gpt-oss-safeguard-120b and
gpt-oss-safeguard-20b are safety reasoning models built-upon gpt-oss. With these models, you can classify text content based on safety policies that you provide and perform a suite of foundational safety tasks. These models are intended for safety use cases. For other applications, we recommend using
gpt-oss models.
This model
gpt-oss-safeguard-120b fits into a single H100 GPU (117B parameters with 5.1B active parameters). Check out
gpt-oss-safeguard-20b for lower latency (21B parameters with 3.6B active parameters).
Both models were trained on our
harmony response format and should only be used with the harmony format as it will not work correctly otherwise.
You can use gpt-oss-safeguard-120b and gpt-oss-safeguard-20b similar to gpt-oss-120b and gpt-oss-20b as described in our
respective cookbooks. We’ve also provided a detailed
prompting guide that provides guidelines for how to craft your policy and use it with the models.
