The White House Accord on Super Intelligence, signed September 29, 2026, commits the leaders of Google, Anthropic, Meta, OpenAI, Nvidia, and xAI to four layers of internal controls and audits focused on cybersecurity, biosecurity, and chemical threats, plus a board committee to oversee safety work at each company. The accord is not legally binding, carries no penalties for non-compliance, includes no requirement to report AI safety incidents to any government body, and places no restrictions on who may serve as auditors, meaning companies may choose their own. Trump described it as "morally binding" and "almost like a constitution". AVERI stated that independent auditing of frontier AI was prominently featured in the accord and called the voluntary commitments a step forward, while arguing that audits meeting rigorous standards should ultimately be required for leading AI companies. AVERI and the AI Evaluation Forum are developing audit standards covering auditor independence, minimum access requirements, and audit scope. Around the signing, Trump held a private dinner with Anthropic CEO Dario Amodei and publicly said, "Dario has been fantastic, and we had dinner the other night, and he agrees with everyone. I mean, we all agree". Amodei also met separately with Senate Majority Leader Thune for 20 to 25 minutes.
