Change Summary
OpenAI's GPT-5 System Card was updated on August 19, 2026 to replace references to three previously linked articles with two newer articles dated August 18, 2026. The change substitutes older content links (published August 1, 10, and 29, 2026) with current references to 'Pacing model development in an era of cyber-critical capabilities' and 'Introducing ChatGPT for Teens'. This is a documentation refresh reflecting current published materials rather than a substantive change to the safety assessment or capability evaluation contained in the system card itself.
