Interval s
interval_s
Average interval between lift arrivals
Scores if within ±3% of the reference value.
Calculates the average waiting interval between lift arrivals by dividing round-trip time by the number of lifts. The template also reports the number of lift arrivals available in a five-minute assessment period.
with-tool: The model is given an executable Python calculator script.
Standards
One template produces many comparable benchmark tasks while keeping the scoring contract fixed.
01
The reusable contract shown on this page.
02
An archetype and site context are sampled.
03
Inputs may be hidden at harder tiers.
04
The model responds with the declared outputs.
Inputs the model receives, and the outputs it is scored on.
2 inputs
Included directly in every task prompt.
Round trip time
round_trip_time_s
Lift round-trip time
Visible in easier tasks and withheld in one or more harder tiers.
Lift count
lift_count
Number of lifts in the group
Hidden at hard difficulty.
2 outputs
interval_s
Average interval between lift arrivals
Scores if within ±3% of the reference value.
arrivals_per_5min
Lift arrivals in a five-minute period
Scores if within ±3% of the reference value.
Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.
All inputs given
Small lift group with all values visible
All inputs given
Small or large lift group
Some inputs hidden
Lift count hidden in group context
Hidden inputs
Prompt replacement text
Use the lift group size implied by {{ archetype.description }}.
Lift count restricted to: 6
