An open secret about artificial intelligence systems like ChatGPT is that they all have an unsettling quirk: Not even the researchers who build them fully understand how they work. These large language models, or LLMs, are special computer programs based on mathematical structures called neural networks. Although neural networks are now ubiquitous in scientific research and daily life, and researchers have studied them for over half a century, their inner workings remain mysterious. How is that possible?
