Energy figures based on third-party estimates (earth911.com, devera.ai, MIT Technology Review 2025). Token-based Wh estimates: ~0.5–8 Wh/1K tokens depending on model and infrastructure. Anthropic and most AI providers do not publish official per-request figures. CO₂ intensity factors from IEA 2024. GPU wattage reflects typical values under full load. All figures are indicative.
