# Model Spec

OpenAI has updated its Model Spec, the public description of how it wants its models to behave, reorganizing the guidance around five values: faithfulness to human intent, harm minimization, honesty and transparency, human agency, and care. The previous version spread these commitments across separate principles alongside extensive detailed style guidance; the revision adds guidance on context, oversight and agency, adjusts some behavioral defaults, and retires most of the style detail, while calling the model "GPT" rather than "the assistant." OpenAI says its models do not yet fully reflect the Spec and that results from related training work will come in future updates.
