An intelligent agent is a system or entity that operates autonomously to achieve a specific goal within a given environment. The agent gathers information from the environment through sensors and interacts with it via actuators. It possesses reasoning and planning capabilities to devise a sequence of tasks necessary to achieve the goal, and can adjust this sequence based on feedback from the environment. Over time, the agent learns from its experiences and updates its internal memory to enhance task execution. Recent breakthroughs in Large Language Models have sparked increased interest in AI agents, as they offer a new form of reasoning.
