As AI systems grow more powerful and politically charged, the need for effective governance has never been greater. The Athens Roundtable exists for such moments: a focused, credible forum to tackle the hardest governance challenges directly and without pretense.
In 2025, we invited participants to confront the toughest questions: AI’s technical future, the policy landscape, and geopolitical sensitivities. How do we define and prevent unacceptable risks? What safeguards are needed to detect and respond to AI incidents? How can we bridge divides to build lasting accountability and protect future generations?
The theme of this year’s edition is facing the stakes of AI together: from shared concerns to joint action.
Our goals are to:
Stress-test global AI governance by examining technical, policy, and geopolitical challenges—identifying what works, what doesn’t, and what comes next.
Advance international coordination through candid, closed-door dialogue on two priorities:
Unacceptable AI risks: building shared understanding and exploring diplomatic pathways for oversight and verification.
Incident prevention and preparedness: strengthening institutional capabilities and coordination before crises escalate.
