OpenAI unveils open-weight AI safety models for developers

OpenAI has introduced the 'gpt-oss-safeguard' family of open-weight models, including the 120-billion and 20-billion parameter versions, designed to empower developers with customizable safety controls for content classification. These models, released under the permissive Apache 2.0 license, enable organizations to freely modify and deploy them, shifting the safety paradigm from fixed rules to reasoning-based interpretation aligned with specific policies at inference time. Unlike traditional black-box classifiers, the 'gpt-oss-safeguard' models utilize a chain-of-thought reasoning process, allowing developers to understand and
