling industry leaders like GPT-4, while simultaneously aiming to minimize computational costs. This is achieved through techniques like Mixture of Experts (MoE) layers, allowing for reduced training expenses. DeepSeek distinguishes itself by releasing "open weight" models, democratizing access to advanced AI technology for developers. Beyond general language capabilities, they've demonstrated notable strength in code generation with their DeepSeek Coder models. While recent reports have highlighted data security concerns, DeepSeek continues to expand its reach with mobile applications and a clear drive to make powerful AI more readily available.
