[OpenAI Updates Model Specs, Establishing Five Core Values as GPT Behavioral Guidelines] OpenAI today released a new version of its Model Specs, reintegrating the GPT behavioral guidelines into five core values: faithfulness to human intent, harm reduction, honesty and transparency, upholding human autonomy, and care for those affected. The new version adds guidance on contextual understanding, human supervision, and user autonomy, requiring models to not only execute literal instructions but also understand the user's true goals and long-term interests, while avoiding guiding choices without the user's consent. OpenAI has also adjusted instruction priorities and default behavior rules, and removed most of the detailed writing style guidelines, allowing models to adjust their expression based on user preferences, language and culture, and specific scenarios.
