Sam Altman's claims

“The very end of 2015, we announced it, and then the first day of work was like January of 2016.”
Sam Altman, OpenAI CEO 4 September 2026 Transcript: Sam Altman Interview on OpenAI, New AI Model and Global Growth - G20 Innovation Summit (Singju Post)
Altman said OpenAI was announced at the very end of 2015 and that its first day of work was around January 2016.
Mostly true True in substance, wrong in a detail.
Said for an organisation they lead or work for; it counts on both records.
What would count as true or false
Judge the substance: OpenAI was announced at the very end of 2015 and started work around January 2016. True: records show the public announcement in late 2015 (December), with the team's first working day in about January 2016. Mostly true: the announcement was in December 2015 but not literally at year-end (e.g. 11 December), or work started in late December or early February. Mixed: only one of the two timing details holds. Mostly false: both are off by a few months but still close to the 2015–2016 transition. False: the announcement or the start of work fell in clearly different periods.

“At the very end of 2015 we announced it, and then the first day of work was like January of 2016.”
Reasoning
TechCrunch's report dated 11 December 2015 (E2) says OpenAI "was announced to the world" that day, and OpenAI's own introduction post carries the same date (E1). So the announcement came in December 2015, though not at the literal end of the year. A third-party summary of a podcast with Altman (E3) puts the first week of operations in early January 2016, which matches the claimed start of work. That summary retells Altman's own account, so the start date is less firmly backed than the announcement date. Under the criteria, an announcement on 11 December with work starting in about January 2016 counts as mostly true.
