500 tons of CO2 is... surprisingly little? Like, rounding error little.
I mean, one human exhales ~400 kg of CO2 per year (according to this). Training GPT-3 produced as much CO2 as 1250 people breathing for a year.
That seems so little because it doesn't account for the data-centers construction cost, hardware production cost, etc... 1 model costing as much as 1250 people breathing for a year is enormous to me.
I don't know why people downvoted you. It is surprisingly little! I checked the 500 tons number thinking it could be a typo or a mistake but I found the same.
