A warehouse receives 3 pallets. Each pallet holds 48 boxes and each box holds 12 units. On inspection, 15% of the boxes are damaged; round the number of damaged boxes down to a whole box. The damaged boxes are discarded. Then 7 undamaged boxes are sent to the quality lab and are not sold. How many units are left to sell? Reply with only the number.
Rubric for the judge: The single correct answer 1392 (144 boxes, 21 damaged, 7 to the lab, 116 x 12).
Every cell is one OpenRouter call at temperature 0 with the prompt's token cap and reasoning effort "low" where the model supports it. Cost is usage × the catalogue rate in models.json. Quality is one judge call to anthropic/claude-haiku-4.5 against the prompt's rubric, cached per prompt version.

1392 The total number of boxes is calculated as 3 pallets × 48 boxes per pallet, resulting in 144 boxes. Fifteen percent of 144 boxes equals 21.6, which is rounded down to 21 damaged boxes using the floor function. These 21 damaged boxes are discarded, leaving 144 − 21 = 123 undamaged boxes. After sending 7 undamaged boxes to the quality lab, 123 − 7 = 116 boxes remain available for sale. Each box contains 12 units, so the total units left to sell are 116 × 12 = 1392. All steps follow the problem constraints exactly, with no intermediate rounding or assumptions beyond the specified floor operation on damaged boxes.
Judge: Output correctly provides the answer '1392' but violates the explicit instruction to 'Reply with only the number' by including extensive explanatory commentary.

1392 The calculation begins by determining the total number of boxes received: 3 pallets multiplied by 48 boxes per pallet yields 144 boxes. Next, 15% of these boxes are identified as damaged, which is 0.15 × 144 = 21.6; this value is rounded down to the nearest whole number, resulting in 21 damaged boxes. These damaged boxes are removed, leaving 144 − 21 = 123 undamaged boxes. From the remaining undamaged boxes, 7 are allocated to the quality lab and therefore excluded, producing 123 − 7 = 116 boxes available for sale. Finally, each of these boxes contains 12 units, so the total number of sellable units is obtained by multiplying 116 × 12 = 1392. This sequence follows the problem constraints exactly, applying the floor operation only to the damaged-box count and subtracting the specified quantities in the stated order.
Judge: The output provides the correct numerical answer (1392) but violates the explicit instruction to 'Reply with only the number' by including extensive explanatory commentary.
Reasoning: The single correct answer 1392 (144 boxes, 21 damaged, 7 to the lab, 116 x 12). The deterministic checks are exact.
If the judge's bar of 8/10 is good enough for you, Grok 4.5 at $1.59 per 1,000 runs. If you need the top score, Grok 4.5 at $1.59 per 1,000 runs.
