OpenAI Blog · 8 months ago

Two open-weight reasoning models, gpt-oss-safeguard-120b and gpt-oss-safeguard-20b, were developed by post-training gpt-oss models to apply provided safety policies for content labeling. The models come in 120 billion and 20 billion parameter sizes. The technical report establishes baseline safety evaluations comparing the new safeguard models against their underlying gpt-oss predecessors.
