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.
This change does not materially affect consumer terms, safeguards, or operational rights. The modification updates a reference list in OpenAI's System Card and does not alter the substantive safeguard language that was established in the April 24, 2026 update.
Updated to reference August 10, 2026 security publication instead of July 28, 2026 scientific computing publication; no safeguard language changed.
