We lack detailed information about OpenAI's inference infrastructure, but Sam Altman estimated that a single prompt costs around $0.09, with energy consumption being a significant part of this cost. Each AI request uses about 0.3 kWh, equivalent to charging a smartphone 60 times. For ChatGPT, 28,936 Nvidia A100 GPUs consume substantial energy, resulting in a carbon footprint of 0.3 gCO2e per 1,000 tokens. DALL-E 3's carbon footprint is estimated at 4 gCO2e per image. A typical ChatGPT query generating 1,000 tokens and two images releases approximately 8.3 gCO2e, comparable to charging a smartphone or driving 30 meters in a gas-powered car.
