Donald Trump, Sundar Pichai (Google), Dario Amodei (Anthropic), Mark Zuckerberg (Meta), Greg Brockman (OpenAI), Elon Musk (xAI) and Jensen Huang (Nvidia) signed the White House Accord on Super Intelligence on Tuesday, September 29, at a White House lunch. Trump then posted the full text on Truth Social, per CNBC and AP. The document is titled "Joint Commitment on Frontier Responsibilities." Trump called it "almost like a constitution" and "morally binding," according to CBS, ABC, CNBC and Bloomberg.
What the four layers require
The accord holds that every company is responsible for developing its own technology safely. Each company training and deploying frontier models is asked to implement four layers of controls and audits:
- Internal controls that monitor model capabilities and alignment during training and deployment, in areas like cybersecurity, biosecurity and chemical threats, and that ensure models do not hack or access technical systems in unintended ways.
- An internal team that verifies those controls, monitoring and detection work as intended and that issues are remediated.
- An independent external auditor or evaluator that assesses whether the controls are operating as intended.
- An independent committee of the board of directors that oversees and receives reports from the control teams and from the internal and external auditors, and ensures identified issues are fixed.
The participating companies will meet regularly to set standards and best practices. The text adds that "over time, it may make sense to codify these steps into laws or regulations."
Who signed, who attended, who did not
Nearly two dozen executives attended, per Bloomberg. Axios, CNBC and Fox report that Microsoft's Satya Nadella, Jeff Bezos, AMD's Lisa Su, Broadcom's Hock Tan, Palantir's Alex Karp and Micron's Sanjay Mehrotra were there but did not sign. Sam Altman was at OpenAI DevDay in San Francisco, per AP and CNBC, and Brockman signed for OpenAI. The same day, Trump signed a separate executive order renaming "artificial intelligence" as "Super Intelligence" across the executive branch, per AP, CNBC and Fox.
Voluntary, with no penalties or deadlines
Speaker Mike Johnson called the accord "voluntary" and said Congress would "continue to assess and further deliberate," per CNBC and Roll Call. Bloomberg reports the document carries no legal weight, and the text sets no penalties or deadlines. Codification is only floated as something that "may make sense."
Bloomberg still sees a shift in the third clause. Officials had been skeptical of the groups best placed to run such reviews, over their perceived ideological leanings, and the accord now endorses independent evaluators; the industry, Bloomberg says, had "clamored" for them. Under the text, each company partners with its own external auditor.
Per Benzinga, Zuckerberg called it a "significant positive step," citing "strong internal controls and multiple layers of audits and reviews," and Musk replied "Yes." Pichai called it "a solid foundation to move forward." Senator Elizabeth Warren said: "Self-regulation? That's a recipe for disaster." Gary Marcus questioned what "independent" means in practice, and The Register called the accord weak and non-binding.
How it follows the pacing debate
The accord lands seventeen days after Amodei's September 12 essay, which proposed third-party evaluators embedded inside labs. Clause three is the closest government-endorsed echo of that idea, though it asks for assessments rather than embedded staff. Nadella had endorsed embedded evaluators and attended the lunch without signing.
Between the essay and the accord came Trump's September 13-14 posts, reported by Bloomberg, CNBC and NPR, saying the only guardrail AI needs is a strong president; this blog covered them in Trump's AI guardrails reply to Amodei. Zuckerberg's September 16 stance was that market incentives are the main check. OpenAI's misalignment reporting framework kept reporting inside the company, whereas the accord's third and fourth clauses require reports to reach an outside auditor and a board committee.
