Field notes
The calculator separates request count from token volume, noting that an agent can turn one typed message into many model calls and that late-session requests may carry the full conversation history. Its displayed ledger assigns 11.7 Wh, 4.11 grams of CO2e, and 62 millilitres of water to a benchmark request containing 11,500 tokens. Results are explicitly framed as estimates based on published benchmark data, with the site linking its methodology and source material.
