OpenAI changed the text of its OpenAI GPT-5.5 System Card.

OpenAI's GPT-5.5 System Card was updated on September 7, 2026, to modify the list of related safety and research content displayed on the card. A reference to 'The Hugging Face incident and the road ahead' from August 26, 2026 was removed from the navigation, and two new entries were added: 'An Alien Mind' from September 6, 2026 and 'Research acceleration: The view inside OpenAI Research' also from September 6, 2026. This change affects which safety-related documents and incident analyses are linked alongside the GPT-5.5 deployment guidance.

OpenAI's GPT-5.5 System Card was updated in an update detected on September 2, 2026. The updated document removed two older blog post links (one about pacing model development from August 18, 2026, and one about securing cyber-critical capabilities from an unspecified date) and added a new link titled 'Path to Astra: critical capabilities and frontier safeguards' dated September 1, 2026. The change reflects the document's table of contents and does not alter the substantive safety disclosures or risk assessments within the system card itself.

OpenAI's GPT-5.5 System Card was updated on August 27, 2026 to revise its introductory metadata and add a reference to a security incident discussion. The change replaced outdated blog post listings with a new entry titled 'The Hugging Face incident and the road ahead' dated August 26, 2026. This appears to be a routine metadata refresh directing readers to current security-related content rather than a substantive change to the model's documented safeguards or deployment practices.

OpenAI's GPT-5.5 System Card was updated in an update detected on August 20, 2026. The change involved removing references to three previously listed company and product announcements (Expanding Daybreak as the Cyber Defense Window Narrows, Pacing model development in an era of cyber-critical capabilities, and Introducing ChatGPT for Teens) and adding a new announcement link titled 'Offering Zero Data Retention for frontier models' dated August 19, 2026. This is an editorial change to the card's navigation and related-content section, reflecting current publication links rather than a change to the substantive safeguards or deployment terms described in the system card itself.

OpenAI's GPT-5.5 System Card was detected as updated on August 19, 2026. The change modified the featured content links in the document's header section, replacing three dated articles (published August 10, August 1, and July 29, 2026) with two newer articles published August 18, 2026, including new content on 'Pacing model development in an era of cyber-critical capabilities' and 'Introducing ChatGPT for Teens'. The System Card itself, which documents safeguards for GPT-5.5 and GPT-5.5 Pro deployment, remains substantively unchanged; only the curated links to related resources were updated.

OpenAI's GPT-5.5 System Card, last substantively updated on April 24, 2026, was modified on August 11, 2026. The change replaced a reference to a July 28, 2026 publication ('Scientific computing in the age of agentic AI') with a reference to an August 10, 2026 security publication ('Expanding Daybreak as the Cyber Defense Window Narrows'). This is a minor change to the 'Keep reading' section that directs readers to related OpenAI publications and does not modify any substantive safeguard disclosures or capability descriptions in the System Card itself.

OpenAI's GPT-5.5 System Card was updated in an update detected on August 2, 2026. The change replaced one research publication link in the card's header with a different publication. Specifically, the link to 'Safety and alignment in an era of long-horizon models' (dated July 20, 2026) was removed and replaced with 'Ten advances in mathematics and theoretical computer science' (dated August 1, 2026). This is an editorial update to the featured research content displayed on the system card and does not modify the substantive safeguards documentation or deployment guidance for GPT-5.5.

OpenAI updated the GPT-5.5 System Card detected on July 30, 2026. The change replaced three featured research and safety articles in the document's header with two different research publications. The prior version linked to articles on 'Safety and alignment in an era of long-horizon models' (Jul 20), 'Why teens deserve access to safe AI' (Jul 16), and 'GPT-Red: Unlocking Self-Improvement for Robustness' (Jul 15). The updated version now links to 'How enabling two settings tripled our scores on the ARC-AGI-3 benchmark' (Jul 29) and 'Scientific computing in the age of agentic AI' (Jul 28), while retaining the safety alignment article. This is a navigation and featured content update with no material change to the system card's substantive governance or safety disclosures.

OpenAI's GPT-5.5 System Card was updated in an update detected on July 21, 2026. The document removed a reference to an article titled 'GPT-Red: Unlocking Self-Improvement for Robustness' published July 15, 2026, and added a new reference to 'Safety and alignment in an era of long-horizon models' published July 20, 2026. This change updates the list of related safety resources linked from the system card to reflect the most recent OpenAI safety research publications.

OpenAI updated the GPT-5.5 System Card on April 24, 2026, to include safeguards information. In an update detected on July 18, 2026, a single sentence was modified in the card's reference section. The change replaced a link to one safety-related article (Separating signal from noise in coding evaluations, July 8) with a different safety article (Why teens deserve access to safe AI, July 16). This affects which recent safety publications are highlighted in the system card's navigation.

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.

OpenAI updated the GPT-5.5 System Card on July 9, 2026 by modifying the related research links displayed alongside the card. The updated version replaced two previously listed research articles with a newly published article titled 'Separating signal from noise in coding evaluations' dated July 8, 2026. This change appears to be a routine update to keep featured research current rather than a modification to the system card's substantive safety, deployment, or governance information.
