A small organization with a volunteer board, a narrow agenda, and a deliberately cheap experimental program.
As of writing, Separatrix consists of Jai Dhyani, Crystal Stellwagen, and many instances of multiple AI models across multiple contexts.
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 is an experienced software engineer who spends even more time reading papers and running steering-vector experiments than Jai does.
Separatrix operates under the Seattle Network for AI Alignment Problem Solving, a registered non-profit with a volunteer board of directors - Katie Cohen, Keller Scholl, Max Kircher - overseeing all activity and financial transactions.
(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.)
