On September 17, 2025, China's artificial intelligence (AI) landscape witnessed a momentous breakthrough. Liang Wenfeng, along with his teammates from the DeepSeek-AI group, unveiled their research on the open-source model DeepSeek-R1 in the prestigious journal 'Nature', with their paper earning the coveted cover spot for that edition.

The research presents compelling evidence that large-scale reasoning models can be effectively trained through pure reinforcement learning. This approach not only boosts the reasoning prowess of large language models but also minimizes their dependence on human-generated data. The model demonstrated exceptional performance in graduate-level tasks across mathematics, programming contests, and STEM disciplines. In mathematical benchmark assessments, it scored an impressive 77.9% (DeepSeek-R1-Zero) and 79.8% (DeepSeek-R1), respectively.

At the heart of the model lies a reinforcement learning mechanism that incentivizes problem-solving. This innovative strategy not only cuts down on training expenses but also simplifies the overall training process. The team has indicated that their future endeavors will center on refining the reward system to further bolster the model's reasoning reliability.
