Estimated footprint
Per single text prompt (token-scaled rows assume ~1,000 tokens).
Footprint numbers are rough public estimates that vary by 10–100× across sources and depend on data-centre efficiency and local grid mix. They are shown as a low–high band with a source and date. Don't treat them as measured fact.
