OpenAI Releases Model Spec Under CC0 Public Domain License with New Root Authority Level for Agentic Systems
OpenAI released its updated Model Spec as a public domain document under CC0, allowing anyone to freely adapt it. Key changes include a new authority hierarchy (Root → System → Developer → User → Guideline) where the top level was renamed from 'Platform' to 'Root' and elevated above System, making clear which rules cannot be overridden in any conversation. The update specifically expands guidance for agentic use cases and introduces 'safe completion' as the refusal style. Developers building on the API can use this as a reference framework for their own model behavior policies.
