What are the key features and challenges of the Chinese AI chatbot Deepseek?

Deepseek stands out primarily because it's free to use with open-source code that anyone can download and build upon. This strategic approach has created competitive pressure on both domestic and international competitors to offer their own AI services for free. The chatbot has sparked national pride with its rapid technological development, with one user expressing how China's fast-advancing technology makes them feel proud. Despite its popularity, Deepseek faces challenges with universal acceptance, as some countries have expressed concerns about the application.
