AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
Why it matters
Explains where a general-purpose classifier model beats both frontier LLMs (on speed and cost) and task-specific classifiers (on generality). This helps engineers decide which to use for high-volume classification steps in AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → pipelines.
