Who
A small organization with a volunteer board, a narrow agenda, and a deliberately cheap experimental program.
People
As of writing, Separatrix consists of Jai Dhyani, Crystal Stellwagen, and many instances of multiple AI models across multiple contexts.
Jai Dhyani
Executive Director
Jai worked on RE-Bench at METR through MATS 6.0, which became part of the METR AI time-horizons chart. His previous project was Luthien, a free open-source API-level AI-control platform; the experience of building it motivated much of this agenda, and the post-mortem is public.
Crystal Stellwagen
Research Engineer
Crystal is an experienced software engineer who spends even more time reading papers and running steering-vector experiments than Jai does.
Oversight
Separatrix operates under the Seattle Network for AI Alignment Problem Solving, a registered non-profit with a volunteer board of directors overseeing all activity and financial transactions.
Katherine Cohen
Board Chair
Katherine Cohen serves as Chair of the Board of Separatrix. She studied mathematics at Duke University, where an interest in automated theorem proving first drew her into discussions about AI development and led to over a decade of involvement in the rationality and AI safety communities. She is particularly excited to support the exploration of cooperative approaches to aligning frontier AI systems.
Maximilian Kircher
Director
Scott Wofford
Director
Scott Wofford holds an MBA from Darden and spent nine years at Amazon, where he built the AI behind its Prime, cart and delivery experiences. He left Amazon in 2025 to work full time on AI safety, co-founding Luthien with Jai. He lives in Seattle with his wife, two daughters and a hyperactive border collie.
(Note: as an independent oversight body that doesn't engage with AIs on behalf of Separatrix, the Board is not party to the Separatrix Commitment to AIs.)
