Summary
Llama 3.1 NemoGuard 8B ContentSafety NIM is a GPU-accelerated content-moderation NIM for trustworthy LLM applications. Current NVIDIA docs describe it as detecting harmful content in user messages or bot responses.
Detail
Purpose
ContentSafety NIM gives applications a deployable safety classifier for input and output moderation. It can be called directly through NIM endpoints or integrated into NeMo-Guardrails content-safety rail flows.
Current scope
- Detects harmful content in user messages and bot responses.
- Trained by NVIDIA from a Llama 3.1 8B Instruct base model.
- Uses the Nemotron Content Safety Dataset V2 lineage, formerly Aegis AI Content Safety Dataset 2.0.
- Exposes standard NIM LLM endpoints such as completions and chat completions.
- NeMo Guardrails integrates through LangChain ChatNVIDIA and a
content_safetymodel configuration.
NVIDIA context
ContentSafety NIM is the earlier NemoGuard content-safety NIM lineage. The newer Llama-3.1-Nemotron-Safety-Guard-8B-NIM covers multilingual Safety Guard V3; both remain useful query targets for NVIDIA content moderation.
