Change Summary
OpenAI's GPT-5 System Card was updated on July 18, 2026, with a modification to the document's linked content references. The change replaced references to three previously linked articles ('Separating signal from noise in coding evaluations', 'Introducing GeneBench-Pro', and a generic 'View all' link) with two new articles titled 'Why teens deserve access to safe AI' and 'GPT-Red: Unlocking Self-Improvement for Robustness'. The substantive text of the system card remains unchanged; only the curated set of related documents and safety research linked from the card has been updated.
