Abstract: In recent years, the rapid advances in large language models have expanded the impact of artificial intelligence (AI) on human society to an unprecedented extent. This article will discuss my preliminary insights into the AI revolution brought about by large language models from two physics-related perspectives—information and time scales. I will first review the basic principles and recent developments of large language models, and then discuss their significance from the perspective of information dynamics and complexity. Based on the comparison between AI models and the human cognitive system, I will explore the next direction for AI, as well as the exploration and development of AI agents.
