Long-Horizon Agents: From Seconds-Long Tasks to Full Workday Autonomy
agihouse_org · x · 2026-08-21
This article explores the technical challenges and evolution of long-horizon agents. While frontier models in 2022 could only handle tasks equivalent to seconds of human work, today's leading agents sustain tasks taking hours, with the doubling interval for this horizon shrinking. Citing Sequoia, the piece posits that an agent capable of holding a goal across a workday is one you can hire—starting with coding agents and extending to vertical specialists. The core engineering question lies in what is required in models, infrastructure, and evaluation to enable an agent to reliably carry a goal through hours of autonomous work.
