AI agents are revolutionizing automation in technical teams by transitioning from traditional rule-based systems to dynamic, intelligent frameworks capable of real-time decision-making. Unlike static systems dependent on predefined triggers, AI agents utilize large language models (LLMs) for processing complex data, understanding context, and handling unpredictable scenarios. These agents can autonomously perform tasks, make decisions, and interact with environments, making them valuable for automating and outsourcing complex cognitive tasks. The article explores various types of AI agents, such as simple reflex agents, model-based reflex agents, goal-based agents, utility-based agents, and learning agents, each with unique capabilities and applications. It highlights practical examples of AI agents in action, facilitated by platforms like n8n, which allow for the easy building, customization, and scaling of AI-driven workflows. Additionally, it distinguishes between AI agents and other AI tools like chatbots, LLMs, and virtual assistants, emphasizing the autonomous action capability that defines true AI agents.
