How to read these numbers

Score is the mean verifier score over the task set, with partial credit. Time is the mean time per task, from when the agent receives the instruction until it finishes; setup and grading are not counted. Cost is the model API cost per task. A dash means usage was not recorded.

Every configuration ran on the same tasks within its benchmark.
