OneDayAgent: A Harness for Long-Horizon Autonomous Agents

zjunlp · hf · 2026-08-06

To address issues like goal drift, state loss, and context overflow when LLM agents handle long-horizon, cross-environment tasks, researchers introduced OneDayAgent.

This framework turns open-ended requests into a managed execution process: decomposing tasks into bounded subtasks, maintaining execution memory under context pressure, and verifying and repairing final deliverables. On the AgentIF-OneDay test set with 104 tasks, paired with the GLM-5.2 backend, OneDayAgent achieved a new state-of-the-art score of 0.821. Furthermore, the harness generalizes across five backend LLMs from three model families without requiring tuning.
