Why this model scores 39.4
Lower capacity and focused classification keep capability, autonomy, and misuse modest, while open licensing and easier local operation maximize deployment.
News tied to gpt-oss-safeguard-20b
The model score of 39.4 rates this model's risk profile. The overall Doom Index of 67.9 measures the complete temporally weighted evidence record. These values answer different questions.
Each article's current Doom Index contribution is divided equally among the exact models named on that article. This prevents multi-model evidence from being claimed in full on several model pages. Model risk scores use a bounded temporal offset around their technical profile, but never feed back into the overall index.
OpenAI releases open-weight safety reasoners backed by deployed classifier practice
OpenAI released 120B and 20B open-weight safeguard models that interpret custom policies, with the underlying safety-reasoning approach already used in production systems.
