@Spirit@cybernetic.monster @gvwilson@mastodon.social It takes 53 kJ to heat 6 oz of water from 25°C to 100°C. There's no credible public information on how much energy an average ChatGPT query costs, but the high-end estimate is 3 Wh = 10.8 kJ. (Of course, OpenAI could just tell us, if they cared.) If 3 Wh is right, Spirit's claim exaggerates reality by a factor of 50. It might be more like 0.3 Wh, which would mean the claim is off by a factor of 500.
