- November 9 paper is public. This review checked the abstract; runnable artifact availability was not established.
Evaluation horizon changes the picture
The authors describe six models, 150 runs and 24-hour budgets. Many runs improved during the second half, so an early score can give an incomplete picture.
More time does not remove reliability problems
The reported traces include task violations, unreliable tests and premature completion. Better optimization results should be checked alongside whether the agent respected the task and validated its changes.

Infrathon evaluates whether agents keep improving AI infrastructure when given long working budgets. Its results suggest that short tests can miss later gains and change the apparent model ranking.
