  • An autonomous entity in artificial intelligence that perceives its environment and takes actions to maximize its chances of achieving specific goals. AI agents can range from simple, rule-based systems to complex, learning-based entities capable of adapting to changing conditions. They are used in various applications, including robotics, virtual assistants, and game AI, functioning within predefined parameters to make decisions, solve problems, or interact with humans or other systems.


  • The practice of attributing human-like qualities, such as emotions, intentions, or behaviors, to artificial intelligence systems or machines. This can include designing AI with human-like appearances or interactions, making them more relatable or easier for humans to engage with. Anthropomorphism in AI is common in virtual assistants and interactive robots, enhancing user experience but also raising ethical and philosophical considerations.

Artificial General Intelligence (AGI)
