OpenAI CEO Sam Altman revealed that each ChatGPT query uses about 0.34 watt-hours of energy and about 0.000085 gallons of water, equivalent to one-fifteenth of a teaspoon, refuting higher estimates by analysts. As AI models grow, aggregate water and energy consumption might pose a concern despite low per-query usage, as AI data centers get millions of queries daily. OpenAI releasing these figures is seen as an effort to enhance transparency about its AI infrastructure's environmental impact.
