I just hit my usage limit this morning, and the article shows how to get these numbers so I can answer this myself -- I'd be curious to see what other people are doing token wise day-to-day

ccusage says I had 1k input tokens, 12k output and 1.2m cache create.

I'm not sure if that is 18.3g, 138.3g or 1213 * 8.3g.

At the highest number that's 10kg or 25% of average US daily per capita emission or 1 gallon of gas.
