What does ChatGPT do?
Frontier generalist with deep reasoning.
The short answer
ChatGPT is built by OpenAI and is positioned for code, writing, analysis, research and agents. Our readings score it strongest on multi-step reasoning and code generation.
Its weakest measured axis is response speed (72/100), 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 61/100. The energy mix is mixed, and disclosure covers some but not all serving regions.
Water and local impact reads 55/100. Some sites use evaporative cooling in regions with moderate water stress.
Speed and efficiency also matter here: a 72/100 speed reading means fewer compute-seconds per answer for routine work.
