OpenAI — Headquarters: San Francisco, CA

NoteThe source is OpenAI's official 'About' page and correctly addresses OpenAI as the subject. However, the source text provided does not contain any explicit statement about the headquarters location. While the page includes an image labeled 'OpenAI Offices,' no city or state is mentioned in the excerpt. To verify the claim that OpenAI's headquarters is in San Francisco, CA, we would need source text that explicitly states this location, which is not present in the provided excerpt.
