The OpenAI GPT-5.5 System Card had its title formatting modified in an update detected on July 15, 2026. The document previously opened with 'GPT-5.5 System Card | OpenAI April 23, 2026 Safety Publication' and the updated version removes the leading 'GPT-5.5 System Card |' text, beginning instead with 'OpenAI April 23, 2026 Safety Publication'. This is a minor editorial or formatting change with no material operational impact on the content, governance provisions, or disclosures within the System Card itself.
