> I'd still love to see a report that accurately captures training cost. Today's report[1] notably excludes training cost.

From 2022, so possibly out of date: "ML training and inference are only 10%–15% of Google’s total energy use for each of the last three years, each year split ⅗ for inference and ⅖ for training." That's probably close enough to estimate 50/50, or the full energy cost to deliver an AI result is double the inference energy.

It still kills me, every time, that the title embedded in the metadata of that original PDF is "Revamped Happy CO2e Paper".

My gosh you're right! The paper in question is https://arxiv.org/pdf/2204.05149, "The Carbon Footprint of Machine Learning Training Will Plateau, Then Shrink"
