OpenAI — Headquarters: San Francisco

Note: The source directly confirms that OpenAI's headquarters is/was in San Francisco. The image captions explicitly reference San Francisco as the location of OpenAI's headquarters (both current and former). While one caption uses 'ancien siège social' (former headquarters), suggesting a possible relocation, the Norwegian caption uses present tense 'har hovudkvarter' (have headquarters), and the Wikidata entry itself does not specify an end date for the San Francisco location in the visible text. The claim is confirmed by the source material.
