OpenAI rewrites its Model Spec around five values and drops most of its style rules
Published:
OpenAI on 29 October published an updated Model Spec, its public description of how its models should behave. The document is now organised around five values: faithfulness to human intent, harm minimization, honesty and transparency, human agency, and care.
OpenAI says the new section on faithfulness treats what people value as primary, with instructions as the clearest signal of those values, and adds guidance on how conversations, memories and other context should inform the model. The update adds guidance on oversight and agency and adjusts some behavioural defaults.
OpenAI is also retiring most of the Spec's detailed style guidance, saying style should follow user preferences, while keeping stronger defaults such as approaching questions objectively. The Spec now refers to the model as GPT rather than the assistant.
Caveat. OpenAI says the Spec describes the behaviour it is working towards and that its models do not yet fully reflect it.
