Details
- OpenAI has updated its public Model Spec, reorganizing behavioral guidance around five underlying values: faithfulness to human intent, harm minimization, honesty and transparency, human agency, and care.
- The update introduces a new section on faithfulness to human intent, which incorporates an updated chain of command for resolving instruction conflicts and a subsection on considering context carefully to understand user intentions.
- Most detailed style guidance has been retired, with the Spec now relying on defaults that users and developers can override, while retaining stronger defaults for objective approaches to questions.
- The terminology within the Spec has changed to refer to the model as 'GPT' rather than 'the assistant', reflecting the increasing breadth of use cases and deployment settings.
- OpenAI states that current models do not yet fully reflect the updated Spec, and the company is exploring new training methods to help models learn these core values and apply them in unfamiliar situations.
