NoteThe source directly confirms the founding date of December 11, 2015 through the publication date of the official OpenAI announcement blog post. The date appears in the byline ('December 11, 2015') and the post announces the founding of OpenAI with the listed founders. The claim's date format (2015-12-11) is equivalent to the source's format (December 11, 2015) — this is a date precision/format difference, not a contradiction.
