===== An agent is typically an autonomous entity that has the ability to act on the environment, process information, and make decisions in pursuit of some goal or set of goals. The key feature of an agent is its active role in influencing its environment based on its internal state, goals, or learning process. =====

In contrast, an entity can refer to anything in the system, whether it is active or passive. Entities are simply objects or beings that exist within the system and have certain properties, but they might not necessarily engage in the system's dynamics in an autonomous or goal-directed manner. They could be inanimate or passive components of a larger system.
