Abstract

Given the growing adoption of Large Language Models (LLMs), mitigating the environmental impacts of AI-user interactions becomes a critical concern. We study whether real-time feedback on resource consumption changes LLM usage patterns and reduces CO2 emissions in an educational setting. Our use case draws on a between-subject experimental design and rich AI-user interaction data collected on an AI learning platform. Our results show lower emissions and total tokens per prompt for the real-time feedback group, indicating that informational feedback can influence selected measures of students’ LLM usage.<br>
