What Are AI Agents (and How Are They Different from LLMs)?
Most popular AI tools today are powered by large language models. They generate text, answer questions, and follow instructions. But they're reactive by design. They wait for prompts and don't independently decide what needs to be done.
AI agents go a step further. They combine language understanding with decision-making, planning, and action. They don't just respond, they initiate, adapt, and act. They can identify goals, determine the steps required, select the right tools, and execute.
True AI agents are:
-
Autonomous: They proactively identify tasks and drive them toward completion
-
Goal-oriented: They’re assigned an outcome, not a script
-
Tool-capable: They know how to interact with APIs, systems, and codebases
-
Context-aware: They remember what they’ve done and why
-
Self-improving: They adapt based on outcomes and feedback
Think of the difference as this: an LLM answers questions. An agent solves problems.
