Open Source and Models to drive European Sovereignty
This year, we are focusing on the theme of Open source software and open models to strengthen European sovereignty. To gain technological independence, citizens and organisations in the European Union want to pursue a sustainable and responsible digital strategy based on secure and resilient infrastructures, operated and controlled in Europe. Please submit your proposals in English on this theme or on one of the topics suggested in the call for presentations form.
Be part of the action! Please submit your proposals, in the main theme or any other CFP topics, in English. The CFP deadline is February 14, 2026.
