NoteThe source text clearly displays 'December 11, 2015' as the publication date of the founding announcement blog post. The source also confirms the founding members mentioned in the additional context (Greg Brockman, Ilya Sutskever, Sam Altman, Elon Musk, Wojciech Zaremba, and John Schulman are all listed). The date format in the claim (2015-12-11) is equivalent to the source's date (December 11, 2015) — this is a standard ISO 8601 vs. written-out date format difference, which is not a contradiction.
