“The environmental impact of questioning trained (large-language models) is strongly determined by their reasoning approach, with explicit reasoning processes significantly driving up energy consumption and carbon emissions,” first author Maximilian Dauner, a researcher at Hochschule Munchen University of Applied Sciences, Germany,…
