An AI agent is a software entity designed to perceive its environment, process information, and take actions autonomously to achieve specific goals. These agents can operate in various domains, including robotics, virtual assistants, and gaming. They utilize techniques such as machine learning, natural language processing, and decision-making algorithms to interact effectively with users and their surroundings. AI agents can learn from experiences, adapt to changing conditions, and improve their performance over time. With applications ranging from customer service chatbots to self-driving cars, AI agents are revolutionizing how we interact with technology, making processes more efficient and intuitive.
