For the current stage of AI large models, how they can be deployed and utilized across various industries has become a topic of increasing interest. My friend raised several questions: In addition to extracting relevant information from knowledge bases, what other functions does DeepSeek serve? Are there specific case studies where such AI technologies have been integrated with real industries, for example, in the mechanical and electronics engineering sector?

Reflecting on these questions, I conducted a study and analysis based on DeepSeek’s open-source projects and documentation.

Firstly, AI models like DeepSeek are capable of more than just extracting information from databases. They can perform knowledge reasoning, generate text, and demonstrate strong capabilities in areas such as computer vision, natural language processing, code generation, and intelligent application development. Within the mechanical and electronics engineering industry, AI technologies can be applied for fault diagnosis, production process optimization, and product design assistance. For instance, analyzing equipment data to predict potential failures or optimizing production line scheduling to enhance efficiency while reducing safety risks for personnel.
