Introducing a New AI Metric for Sustainability
Summary
GreenPT introduces a sustainability metric for AI, measuring energy efficiency as mWh per 100 output tokens to provide transparency and support carbon impact reporting.
Key quotes
mWh per 100 tokens (sampled at 1-second intervals)
If the field is to scale responsibly, we need a metric that makes efficiency a product decision, not an afterthought.
The post details a proposed framework for measuring AI energy consumption by normalizing energy use (mWh) against output tokens generated. It aims to align with Software Carbon Intensity (SCI) reporting and ISO standards, currently focusing on GPU-level transparency.
