Personnel: Mark Zuckerberg at Meta AI (FAIR) (Founder & CEO)

Note: The record claims Mark Zuckerberg is at 'Meta AI (FAIR)' with the role 'Founder & CEO'. The source text provided is a Wikipedia biography that comprehensively covers his career, roles, and organizations. It explicitly lists his titles as co-founder/chairman/CEO of Meta Platforms and Facebook, and co-founder/co-CEO of Chan Zuckerberg Initiative, but makes no mention of Meta AI (FAIR) or any role there. Since the source does not address this specific claim about Meta AI (FAIR), it cannot be verified or contradicted from the provided text. This is a case of 'wrong source relevance' — the source discusses Zuckerberg's roles but does not cover the specific organization in question.
