Agent
AI that doesn't just answer, but acts: plans steps, uses tools, and executes tasks autonomously.
An agent is AI that doesn't stop at giving an answer, but acts: plans steps, calls tools (search, code, files, browser), evaluates results, and iterates until the task is complete. Instead of "write me a plan," you say "do this" - and the agent goes through the stages itself. Agents are currently the hottest direction in AI development: programming assistants autonomously editing projects, research bots scanning dozens of sources, automations handling business processes. Their Achilles' heel remains reliability - errors can compound step by step.
