The 9th session of the Informal Working Group on AI convened 3-4 June 2026 in London. Experts adopted the agenda and reviewed the consolidated draft reference document AI-09-06, which was substantially revised through two iterations (AI-09-06/Rev.1 and AI-09-06/Rev.2) before final submission to WP.29 as AI-09-06/Rev.3. Key modifications included limiting use cases in section 3 to driving functions, removing section 6 and the “other use cases” section, and incorporating lifecycle risks in sections 4 and 5. The IWG received a presentation on ISO/PAS 8800/2024 AI safety standards. A 1-year mandate extension was requested to submit a formal document for the June 2027 WP.29 session.
