DeepSeek secrets unveiled: engineers reveal science behind China’s viral AI model
The team uses rewards to teach the AI to solve problems, allowing them to bypass conventional training barriers

Upon its release in January, the open-source model developed by Hangzhou-based AI start-up DeepSeek sent shock waves through the industry when it became a challenger to US-based OpenAI’s industry-leading o1 model.
“General reasoning represents a long-standing and formidable challenge in artificial intelligence,” the team said in a paper published in the peer-reviewed journal Nature on Wednesday.
Reasoning, or the logical process of using existing knowledge and new information to form conclusions, is a cornerstone of human cognition.
It allows for the execution of complex cognitive tasks, including mathematical problem solving, making it a key element in developing more advanced, humanlike AI.
