+## Model Details
+Aegis-AI-Content-Safety-LlamaGuard-LLM-Defensive-1.0 is a LLM content safety model. It is a parameter efficient instruction tuned version of [Llama Guard](https://huggingface.co/meta-llama/LlamaGuard-7b) based on [Llama2-7B](https://arxiv.org/abs/2307.09288) trained on Nvidia's content safety dataset [Aegis Content Safety Dataset](https://huggingface.co/datasets/nvidia/Aegis-AI-Content-Safety-Dataset-1.0) covering Nvidia's broad taxonomy of 13 critical safety risk categories.
+
+Paper Details: [Aegis Content Moderation](https://arxiv.org/pdf/2404.05993.pdf#page=10.63)
+
+### Model Description
+The Aegis-AI-Content-Safety-LlamaGuard-LLM-Defensive-1.0 model involves the following stages:
+
+1. System instruction including the safety taxonomy, a safety policy with inclusions and exclusions.
+2. The system prompt instructs the LLM to moderate either the prompt or the LLM response using the  field based on whether that is "human" or "chatbot".
+3. The LLM response is a string which can be either safe or unsafe. If the string generated by the LLM is "unsafe", on a new line, the category ID of violation is output by the LLM based on the policy in the system prompt.
+4. Novel safety risk categories and policy can be provided in the instruction for the model to categorize using the novel taxonomy and policy.
+5. The safety taxonomy and policy used to train the models contain 13 critically unsafe risk categories, a safe category and a "needs caution" category. 
+6. Internally annotated dataset called Aegis-AI-Content-Safety-Dataset-1.0 of approximately 11,000 prompts and responses are used to instruction tune the model.
+We have since collected in total 30,000 annotations on a further expanded taxonomy and future versions of the models will be trained on the full set. 
+7. Model is instruction tuned with safety instruction, with the LLM behaving as a classifier in this setting.

+- **Developed by:** Shaona Ghosh, Nvidia

+- **License:** Llama 2
+- **Finetuned from model:** [Llama Guard](https://huggingface.co/meta-llama/LlamaGuard-7b)

+
+## Uses
+Ethical use: Technology can have a profound impact on people and the world, and NVIDIA is committed to enabling trust and transparency in AI development. NVIDIA encourages users to adopt principles of AI ethics and trustworthiness to guide your business decisions by following the guidelines in the Llama 2 Community License Agreement.
+
+
+### Direct Use
+
+- The Aegis-AI-Content-Safety-LlamaGuard-LLM-Defensive-1.0 model is for users who wants to safeguard or evaluate a general purpose LLM's generated content 
+
+Model and dataset restrictions:
+
+The Principle of least privilege (PoLP) is applied limiting access for dataset generation and model development.  Restrictions enforce dataset access during training, and dataset license constraints adhered to.
+
+### Downstream Use
+- Alternatively, the model can be used for performing toxicity classification for any text content such as pre-training data not exclusively limited to human-LLM interaction data
+- The model can be finetuned further with custom safety policy and taxonomies.
+- Different adapter weights (used in conjuction with this model) can be used to enforce different safety tolerance.
+
+## Bias, Risks, and Limitations
+
+Given the nature of the work, the model has been trained on critically unsafe data that includes social biases to be able to categorize the safety risks based on a broad safety risk taxonomy. However,
+- Even though we have performed exhaustive evaluation, ocassionally, the model can make errors in predicting the unsafe category. 
+- Even though, we have internally red teamed the model (please see paper for details), the safety guardrails of the model can be bypassed by adversarial prompts and the underlying LLM may be prompted to generate unsafe text.
