We do know that Pavel Izmailov has joined xAI: https://izmailovpavel.github.io/
He removed the mention of xAI, and listed Anthropic as his next job (in all his platforms).
His CV says that he is doing Scalable Oversight at Anthropic https://izmailovpavel.github.io/files/CV.pdf
His LinkedIn also states the end of his OpenAI employment as May 2024: https://www.linkedin.com/in/pavel-izmailov-8b012b258/
Leopold Aschenbrenner still lists OpenAI as his affiliation everywhere I see.
His twitter does say “ex-superalignment” now: https://x.com/leopoldasch?lang=en
