Change Summary
OpenAI's GPT-5 System Card was revised in an update detected on September 9, 2026. The change removed the header 'GPT-5 System Card' from the opening line and updated the 'Keep reading' section, replacing three related articles (An Alien Mind, Research acceleration, and Safety overview) with three different articles dated September 6-8, 2026. The operational significance is limited; this appears to be a routine update to the document's internal cross-references and navigation elements rather than a substantive change to the model's capabilities, safety thresholds, or disclosed risks.
