Not each on their own. Together, one public AI facility.

Gem is not a standalone technology or an individual virtual assistant, but a collective facility for municipalities.

Together we develop a virtual assistant and apply AI in municipal services. By working together, municipalities share knowledge, costs, experience and development capacity.

Working together means taking responsibility together

Not consecutive steps, but four things that happen alongside each other all the time.

Building together

One collective movement of municipalities building better digital services together.

Municipalities contribute practical questions, knowledge and priorities. Together we decide what Gem should be able to do and which developments add value. Not each municipality separately: developing together is better and cheaper.

Answers that are correct

Contact with a virtual assistant is only valuable if residents can trust it.

Municipalities work together on correct, up-to-date and understandable answers, including with generative AI. The focus is not on the technology, but on the quality of the service.

AI under municipal control

Gem is not a supplier's virtual assistant, but a government facility.

No dependence on a single supplier, but joint steering on values, risks and development — with sovereign technology, together with partners such as VNG, BZK and ICTU.

Learning and scaling up

What one municipality learns becomes valuable for all municipalities.

Every experience, improvement and investment benefits the entire municipal community. This makes innovation faster, safer and more widely applicable.

What your municipality contributes, everyone gets back

Gem is not a product you simply purchase. It is a shared facility that municipalities contribute to and benefit from together.

Your municipality contributes

  • practical questions, knowledge and priorities
  • municipal knowledge and content
  • experience from day-to-day service delivery
  • expertise in privacy, security, accessibility and transparency
  • improvements and investments

The collaboration gives back

  • shared technology, content and functionality
  • reusable components
  • joint quality agreements
  • documentation and implementation experience
  • knowledge and improvements from other municipalities
  • shared costs and development capacity

This creates a future-proof solution available to the shared municipal practice.

Public control, under the bonnet too

The technology matters. But public values determine how we use it.

How do municipalities steer together?

Participating municipalities help develop the technology, the quality of answers, governance, implementation and preconditions such as privacy, security, accessibility and transparency.

Municipalities contribute practical questions, knowledge and priorities. Together we decide what Gem should be able to do and which developments add value. Partners such as VNG, BZK, ICTU and knowledge partners support the collaboration.

Which meeting suits which role?

Even though the virtual municipal assistant runs on technology, the effort is and remains human work. Your colleagues join the meetings that suit their role on a structural basis. Municipalities collaborate at three levels:

Content development (content team)

  • We share insights on setting up the municipal website better for conversational AI.
  • We share insights on our residents' questions and on how we can improve the technology, so that answer quality increases.

New wishes and questions (portfolio meeting)

  • We share the considerations for deploying open-source technology, with a preference for sovereign solutions.
  • Together we contribute to the roadmap for the further development of the assistant.

Joint policy agreements and documentation

  • We share available expertise in areas such as information security, privacy, sustainability, ethics and legal matters.
  • We record our choices in shared documentation and papers that are relevant to all municipalities, such as the vision on virtual assistance in public service delivery.
How do we safeguard the quality of answers?

Contact with an AI-powered virtual assistant is only valuable if residents can trust it. Within Gem, municipalities work together on correct, up-to-date and understandable answers, including with generative AI.

The focus is not on the technology, but on the quality of the service. All municipalities contribute relevant knowledge: reliable support based on municipal knowledge, experience and quality agreements.

What do LLM and RAG mean?

An LLM (large language model) is the language model that processes language and formulates answers. RAG (retrieval-augmented generation) lets the model base its answers on selected information sources, rather than on what the model itself "thinks it knows".

Municipalities jointly keep a grip on the choices around LLM and RAG, steer on values and jointly manage the risks and further development with sovereign technology.

How do we handle public values and risks?

Participating municipalities help develop preconditions such as privacy, security, accessibility and transparency. Together they commit to sharing available expertise in areas such as information security, privacy, sustainability, ethics and legal matters.

The joint choices are recorded in shared documentation and papers that are relevant to all municipalities, such as the vision on virtual assistance in public service delivery.

What do open source and Common Ground mean?

Gem is fully open source under the EUPL licence and built according to the Common Ground principles. That makes the technology reusable and transparent: no vendor lock-in, no licence fees.

In cooperation with partners such as VNG, BZK, ICTU and knowledge partners, municipalities build an open, reusable and scalable facility.

What Gem stands for

  • Open source (EUPL licence)
  • For and by municipalities
  • Municipal control
  • Reusable and scalable

What can your municipality add?

Together we discover what your municipality can add to the Gem collaboration. Every municipality brings knowledge, experience and practical questions.
