OpenAI·medium signal

OpenAI released a comprehensive framework for frontier AI governance alongside a detailed playbook for conducting trustworthy third-party model evaluations. The playbook addresses how to evaluate systems like GPT-5.5 where traditional chatbot-style assessments are inadequate, requiring detailed documentation of what system was tested, how results were elicited, and validity checks. Could serve as a blueprint for EU AI Act and California's Transparency in Frontier AI Act implementation.
