WASHINGTON — The Frontier Model Assurance Council, the industry-funded body established under the May Eighth voluntary disclosure framework, named its first deputy director Sunday afternoon, with the appointment formalizing senior oversight of the Council’s pre-deployment review function and signaling the body’s transition from an interim startup configuration to a sustained operational posture.

The deputy director, whose appointment was announced through the Council’s secretariat in a Sunday-afternoon communication to signatory companies and to federal-government counterparts, is Dr. Jennifer Park, the former senior research director at the Stanford Center for Human-Compatible AI and a previously published researcher on AI evaluation methodologies. Park is scheduled to begin her duties on June 1 following a two-week transition period.

Park’s appointment had been preceded by a four-month search process conducted by the Council’s nominating committee, which had been operating under the framework’s interim leadership structure since the framework’s pre-adoption period in early March. The committee had reviewed approximately forty initial candidates and had conducted substantive interviews with eight finalists during the past three weeks. The committee’s recommendation was confirmed by the Council’s interim board Sunday morning.

Interim Director Pavithra Ramaswamy, in a Sunday-afternoon statement, said Park’s appointment “establishes the substantive complement of senior operational leadership” required for the Council’s review function and indicated that the appointment had been “broadly endorsed” by the framework’s signatory companies. Ramaswamy noted that Park’s appointment had been timed to coincide with the framework’s transition into its second operational test, the recently filed OpenAI pre-deployment notice.

Park, in a brief statement issued through the Stanford communications office Sunday afternoon, characterized the role as “the most substantively important opportunity in the contemporary AI policy landscape” and indicated that she would conclude her current Stanford responsibilities through the end of May. Park’s substantive research over the past five years has focused on AI evaluation methodologies, particularly the substantive question of how to assess capability thresholds for frontier models without requiring full white-box access to the model’s underlying parameters.

Park’s substantive responsibilities at the Council will include direct oversight of the pre-deployment review function, with specific authority over the Council’s internal review team’s substantive evaluation methodologies and over the external technical-consultation process that the framework permits during the review window. The deputy director will also have substantive responsibility for the Council’s interactions with federal regulatory counterparts, including the Treasury Department’s grid-impact rulemaking team and the Cybersecurity and Infrastructure Security Agency’s emerging-technology threat-analysis team.

The Council’s signatory companies — Anthropic, OpenAI, Google, Microsoft, and Meta — have each confirmed their substantive endorsement of Park’s appointment through Sunday-afternoon statements issued through their respective government-affairs channels. A senior Anthropic government-affairs official, in a brief background statement, said the company viewed Park’s appointment as “substantively strengthening the framework’s operational capacity at a critical moment in its development.”

The Council’s interim board, which has been operating since the framework’s adoption with five members drawn from the signatory companies and three external members, is expected to be reconstituted with Park’s appointment as part of the framework’s transition to its sustained operational configuration. The reconstituted board will include nine members, with five drawn from the signatory companies and four external members representing the academic, civil-society, and federal-government communities.

Senator Maggie Hennessey, D-Colo., in a Sunday-afternoon statement, characterized Park’s appointment as “exactly the substantive leadership profile the Council requires” and indicated that her office’s substantive engagement with the Council on the Hennessey-Blackburn AI Transparency and Grid Impact Act would be substantively informed by Park’s substantive priorities. Senator Marsha Blackburn, R-Tenn., issued a parallel statement endorsing Park’s appointment.

A senior official at the National Institute of Standards and Technology’s AI Risk Management Center, in a Sunday-afternoon background statement, characterized Park’s substantive research profile as “directly relevant” to the Council’s substantive responsibilities and indicated that NIST’s substantive engagement with the Council would be “substantially advanced” by Park’s appointment. NIST has been one of the federal-government’s principal substantive interfaces with the framework through its first eight days of operation.

The Hennessey-Blackburn bill’s first Senate Commerce Committee markup, scheduled for early June, is expected to substantively reference the Council’s institutional structure and the role of the deputy director position in the bill’s substantive provisions. Senator Hennessey’s office has indicated that the bill’s substantive content has been “informed” by the Council’s institutional design but has not been pre-committed to the Council’s specific operational framework.

The Council’s first substantive review under Park’s deputy-director responsibility will be the OpenAI pre-deployment notice filed Saturday afternoon, which entered the framework’s sixty-day review window upon its filing. Park’s appointment timing has been calibrated to permit her to take operational responsibility for the OpenAI review’s substantive midpoint and conclusion phases, which fall in June and July respectively.

The Council’s third operational test, expected to be a Google pre-deployment notice during the late-summer window, will be the first review conducted entirely under Park’s deputy-director responsibility. The Google filing’s specific timing has not been confirmed by the company, but senior Google officials have indicated that the substantive preparation for the filing has been proceeding through the past three weeks.

The Council’s broader institutional buildout will continue through the summer, with the framework’s substantive operational evaluation scheduled for the framework’s three-month review point on August 8. The August review’s substantive content has not been pre-specified but is expected to assess the framework’s procedural efficiency, the substantive quality of pre-deployment notices, and the Council’s review-capacity adequacy.
