Autonomous agent
An autonomous agent is an AI system that pursues a goal over multiple steps with minimal human intervention, deciding what actions to take, executing them via tools, observing results, and iterating until the goal is achieved or judged unreachable. Autonomy lives on a spectrum: from one-shot completion to fully open-ended multi-day operation.
The autonomy axis is the defining 2024-2026 progression in AI applications. At one end: a coding assistant that proposes a diff for human review (low autonomy, high oversight). At the other: an agent given a vague brief that researches, drafts, tests, and iterates over hours (high autonomy, low oversight). The right point on the spectrum is task-dependent: high-stakes work (financial transactions, code that ships to production) typically warrants lower autonomy and tighter oversight; exploratory or low-stakes work can tolerate more. Production deployment patterns commonly include async-with-checkpoint (the agent runs autonomously but pauses at defined checkpoints for human review).
