AI companies shouldn't grade their own homework. More and more of the AI world now agrees. The answer is IVOs: testers independent from the labs, licensed by the government, and competing on quality. More from our CEO @AndrewFATHOM ⬇️
A lot of new voices have joined the conversation on independent verification of AI models and systems in the last few weeks. AI labs, major U.S. corporations, state and federal lawmakers in both parties are all calling for it. Having pushed for this framework for AI governance at @Fathom_org for years, it’s wild to see “independent verification organizations” (IVOs) flash across prime time television.

On Monday, 20 countries and the EU called for pre-deployment testing and independent evaluation of frontier AI. Canada, Australia, Singapore and the EU signed. All four are in our new report on what makes a country ready to build a third-party evaluation ecosystem.

Thanks to @BCWtweeting and the Summit County GOP for having me on The Chairman's Hour. We talked AI, HB 628, and why Ohio should let independent experts verify AI products are safe, not just the companies that build them. Give it a listen 🎧 omny.fm/shows/chairmans-hour…

Thank you @CAgovernor for asking me to join the group of experts advising California on AI safety and security governance. The EO tasks us to explore roles for IVOs, which builds on my work with @Fathom_org, including assessing the efficacy of a kill switch and the adequacy of frontier labs’ safety frameworks.

Exciting news out today: Dr. Gillian Hadfield, a Fathom senior advisor and one of our closest partners, has been named to the group of experts to advise the state on its AI executive order. Dr. Hadfield is a key architect of the IVO framework we champion: a market of independent technical experts licensed by and accountable to the government. Congrats @ghadfield on your inclusion in the group of experts, you will be an invaluable asset to California and policymakers and help ensure IVOs are brought to life the right way.

On Friday, Governor Newsom signed an executive order that accelerates the implementation of IVOs in California. It also asks leading experts where independent verification could play a bigger role. More from @AndrewFATHOM in @POLITICOPro's California Decoded ⬇️

World leaders arrive in New York this week with AI governance on the agenda. But readiness for independent verification may have less to do with technological sophistication than with politics. What determines where it can take root first? Read our latest report ⬇️

"We're not gonna let the companies just report their own definition of what they think is safe... Let's bring in some third-party verifiers to do that checking." @Jason_Elliott on SB 813: IVOs independent from the labs they assess, designated by the state. Verification means the risks to businesses, children and families, and society can be independently assessed rather than simply taken on faith.
"It's a way to stop out of control AI from doing things you don't want it to do." @CAgovernor signed an executive order to create a panel of experts to help implement an AI "kill switch" and to independently verify what the companies are doing. @Jason_Elliott, @GavinNewsom's former deputy chief of staff, says states like California need to step up after the federal government hasn't put forth enough regulations.

Massachusetts Gov. Maura Healey is urging lawmakers to require independent safety evaluations of the most powerful AI models in the Mass Wins Act, not just company self-reporting. "Self-assessment alone is not sufficient," she wrote to the conference committee.

Fathom has been pushing for exactly this alongside a coalition of academics, AI safety organizations, and independent evaluators. We thank Governor Healey for making the case at this important moment.
