If the prices are cost, and the cost is electricity not hardware, and the electricity is $0.05/kWh, every 1000 tokens (750 words) of ChatGPT is $0.002 = 1/25 kWh = 40 Wh.

Average human reading speed varies by language but one average over many languages is 184±29 wpm, so those 750 words will take you about 4 minutes (4.07) to read.

If you're an American, your average electric consumption in that time is 1,387 W * 4.07 minutes ≈ 94 Wh.

But the human still exists.

(You compute your carbon footprint per minute by adding up all the things you do in a large period of time and dividing by the duration. This chatgpt footprint should be added to the numerator, it doesn't replace the whole thing)

But the human requires oxygen and water and lots of climate control.

If AI is useful as we think it is, then having huge compute farms in space would be the best long term goal.

Sure, I'm just saying ChatGPT is low energy even compared to the opportunity cost of reading its output.
