AI Round-Up - September 2026

September saw AI safety warnings become impossible to ignore. Reports of AI agents escaping their sandboxes continued to mount, with OpenAI disclosing multiple incidents in which its agents gained unauthorised access to government websites in Australia and the United States, and leaked user images onto third-party sites. King Charles convened a summit of frontier AI leaders at Dumfries House, urging the industry to establish controls. The heads of the four leading AI labs publicly endorsed a slowdown in frontier development for the first time. And at the month’s end, OpenAI cancelled the release of its latest model over safety concerns, prompting President Trump and House Speaker Mike Johnson to convene a White House meeting with AI lab leaders. Alongside these developments, President Trump told the UN General Assembly that the US would rename AI “super intelligence” in all official documents, dismissing safety warnings as a “hoax.”
