What does Copilot do?

Office-embedded assistant running on OpenAI frontier models.

The short answer

Copilot is built by Microsoft and is positioned for chat, writing and analysis. Our readings score it strongest on code generation and multi-step reasoning.

Its weakest measured axis is response speed (78/100), so plan around that when the work depends on it. Access is paid, and the weights are closed, so you can only reach it through the vendor's own service.

Energy, carbon and water

Carbon footprint reads 55/100. The energy mix is mixed, and disclosure covers some but not all serving regions.

Water and local impact reads 48/100. Some sites use evaporative cooling in regions with moderate water stress.

Speed and efficiency also matter here: a 78/100 speed reading means fewer compute-seconds per answer for routine work.
