OpenAI updates Model Spec to prioritize human intent, safety and transparency
OpenAI announced an updated Model Spec, its public guide describing how its models should behave. The revision reorganizes guidance around five core values—faithfulness to human intent, harm minimization, honesty and transparency, human agency, and care—and adds new sections on context, oversight, and agency while retiring much of the detailed style guidance.
Key points
- openai reorganized its model spec around five values: intent, harm, honesty, agency, care
- the spec adds guidance on context, oversight, agency and retires most detailed style rules
- openai now calls its models “gpt” in the spec and seeks public feedback on the changes
The update explains that models must go beyond literal instruction following, interpreting user intentions and values, and act wisely when those are incomplete. OpenAI says the Spec now refers to its models as “GPT” and includes a revised chain‑of‑command for resolving instruction conflicts, new defaults for supporting agency and following social norms, and clearer expectations for honesty and harm limits.
OpenAI invites public feedback on the revised Spec, noting that the models do not yet fully meet the described behavior and that future research and deployment experience will guide further refinements.
