We'll wrap the section by understanding the application lifecycle (GenAIOps) and the three stages for end-to-end development that we will follow in this workshop. + +--- + +## 1. The App Scenario + +**Contoso Outdoors** is an enterprise retailer that sells a wide variety of hiking and camping equipment to outdoor adventurer through their website. Customers visiting the site often call the customer support line with requests for product information or recommendations, before making their purchases. The retailer decides to build and integrate an AI-based _customer support agent_ (retail copilot) to handle these queries right from their website, for efficiency. + +![Contoso Chat UI](./img/chat-ui.png) + +**Contoso Chat** is the chat AI implementation (_backend_) for the retail copilot experience. It has a hosted API (_endpoint_) that the chat UI (_frontend_) can interact with to process user requests. Customers can now ask questions in a conversational format, using natural language, and get valid responses grounded in product data and their own purchase history. + +![Contoso Chat AI](./img/chat-ai.png) + +## 2. The RAG Pattern + +Foundation large language models are trained on massive quantities of public data, giving them the ability to answer general questions effectively. However, our retail copilot needs responses grounded in _private data_ that exists in the retailer's data stores. _Retrieval Augmented Generation_ (RAG) is a design pattern that provides a popular solution to this challenge with this workflow: + +1. The user query arrives at our copilot implementation via the endpoint (API). +1. The copilot sends the text query to a **retrieval** service which vectorizes it for efficiency. +1. It uses this vector to query a search index for matching results (e.g., based on similarity) +1. The retrieval service returns results to the copilot, potentially with semantic ranking applied. +1. The copilot **augments** the user prompt with this knowledge, and invokes the chat model. +1. The chat model now **generates** responses _grounded_ in the provided knowledge. + +![RAG](./img/rag-design-pattern.png) + +## 3. The App Architecture + +Implementing this design pattern requires these architectural components: + + - an **information retrieval** service (data indexing, similarity search, semantic ranking) + - a **database** service for storing other data (customer orders) + - a **model deployments** capability (for chat, embeddings - and AI-assisted evaluation) + - a **copilot hosting** capability (for real-world access to deployed endpoint) + +The corresponding Azure AI application architecture for the Contoso Chat retail copilot is shown below. The copilot is deployed to Azure Container Apps, providing a hosted API endpoint for client integration. The copilot processes incoming requests with the help of: + + - **Azure OpenAI Services** - provides model deployments for chat and text embeddings + - **Azure CosmosDB** - stores the customer order data (JSON) in a noSQL database + - **Azure AI Search** - indexes the product catalog with search-retrieval capability. + +![ACA Architecture](./img/aca-architecture.png) + +The copilot _orchestrates_ the steps of the RAG workflow using **Prompty** assets (configured with required Azure OpenAI models) executed in a Prompty runtime (Python). It supports multi-turn conversations and responsible AI practices to meet response quality and safety requirements. + +## 4. The App Lifecycle + +Building generative AI applications requires an iterative process of refinement from _prompt_ to _production_. The application lifecycle (GenAIOps) is best illustrated by the three stages shown: + +1. **Ideation** - involves building the initial prototype, validating it manually with a test prompt. +2. **Evaluation** - involves assessing it for quality and safety with large, diverse test datasets. +3. **Operationalization** - involves deploying it for real-world usage & monitoring it for insights. + +![GenAIOps](./img/gen-ai-ops.png) + +In our workshop, you willl see the development workflow organized into sections that mimic this lifecycle - giving you a more intuitive sense for how you can iteratively go from promt to production, code-first, with Azure AI. + +## 5.

In this section, we'll learn how to assess the _quality_ of responses from our application using a 3-step workflow: - -1. We define a representative set of test inputs in a JSON file (see `evaluators/data.jsonl`) -1. Our application processes these inputs, storing the results (in `evaluators/results.jsonl`) -1. Our evaluators grade results for 4 quality metrics (in `evaluators/eval_results.jsonl`) - -While this workflow can be done manually, with a human grader providing the scores, it will not scale to the diverse test inputs and frequent design iterations required for generative AI applications. Instead, we use **AI Assisted Evaluation** effectively getting a second AI application (evaluator) to grade the first AI application (chat) - based on a scoring task that we define using a custom evaluator (Prompty). Let's see how this works. - -## Step 1: Understand Metrics - -The chat application generates its response (ANSWER) given a customer input (QUESTION) and support knowledge (CONTEXT) that can include the customer_id and chat_history. We then assess the _quality_ of the ANSWER using 4 metrics, each scored on a scale of 1-5. - -| Metric | What it assesses | -|:--|:--| -| **Coherence** | How well do all sentences in the ANSWER fit together?
Do they sound natural when taken as a whole? | -| **Fluency** | What is the quality of individual sentences in the ANSWER?
Are they well-written and grammatically correct? | -| **Groundedness**| Given support knowledge, does the ANSWER use the information provided by the CONTEXT? | -| **Relevance**| How well does the ANSWER address the main aspects of the QUESTION, based on the CONTEXT? | - -## Step 2: Understand Evaluators - -The "scoring" task could be performed by a human, but this does not scale. Instead, we use AI-assisted evaluation by using one AI application ("evaluator") to grade the other ("chat"). And just like we used a `chat.prompty` to define our chat application, we can design `evaluator.prompty` instances that define the grading application - with a **custom evaluator** for each assessed metric. - -### 2.1 View/Run all evaluators. - -1.

