What happened
OpenAI published a revised Model Spec that reorganizes its behavioral guidance around five stated values: faithfulness to human intent, harm minimization, honesty and transparency, human agency, and care. The revision adds guidance on context, oversight, and agency, adjusts some behavioral defaults, and retires much of the detailed style guidance. No specific default changes, model versions, API behavior, or dates beyond the October 29, 2026 publication are listed in the text.
Why it matters
The text says some behavioral defaults were adjusted and detailed style guidance retired, but does not say which defaults or what replaced them, so you cannot yet tell whether your prompts, system messages, or agent guardrails need to change. The concrete action is to open the linked Spec and diff the defaults and style sections against what you currently rely on before assuming model tone or refusal behavior is unchanged.
Discussion angle
If behavioral defaults shifted and detailed style guidance was retired, what in your existing system prompts or agent instructions was implicitly relying on that style guidance — and how would you detect the change without a changelog of specific diffs?
