Our Own AI Server: Artificial Intelligence Made in Steinmühle

Thanks to the support of our booster club, chaired by Jasmine Weidenbach, and a wealth of in-house expertise, Steinmühle has had something for several months now that most schools in Germany do not yet have: its own AI server—and with it, true digital sovereignty.

Behind the unassuming server case lies remarkable computing power: Two high-performance NVIDIA graphics cards power state-of-the-art open-source language models—including GPT-OSS-120b, Gemma 3, and Mistral 7b. The OpenWebUI interface makes them intuitive for teachers and students to use. The hardware is deliberately designed to be scalable, ensuring that growing usage will not cause bottlenecks. The server and its features were presented to the faculty at Steinmühle during the school’s internal teacher training program (SchiLF).

 

The server operates in a completely climate-neutral manner

Steinmühle is particularly proud of its sustainable operations: The server runs entirely climate-neutrally—powered by hydropower and the school’s own photovoltaic system. — So, for us, AI and sustainability are by no means mutually exclusive.

But what exactly can the server do? We’re currently testing several exciting applications: a parent assistant with information about Steinmühle, a resource assistant for the religion department, exam assistants for teachers, and other experimental projects. Everything runs on our own infrastructure—no data leaves the school, and full GDPR compliance is guaranteed.

 

The Interplay Between Education and Technology

Recent developments also show that we’re on the right track with this approach: We’ve just submitted our entry to a prestigious 2026 competition—with our data-sovereign server at the heart of the concept. We’re very excited to see what happens!

Steinmühle would like to thank the school administration and management for their vision of a school that responsibly combines education and technology. We are proud of our experts, who developed our project and are keeping an eye on its future development.