Let's use the time to explore the code and understand the underlying workflow in more detail" - -### 4.1 Explore: Create Response - -1. Open the file `src/api/evaluators/data.jsonl` - - This file contains the suite of test questions, each associated with a specific customer. - - Sample question: _"what is the waterproof rating of the tent I bought?"_ - -1. Take another look at `src/api/evaluate-chat-flow.ipynb` - - Look at Cell 3, beginning `def create_response_data(df):` - - For each question in the file, the `get_response` function (from our chat application) is invoked to generate the response and associated context - - The {question, context, response} triples are then written to the `results.jsonl` file. - -### 4.2 Explore: Evaluate Response - -1. Take another look at `src/api/evaluate-chat-flow.ipynb` - - Look a cell 4, beginning `def evaluate():` - - **Observe**: It loads the results file from the previous step - - **Observe**: For each result in file, it extracts the "triple" - - **Observe**: For each triple, it executes the 4 evaluator Promptys - - **Observe**: It writes the scores to an `evaluated_results.jsonl` file - -### 4.3 Explore: Create Summary - -1. When notebook execution completes, look in the `src/api/evaluators` folder: - - You see: **Chat Responses** in `result.jsonl` - - You see: **Evaluated Results** in `result_evaluated.jsonl` (scores at end of each line) - - You see: **Evaluation Summary** computed from `eval_results.jsonl` (complete data.) - -1. Scroll to the bottom of the notebook to view the results cell: - - Click the `View as scrollable element` link to redisplay output - - Scroll to the bottom of redisplayed cell to view scores table - - You should see something like the table below - we reformatted it manually for clarity. - -![Eval](./../img/tabular-eval.png) - -### 4.4 Understand: Eval Results - -The figure shows you what that tabulated data looks like in the notebook results. Ignore the formatting for now, and let's look at what this tells us: - -1. You see 12 rows of data - corresponding to 12 test inputs (in `data.jsonl`) -1. You see 4 metrics from custom evaluators - `groundedness`,`fluency`,`coherence`,`relevance` -1. Each metric records a score - between `1` and `5` - -Let's try to put the scores in context of the responses we see. Try these exercises: - -1. Pick a row above that has a `groundedness` of 5. - - View the related row in the `result_evaluation.jsonl` file - - Observe related answer and context in file - _was the answer grounded in the context?_ -1. Pick a row that has a `groundedness` of 1. - - View the related row in the `result_evaluation.jsonl` file - - Observe related answer and context in file - _was THIS answer grounded in the context?_ - -As one example, we can see that the first response in the visualized results (`row 0`) had a groundedness of 5, while the third row from the bottom (`row 9`) had a groundedness of 1. You might find that in the first case the answers provided matched the data context. While in the second case, the answers may quote specific context but did not actually reflect correct usage. - -!!! note "Explore the data in more detail on your own.

After getting acceptable results, it's time to deploy the protoype to production. **But how can we go from Prompty prototype to hosted API endpoint?** Let's build a FastAPI app and serve it with Azure Container Apps. - -## Building FastAPI Apps - -[FastAPI](https://fastapi.tiangolo.com/) is a modern, high-performance web framework for building and serving APIs using Python code. With FastAPI you get a default application server (that can listen on a specified port) that can be configured with various paths (API routes) by defining functions that should be called in response to invocations on those endpoints. - -- You can run the FASTAPI server _locally_ to get a development server with hot reload.

The App Architecture - -Implementing this design pattern requires these architectural components: - - - an **information retrieval** service (data indexing, similarity search, semantic ranking) - - a **database** service for storing other data (customer orders) - - a **model deployments** capability (for chat, embeddings - and AI-assisted evaluation) - - a **copilot hosting** capability (for real-world access to deployed endpoint) - -The corresponding Azure AI application architecture for the Contoso Chat retail copilot is shown below. The copilot is deployed to Azure Container Apps, providing a hosted API endpoint for client integration. The copilot processes incoming requests with the help of: - - - **Azure OpenAI Services** - provides model deployments for chat and text embeddings - - **Azure CosmosDB** - stores the customer order data (JSON) in a noSQL database - - **Azure AI Search** - indexes the product catalog with search-retrieval capability. - -![ACA Architecture](./img/aca-architecture.png) - -The copilot _orchestrates_ the steps of the RAG workflow using **Prompty** assets (configured with required Azure OpenAI models) executed in a Prompty runtime (Python). It supports multi-turn conversations and responsible AI practices to meet response quality and safety requirements. - -## 4. The App Lifecycle - -Building generative AI applications requires an iterative process of refinement from _prompt_ to _production_. The application lifecycle (GenAIOps) is best illustrated by the three stages shown: - -1. **Ideation** - involves building the initial prototype, validating it manually with a test prompt. -2. **Evaluation** - involves assessing it for quality and safety with large, diverse test datasets. -3. **Operationalization** - involves deploying it for real-world usage & monitoring it for insights. - -![GenAIOps](./img/gen-ai-ops.png) - -In our workshop, you willl see the development workflow organized into sections that mimic this lifecycle - giving you a more intuitive sense for how you can iteratively go from promt to production, code-first, with Azure AI. - -## 5.
