What Is an Agent Loop? How AI Agents Reason, Act, and Iterate

An agent loop is the iterative cycle enabling AI models to reason, act, observe results, and adapt—the foundation of effective agentic systems. Unlike single responses, loops handle multi-step workflows with real recovery, but require explicit guardrails (stopping conditions, verification, human approvals) to prevent mistakes at scale.
