Is it true that a typical ChatGPT query consumes about half a liter of water through data center cooling?

Partly. One reference work reports a 2023 UC Riverside estimate that 5 to 50 ChatGPT prompts need about 0.5 liters of water for server cooling, while a 2026 bottom-up estimate puts a single query at roughly 4.3 milliliters of water. The two placed sources give figures that differ by orders of magnitude, so the evidence does not settle the claim.
