OpenAI updates its Model Spec, reorganizing model behavior guidance around five core values
OpenAI published a revised Model Spec on Oct 29, organized around five values: faithfulness to human intent, minimizing harm, honesty and transparency, human agency, and care. It adds guidance on context, memory, personalization and human oversight, adjusts some behavioral defaults, drops most detailed style rules, and now calls the model "GPT" rather than "the assistant".
Why it matters
The Model Spec is OpenAI's public statement of how its models should behave. Moving from itemized rules to core values aims to let models use judgment where instructions are silent, while keeping human oversight.
