Google internally measured 0.24 Wh and 0.03 gCO2e per median prompt.

The Short Version #

The figures accurately reproduce Google’s reported median of 0.24 Wh and approximately 0.03 gCO2e per Gemini prompt, but they were derived from Google’s internal instrumentation. No independent third party has verified or reproduced those measurements. Because the claim materially misstates the provenance and evidentiary status of otherwise accurate numbers, it is largely unsupported as worded.
