On 4–5 February, Spain hosted the third REAIM Summit—a multistakeholder gathering dedicated to international dialogue on the responsible development and use of AI in the military domain. SIPRI’s Governance of AI programme was on the ground, contributing to the conversations, with two of its members sharing insights from their recent work. Dr Vincent Boulanin joined the panel on the ‘International Security Implications of Agentic AI and its Impact on the Military Domain’.
