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 geographic location (San Francisco, CA, or otherwise) is mentioned in the excerpt. To verify the claim, a source that explicitly states the headquarters address would be required.
