## Summary

Researchers introduced AOS-Bench, a new benchmark for evaluating AI agents as persistent workload managers. Unlike existing tests, it measures how agents handle overlapping tasks—such as builds, data processing, and bug fixes—under shared CPU and memory constraints. The benchmark shows that success rates vary widely: on heavy workloads, systems lose 13 to 23 points, while on medium workloads, two systems with similar isolated performance deliver 54% and 68% of the same tasks. The study highlights that task intake and concurrency policies significantly impact efficiency, with serial dispatch leaving 73% of heavy tasks unclaimed. Even fixed concurrency policies perform nearly as well as dynamic management, keeping CPU use under 30% during task waits.

## Key points

- AOS-Bench evaluates AI agents managing overlapping tasks under CPU/memory limits, unlike isolated benchmarks
- Systems lose 13–23 points on heavy workloads and show 11–26 point gaps in stream success rates
- Task intake policies matter most: serial dispatch leaves 73% of heavy tasks unclaimed, but fixed concurrency nearly matches best policies

## Why it matters

AOS-Bench reveals a critical gap in AI agent benchmarks: real-world workloads require dynamic task prioritization, not just isolated task success. This could reshape how agents are designed for production use, where multiple jobs compete for resources.
