Report of the 11th session of the IWG on AI held on 2 September 2026 online. The session discussed the status of the draft reference document, with the USA formally objecting to the refresh plan (AI-11-03, AI-10-04) and insisting that AI-09-06/Rev.3 presented to WP.29 was the only valid baseline document. The co-chairs and majority of experts, including the UK, Germany, France, Canada, the Netherlands, EU Commission, OICA/CLEPA, and SAE, supported using AI-11-03 as the baseline. The group decided to establish two small drafting groups to address green text in sections 2 and 4, with changes submitted through change request forms for review during plenary sessions.
