Greg Brockmanの戦略的方向性について、Slate公式の報道記事（https://slate.com/technology/2023/11/sam-altman-fired-openai-mira-murati.html）で確認できます。Existing references describe Brockman only via OpenAI's own official site (co-founder/president, leading infrastructure development); none mention the November 2023 leadership crisis, his resignation, or his public statements, so there is no overlap.具体的には「'based on today's news, i quit' — Brockman's statement via Twitter after the firing announcement. Greg Brockman is 'stepping down as chairman of the board.' On Friday night, Brockman and Altman released a joint statement from the former's X/Twitter account expressing they were 'shocked and saddened by what the board did.'」といった記載が確認できます。限界として、これは当該Source公表時点の方針表明であり、その後変更される可能性があります。 This source covers events specifically on and immediately after November 17, 2023; it explicitly does not address Brockman's later move toward Microsoft or his eventual return to OpenAI as CEO-reinstated-Altman's colleague, which occurred in the following days.Current Statusとして、2026年08月27日に当該Sourceを取得し、上記の内容を確認しました。Source種別としては、これは第三者であるSlateによる報道であり、企業の自己申告とは性質が異なりますが、報道時点の取材内容に基づくものです。
