AI Agent
An AI system that does not just answer — it acts: planning multi-step tasks, using tools (search, code, APIs), checking its results, and iterating until the goal is reached. Where a chatbot writes you a prompt, an agent could generate the image, evaluate it, refine the prompt, and upscale the winner autonomously. Agents power automation workflows: 'create 20 on-brand social posts from this article' becomes one instruction instead of forty manual steps. The practical skill is writing clear goals and constraints — agents amplify good instructions and vague ones equally.
