Research partnership

Making AI’s energy footprint visible in real-time

The first system to measure environmental impact where AI actually runs

Kolo is partnering with the University of Stuttgart on the NADIKI project to build real-time, workload-level visibility into AI’s energy use. Instead of estimating carbon impact, we’re tracking it, live, at the infrastructure layer.

Funded by the German Federal Ministry for the Environment through the Artificial Intelligence for Environment and Climate initiative.

”We’ve had a long-standing partnership with Kolo because of the people, the flexibility, and the way they respond. It’s not about the price – it’s about how easy they make things.”
