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 OpenAI's headquarters location. While the page includes an image labeled 'OpenAI Offices,' there is no accompanying text specifying that these offices are in San Francisco, CA, or any other location. The claim cannot be verified from this excerpt alone.
