OpenAI updates Model Spec, organizing model behavior around five core values

An updated Model Spec for more capable and beneficial AI

OpenAI has updated its Model Spec, regrouping the rules for model behavior around five core values: following human intent, reducing harm, honesty and transparency, human autonomy, and care. The revision updates the instruction hierarchy, adds guidance on context, human autonomy and social norms, expands requirements on side-effect control and communication, and removes most detailed style guidance. OpenAI says it is exploring training methods to match, but states plainly that current models do not yet fully reflect the spec.

Why it matters: The spec now ties model behavior to five core values, giving clearer grounds for how models should weigh human intent and autonomy when instructions run out.
