OpenAI's GPT-5.5 System Card was updated on July 11, 2026 to modify the list of related research and product announcements displayed at the bottom of the card. The previous version linked to a July 8 research article on coding evaluations as the most recent item; the updated version replaces that link structure with references to an OpenAI Bio Bug Bounty Safety announcement dated July 9, 2026. This change updates the associated content and dates but does not alter the substantive safeguard information, deployment guidance, or technical safety documentation contained in the System Card itself.
