What is meta/llama-guard-4-12b?

Llama Guard 4 12B is Meta's safety content moderation model, free on NVIDIA NIM. Unlike general-purpose chat models, it is specifically designed to detect unsafe content, policy violations, and harmful outputs in AI systems — a specialized tool for building content safety pipelines. Up to 40 RPM, no daily token cap. OpenAI-compatible; requires NVIDIA Developer Program membership and phone verification.
