The figure is 1/20th to 1/4th of earlier estimates, which Microsoft says failed to account for batch processing and production GPU utilization rates.","whyItMatters":"The revised figures challenge widely cited claims that a single AI query uses several watt-hours, with implications for data center planning and public perception of AI energy costs.","webCardHtml":"\u003cp\u003eMicrosoft\u0026#39;s research team based the estimate on a model with over 200 billion parameters running on a server with eight NVIDIA H100 GPUs. They combined metrics including tokens processed per second, per-server power consumption, and facility-level Power Usage Effectiveness (PUE). For a median query of about 300 tokens, median power consumption was 0.31 Wh, with the central 50% of the range falling between 0.16 and 0.60 Wh. Water consumption for cooling was estimated at 0 to 0.067 mL per query.\u003c/p\u003e\u003cp\u003eMicrosoft argues that earlier estimates-some suggesting a ChatGPT query uses roughly 10 times the power of a Google search-overstated consumption by 4 to 20 times because they did not reflect batch processing or efficient GPU operation in high-user environments. However, the company notes that queries requiring multi-step reasoning or long code generation, with a median response of 5000 tokens, consume about 3.91 Wh, roughly 13 times a typical query.\u003c/p\u003e","blueskyPost":"Microsoft's own data cuts AI query energy estimates to 1/20th of prior figures.
