What is AGI (Artificial General Intelligence)?

AGI stands for Artificial General Intelligence, which means an AI system with general, human-level (or beyond) ability to learn, reason, and apply knowledge across a wide range of tasks and domains. AGI systems conceivably could handle novel situations, not just perform well on a single, narrow task. The term is controversial in several ways, including that different people mean different things by "human-level intelligence," and there's no universally accepted test, so claims are hard to verify. There are also safety and ethical concerns debated by AI experts.
