Aegis AI Content Safety
NVIDIANVIDIA's content-safety classifier (now also called Llama Nemotron Safety Guard Defensive), a LlamaGuard/Llama2-7B-based model parameter-efficiently tuned on NVIDIA's Aegis safety dataset to classify prompts and responses across 13 critical risk categories.
NVIDIA Aegis AI Content Safety (Defensive 1.0), also called Llama Nemotron Safety Guard Defensive V1. The adapter weights are on the Hub while the Llama Guard base needs Meta's access request, which the openness axis weighs. The Aegis dataset it was tuned on is published.

Openness
3 medium confidence- weights
- adapter-open(HF) but base LlamaGuard gated via Meta access
- data
- Aegis safety dataset documented
- license
- Llama-2-Community(NOT OSI)
Open-weights at the adapter level but the LlamaGuard base is access-gated through Meta and the license is the non-OSI Llama 2 Community License, so it lands at open_weights (3) with a gating caveat.

License section reads 'The use of this model is governed by the Llama 2 Community License Agreement'. The repo is not gated and carries adapter_model.safetensors, so the adapter is downloadable; the model is a parameter-efficient tune of Llama Guard, whose own repo is access-gated. cardData declares datasets - nvidia/Aegis-AI-Content-Safety-Dataset-1.0, covering the 13-category taxonomy.

Capability
4 low confidenceBroad risk taxonomy with a documented training dataset. Aegis is itself a tune of Llama Guard and covers a taxonomy of the same order - 13 categories against Llama Guard's 14 - so it sits at the same rung as its base.
