Bottles Saved for ChatGPT

Turn the estimated water used by ChatGPT into a small, visible counter with four ways to understand the number. Bottles Saved for ChatGPT counts new assistant responses and generated images after installation. Click the counter to switch among: - Bottles saved (the default): 500 mL bottle equivalents. - Raw water used: the estimated total in milliliters. - Golf-course day: your estimated total as a percentage of one average day for the median 2024 U.S. 18-hole facility. - Corn-field day: your estimated total as a percentage of a representative peak-use day for a square 160-acre corn field. The selected view is remembered locally. The panel also shows text-response and generated-image counts, current assumptions, primary sources, and a reset control. Golf and corn benchmark definitions are available directly from the info tooltip, including the chosen field acreage. Current defaults: - Text response: 0.32 mL, based on OpenAI’s June 2025 statement that an average ChatGPT query uses about 0.000085 gallons of water. - Generated image: 0.08–3.9 mL, a provisional proxy derived from a June 2025 energy study of 17 open image models and OpenAI’s reported average energy-to-water ratio. The extension is honest about uncertainty. OpenAI has not published detailed methodology for its average-query figure or a direct image-specific water measurement. Actual use varies by model, workload, data-center location, weather, and accounting boundary. You can edit the assumptions inside the counter. Daily comparison benchmarks: - Golf: the Golf Course Superintendents Association of America reports a median of 75.9 irrigated acres and 83.9 acre-feet per year for U.S. 18-hole facilities in 2024. The extension averages that annual figure over 365 days (about 74,901 gallons/day). Actual irrigation is seasonal and regional. - Corn: Iowa State University Extension models an average peak crop-water demand of 0.2 inches/day near V18 for central-Iowa corn. The extension applies that to a square 160-acre quarter-section (about 868,936 gallons/day). This is an illustrative evapotranspiration benchmark, not a universal irrigation withdrawal. Privacy first: - Runs entirely in your browser. - Makes no network requests. - Stores no prompts, chat text, image contents, or browsing history. - Stores only local counts, the selected display mode, estimate settings, and opaque message keys used to prevent double-counting. “Bottles saved” is a playful water-volume equivalent. It does not mean literal plastic bottles were produced or avoided. This is an unofficial extension and is not affiliated with or endorsed by OpenAI.
