AI Agents: What They Are and Why They Matter

AI agents are the biggest trend in AI for 2025. Unlike chatbots that respond to one message at a time, AI agents can plan, execute multi-step tasks, and use tools autonomously. Here is what you need to know.

Key Takeaway: AI agents are AI systems that can take actions in the real world — browsing the web, writing code, managing files, and calling APIs. They represent the shift from AI as a conversation partner to AI as a coworker.

What Makes an AI Agent?

An AI agent has four capabilities that regular chatbots lack:

  1. Planning: Breaking complex tasks into steps
  2. Tool use: Interacting with software, APIs, and files
  3. Memory: Maintaining context across a long workflow
  4. Autonomy: Executing without human intervention at each step
