NoteThe claim states 'OpenAI Foundation's Founded Date = 2015-12' (December 2015). The source confirms that OpenAI was founded in 2015, but does not specify December. More critically, the source explicitly states that the nonprofit 'is now the OpenAI Foundation' as of October 28, 2025—meaning the OpenAI Foundation as an entity was created/renamed in October 2025, not founded in December 2015. The original entity founded in 2015 was 'OpenAI' (a nonprofit), which was later renamed to 'OpenAI Foundation' in 2025. The claim conflates the founding date of the original OpenAI nonprofit (2015) with the founding date of the entity called 'OpenAI Foundation' (2025). If the claim is specifically about when the entity named 'OpenAI Foundation' was established, the answer is October 2025, not December 2015.
