EF 3.1 single score: 4.05 µPt
About 5 minutes of an average person's yearly footprint in these categories. 4 of 16 categories, 45% of the EF weight. Fossil resource use is estimated from all primary energy, which overstates it; water scarcity uses the aware world average (1.0); the dutch factor is not loaded.

Prompt tokens are those actually computed (fresh input plus cache writes); 70,185,693 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 | 236.2593 | 63.3175 | 1236.345 |
Outcome. A Claude Code session, reported automatically when it ended. What it was for is deliberately not recorded here.
