Change Summary
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.
