EF 3.1 single score: 18.89 µPt
About 14 minutes of an average person's yearly footprint in these categories. 9 of 16 categories, 72% of the EF weight. Fossil resource use counts the fuel burnt for dutch electricity, not its supply chain; water scarcity uses the aware factor for the netherlands (0.957).

Prompt tokens are those actually computed (fresh input plus cache writes); 304,025,849 more were read from the prompt cache and are not recomputed, and loading that cache is not modelled. The model's size is not published, so it is inferred from its price. | assumed | 1457.4160 | 390.5875 | 7626.658 |
