Inside our approach to the Model Spec

OpenAI's Model Spec is a formal framework that explicitly defines how AI models should behave across different situations, including how they follow instructions, resolve conflicts, and operate safely. The document is designed to be public and readable so that users, developers, researchers, and policymakers can understand, inspect, and debate intended AI behavior rather than having it hidden inside training processes. The Model Spec is not a claim that current models already behave perfectly, but rather a target for improvement that OpenAI uses to train, evaluate, and iteratively improve model behavior over time.
