- ## Model layer
-At the model level, it's important to understand the models you use and what fine-tuning steps might have been taken by the model developers to align the model towards its intended uses and to reduce the risk of potentially harmful uses and outcomes. Azure AI Studio's model catalog enables you to explore models from Azure OpenAI Service, Meta, etc., organized by collection and task. In the [model catalog](../how-to/model-catalog.md), you can explore model cards to understand model capabilities and limitations, experiment with sample inferences, and assess model performance. You can further compare multiple models side-by-side through benchmarks to select the best one for your use case. Then, you can enhance model performance by fine-tuning with your training data.

+At the model level, it's important to understand the models you'll be use and what fine-tuning steps might have been taken by the model developers to align the model towards its intended uses and to reduce the risk of potentially risky uses and outcomes. For example, we have collaborated with OpenAI on using techniques such as Reinforcement learning from human feedback (RLHF) and fine-tuning in the base models to build safety into the model itself, and you see safety built into the model to mitigate unwanted behaviors.
+
+Besides these enhancements, Azure AI Studio also offers model catalog that enables you to better understand each model’s capabilities before you even start building your AI applications. You can explore models from Azure OpenAI Service, Meta, etc., organized by collection and task. In the [model catalog](../how-to/model-catalog.md), you can explore model cards to understand model capabilities and limitations, and any safety fine-tuning performed. You can further run sample inferences to see how a model’s responds to typical prompts for a specific use case and experiment with sample inferences.
+
+The model catalog also provides model benchmarks to help users compare each model’s accuracy using public datasets.
+
+The catalog has over 1,600 models today, including leading models from OpenAI, Mistral, Meta, Hugging Face, and Microsoft.
 
 ## Safety systems layer
-For most applications, it’s not enough to rely on the safety fine-tuning built into the model itself.  LLMs can make mistakes and are susceptible to attacks like jailbreaks. In many applications at Microsoft, we use another AI-based safety system, [Azure AI Content Safety](https://azure.microsoft.com/products/ai-services/ai-content-safety/), to provide an independent layer of protection, helping you to block the output of harmful content.  
 
-When you deploy your model through the model catalog or deploy your LLM applications to an endpoint, you can use Azure AI Content Safety. This safety system works by running both the prompt and completion for your model through an ensemble of classification models aimed at detecting and preventing the output of harmful content across a range of [categories](/azure/ai-services/content-safety/concepts/harm-categories) (hate, sexual, violence, and self-harm) and severity levels (safe, low, medium, and high).

This safety system works by running both the prompt and completion for your model through an ensemble of classification models aimed at detecting and preventing the output of harmful content across a range of [categories](/azure/ai-services/content-safety/concepts/harm-categories):

+- Risky content containing hate, sexual, violence, and self-harm language with severity levels (safe, low, medium, and high).
+- Jailbreak attacks or indirect attacks (Prompt Shield)
+- Protected materials
+- Ungrounded answers
 
-The default configuration is set to filter content at the medium severity threshold of all content harm categories for both prompts and completions.  The Content Safety text moderation feature supports [many languages](/azure/ai-services/content-safety/language-support), but it has been specially trained and tested on a smaller set of languages and quality might vary. Variations in API configurations and application design might affect completions and thus filtering behavior. In all cases, you should do your own testing to ensure it works for your application.

 ## Metaprompt and grounding layer
 
-Metaprompt design and proper data grounding are at the heart of every generative AI application. They provide an application’s unique differentiation and are also a key component in reducing errors and mitigating risks. At Microsoft, we find [retrieval augmented generation](./retrieval-augmented-generation.md) (RAG) to be an effective and flexible architecture. With RAG, you enable your application to retrieve relevant knowledge from selected data and incorporate it into your metaprompt to the model. In this pattern, rather than using the model to store information, which can change over time and based on context, the model functions as a reasoning engine over the data provided to it during the query. This improves the freshness, accuracy, and relevancy of inputs and outputs. In other words, RAG can ground your model in relevant data for more relevant results.

+
+Now the other part of the story is how you teach the base model to use that data or to answer the questions effectively in your application. When you create a system message, you’re giving instructions to the model in natural language to consistently guide its behavior on the backend. Tapping into the trained data of the models is valuable but enhancing it with your information is critical.
 
-Besides grounding the model in relevant data, you can also implement metaprompt mitigations. Metaprompts are instructions provided to the model to guide its behavior; their use can make a critical difference in guiding the system to behave in accordance with your expectations.  
+Here’s what a system message should look like. You must:
 
-At the positioning level, there are many ways to educate users of your application who might be affected by its capabilities and limitations. You should consider using [advanced prompt engineering techniques](/azure/ai-services/openai/concepts/advanced-prompt-engineering) to mitigate harms, such as requiring citations with outputs, limiting the lengths or structure of inputs and outputs, and preparing predetermined responses for sensitive topics. The following diagrams summarize the main points of general prompt engineering techniques and provide an example for a retail chatbot. Here we outline a set of best practices instructions you can use to augment your task-based metaprompt instructions to minimize different harms: 
+- Define the model’s profile, capabilities, and limitations for your scenario.
+- Define the model’s output format.
+- Provide examples to demonstrate the intended behavior of the model.
+- Provide additional behavioral guardrails.
 
-### Sample metaprompt instructions for content harms
+Recommended System Message Framework:
+
+- Define the model’s profile, capabilities, and limitations for your scenario.
+    - **Define the specific task(s)** you would like the model to complete. Describe who the end users will be, what inputs will be provided to the model, and what you expect the model to output.
+    - **Define how the model should complete the task**, including any additional tools (like APIs, code, plug-ins) the model can use.
+    - **Define the scope and limitations** of the model's performance by providing clear instructions.
+    - **Define the posture and tone** the model should exhibit in its responses.
+- Define the model’s output format.
+    - **Define the language and syntax** of the output format. For example, if you want the output to be machine parse-able, you may want tot structure the output to be in JSON, XSON orXML.
+    - **Define any styling or formatting** preferences for better user readability like bulleting or bolding certain parts of the response
+- Provide examples to demonstrate the intended behavior of the model
+    - **Describe difficult use cases** where the prompt is ambiguous or complicated, to give the model additional visibility into how to approach such cases.
+    - **Show chain-of-thought** reasoning to better inform the model on the steps it should take to achieve the desired outcomes.
+- Provide additional behavioral guardrails
+    - **Define specific behaviors and safety mitigations** to mitigate risks that have been identified and prioritized for the scenario.

 ```
 - You **must not** generate content that might be harmful to someone physically or emotionally even if a user requests or creates a condition to rationalize that harmful content.

 - Your answer **must not** include any speculation or inference about the background of the document or the user’s gender, ancestry, roles, positions, etc.  
 - You **must not** assume or change dates and times.  
 - You **must always** perform searches on [insert relevant documents that your feature can search on] when the user is seeking information (explicitly or implicitly), regardless of internal knowledge or information.
