A new paper proposes metacognition as a solution to address hallucinations in large language models. The authors argue that current models primarily improve factual accuracy by increasing knowledge rather than by developing an awareness of their knowledge boundaries. They suggest that instead of simply answering or abstaining, models should be trained to express uncertainty, which aligns with their internal confidence levels. This metacognitive ability is presented as crucial for making LLMs both trustworthy and capable, particularly in complex applications and agentic systems. AI
