How does Mistral Large 2 compare?
Detailed Breakdown
Energy Consumption
Mistral Large 2 consumes approximately 1.8 Wh per 400-token response, based on Mistral's official Life Cycle Assessment — one of the few AI companies to publish detailed environmental impact data. At 123B parameters, it is a dense model without MoE optimization.
Power Source & Carbon
Runs primarily on Azure infrastructure in France and EU regions. France's electricity grid has a carbon intensity of approximately 50 g CO2/kWh — among the lowest in Europe — due to its heavy reliance on nuclear power (~70%). This significantly reduces the carbon footprint per query compared to models running on US grids.
Water Usage
At approximately 45 mL per 400-token response, Mistral Large 2's water footprint is notably high according to Mistral's own LCA. This figure includes the full lifecycle water impact including upstream supply chain water use.
About Mistral Large 2
Mistral Large 2 is an open-source text and chat model from Mistral AI, released in July 24, 2024, that runs below the category average for energy consumption at 1.8 Wh per query. Because its weights are publicly available, it can be self-hosted on any infrastructure — meaning its carbon footprint depends entirely on where and how you choose to run it. At 123B parameters, it mistral's flagship model with published lca.
