Autonomous Agent

An AI agent that completes multi-step tasks from start to finish without requiring human intervention at each step. Autonomous agents plan their approach, execute using tools and APIs, handle errors, and deliver results independently. The degree of autonomy exists on a spectrum—from copilots (suggest, human executes) to semi-autonomous (execute routine steps, ask for approval on high-stakes ones) to fully autonomous (end-to-end without human input). Most production agents operate in the semi-autonomous range.
