arXiv:2606.26918v1 Announce Type: new Abstract: Large language models can serve as capable long-horizon agents, but their out-of-distribution (OOD) generalization remains weak. We identify a key source of this failure as task insensitivity: when faced with similar but distinct tasks, models might apply patterns learned during training and fail to solve the task at hand. We show that models often continue with actions aligned with the original task even when the instruction is semantically corrupted and cannot be directly answered. We further find that, when we replace the task description in a
The rapid deployment and increasing complexity of AI agents necessitate understanding their limitations, especially regarding OOD generalization, to prevent failures in critical applications.
Improving OOD generalization in language agents is crucial for their reliability and broader adoption, impacting the efficiency and trustworthiness of automated systems in various sectors.
This research identifies a specific failure mode in language agents ('task insensitivity'), providing a clearer pathway for developing more robust and adaptable AI, shifting focus towards instruction fidelity.

Immediate research efforts will focus on mitigating task insensitivity and improving instruction-following capabilities in large language models.
More reliable AI agents will accelerate the automation of complex workflows, leading to increased productivity and potentially displacing certain white-collar jobs.
Widespread deployment of highly robust AI agents could fundamentally reshape organizational structures and the nature of work, pushing human roles towards oversight and creative problem-solving outside of established patterns.
