CO₂ Emissions and Model Performance: Insights from the Open LLM Leaderboard

Hugging Face published an analysis correlating CO₂ emissions with model performance across submissions to the Open LLM Leaderboard. The study examines the environmental cost of open-weight model development and inference, exploring efficiency trade-offs between model size, benchmark scores, and carbon footprint. The analysis provides empirical data to help researchers and practitioners evaluate sustainability alongside capability metrics.
