AI agents are intelligent software programs that autonomously perform tasks, make decisions, and interact with users or systems using AI techniques such as machine learning (ML), natural language processing (NLP), and reinforcement learning.
They operate in an environment, perceive changes through sensors, and act upon them to achieve goals. Based on their autonomy, they can be reactive agents (which respond to stimuli) or deliberative agents (which plan actions before execution). More advanced AI agents use deep learning models for decision-making, such as OpenAI’s GPT-based conversational agents.
A practical example is an AI-powered chatbot in customer service, which understands user queries and provides responses. AI agents are widely used in automation, robotics, recommendation systems, and virtual assistants like Siri and Alexa.
