What is Long-Horizon Agents?
Overview
Long-horizon agents are AI systems designed to complete tasks that require many steps, extended execution time, persistent state, and repeated tool use. They matter because real software, research, and operational workflows demand more than a single response: agents must preserve context, detect errors, recover, and remain aligned with the original goal.
Why it matters
Long-horizon reliability is a key barrier between impressive agent demonstrations and dependable automation in production workflows.
