In production for more than 12 months
"MIA": the sovereign AI of the City of Annemasse & Annemasse Agglo
How a conurbation of 90,000 residents deployed its own generative AI: open source, hosted in Europe, with no dependency on any Big Tech vendor, and won the "Territoire Innovant" award in the AI category.
Key figures
340 active users
- 17,880 messages processed
- 5 thematic wikis
- 1 single GPU
The challenge
The challenge
As in every local authority, staff in Annemasse were already using consumer AI tools (ChatGPT and the like) to save time on document work, but with no framework at all, and with internal documents, some of them sensitive, being sent to servers outside the European Union. An unacceptable legal and sovereignty risk for a public administration.
The goal: give staff a tool at least as practical as the AI products on the market, but one the authority keeps full control of (data, infrastructure, budget), without runaway costs and without depending on a foreign vendor.
The solution
The solution: a sovereign AI, operated end to end
An open source model, hosted in Europe
The French model Mistral Small 3.2 (24B) served on European GPU infrastructure, with no call to a third-party AI provider: documents and questions stay inside the controlled perimeter.
Connected to the authority's documents
A full RAG pipeline (extraction, semantic search, re-ranking) and 5 thematic wikis: staff query their own working documentation and get sourced answers.
Sovereign by design
EU hosting, encrypted tunnel, daily wipe of the model's GPU server, authentication through the authority's SSO. The data stays under control.
Frugal and energy-efficient
The GPU infrastructure only runs during working hours and relies on a single GPU: sized to actual need, with no waste, for a controlled cost.
The results
The results
- 340 active users and 17,880 messages processed since the beginning of 2026: real and growing adoption.
- More than 12 months in continuous production, with GPU compute rented only in the European Union.
- "Territoire Innovant" award, AI category, presented by Les Interconnectés (June 2026, Paris).
- A reproducible model: the same foundation was then deployed across a whole département (Calvados).

Scope
Reference scope
Annemasse’s institutional publication mentions 340 users and almost 18,000 messages, and a project developed by the Ville-Agglo team. These figures do not measure concurrent generations or by themselves establish PixelRaise’s contribution. Confirm each party’s role and measurement periods before attributing commercial performance.
