GenAI Summit 5 takes over the Stavros Niarchos Foundation Cultural Center in Athens under the theme Agents at Work. Organisers expect more than 5,000 attendees and 200 speakers from 1,200 companies, moving the conversation past pilots into deployment, ROI and governance. Past editions have hosted Mistral AI co founder Arthur Mensch and Greek Prime Minister Kyriakos Mitsotakis. Three stages run at once, including the Stavros Niarchos Hall and an alternative stage for hands on sessions.
