This documentation helps a user set up an OAuth-protected AWS Function to connect to a GPT Action, and to a sample application. This example uses AWS SAM (Serverless Application Model) in this example to set-up the AWS stack.\n\n### Value + Example Business Use Cases\n\n**Value**: Users can now leverage ChatGPT's capabilities to connect to an AWS Function. This enables you to connect to any services in AWS and run code/applications on this. This can in a few ways:\n\n- Access 3rd party services such as AWS Redshift, AWS DynamoDB, AWS S3 and even more!\n- Allows pre-processing text responses from an API (overcoming context limits, adding context or metadata as examples).\n- Enables to return files instead of retrieving text from 3rd party APIs. This can be useful to surface CSV files for Data Analysis, or bring back an PDF file and ChatGPT will treat it like an upload. \n\n\n**Example Use Cases**: \n- A user needs to look up data in Redshift, but needs a middleware app between ChatGPT and Redshift to return files (data analysis data exactitude as well as large number of data)\n- A user has built several steps in an AWS function, and needs to be able to kick off that process using ChatGPT.\n\n## Application information & prerequisites\n\nWe will leverage AWS Lambda services to create a middleware function. You can get familiar with this stack by visiting the following links: \n\n- Lambda Website: https://aws.amazon.com/lambda/\n- Lambda Documentation: https://docs.aws.amazon.com/lambda/\n- AWS SAM docs: https://docs.aws.amazon.com/serverless-application-model/\n\n### Prerequisites\n\nBefore you get started, make sure you have an AWS Console with access to create: Lambda Function, S3 Buckets, Application Stack, Cognito User Pool, Cognito User Pool App Clients, API Gateway, Lambda roles, CloudFormation stacks (this feels like a lot but creating those services is automated!).\n\n## Create AWS Lambda Function\n\nTo create an AWS Function you can use AWS SAM. An example of a SAM Template can be found [here](https://github.com/pap-openai/redshift-middleware/blob/main/template.yaml) [0].\n\nThis template includes:\n- A User Pool & User Pool Client, used for OAuth\n- A Cognito Authorizer that ensure the function can only be called by authenticated users\n- Mapping the Lambda function to an existing VPC (useful to connect to other AWS services)\n- Has parameters that can be set-up dynamically (e.g: credentials/variables)\n- An API Gateway that maps HTTP routes to the functions\n\nThis code is purely informational to help you get started and doesn't require pre-existing AWS resources. We recommend to map existing user pools if you have any instead of creating new ones, as well as setting up your Lambda in a VPC that has access to other AWS Resources (if you need to leverage those). You can see an example of a set-up like this in the [RedShift cookbook](https://cookbook.openai.com/examples/chatgpt/gpt_actions_library/gpt_middleware_aws_function).\n\nThe Cognito Authorizer is key to make sure your function can only be called/accessed by authenticated users so make sure to set this up correctly with your environment."}

This cookbook shows you how to create the Cognito Pool from scratch using username/password, though, we recommend to set-up Cognito based on your needs (for example by plugging your own IDP into Cognito).\n\nAdditionally, the function is not connected to any other services, which is the advantage of being able to communicate to an AWS Lambda function in a safe way. You can therefore tweak the code and AWS SAM template to fit your need. An example of a more complex function is Redshift, that follows those steps to create the function and authentication but has a different code/deployment."}

Before you proceed, make sure to first familiarize yourself with the following information: \n- [Introduction to GPT Actions](https://platform.openai.com/docs/actions)\n- [Introduction to GPT Actions Library](https://platform.openai.com/docs/actions/actions-library)\n- [Example of Building a GPT Action from Scratch](https://platform.openai.com/docs/actions/getting-started)\n\nThis GPT Action provides an overview of how to connect to Google Gmail, Google\u2019s Private & Secure Email for Personal or Business. This Action is connected to the Google Gmail APIs that can read, send, list, and draft emails in the authorized account. \n\n### Value + Example Business Use Cases\n\n**Value**: The Gmail GPT will serve as a powerful tool to streamline communication processes, improve customer engagement, and optimize resource allocation.\n\n**Example Use Cases**: \n- Manage internal communications by summarizing lengthy emails and drafting responses based on previous email threads.\n- Support agents can provide customers with instant responses adhering to a company\u2019s communication guidelines, tone, and style.\n- Reference other GPTs , such as a data analsys GPT, and then ask for a draft/send of the consolidated analysis through email communication.\n\n## Application Information\n\n### Application Key Links\n\nCheck out these links from the application before you get started:\n- Application Website: https://mail.google.com/mail/u/0/#inbox\n- Application API Documentation: https://developers.google.com/gmail/api/guides\n\n### Application Prerequisites\n\nBefore you get started, make sure you\u2019ve a Google Cloud account and that the Gmail API is enabled:\n- Set up a Google Cloud project\n- Enable Gmail API from Google API Library\n- If application\u2019s  \u201cPublishing Status\u201d is \u201cTesting\u201d, ensure users are added to your application\n\n## ChatGPT Steps\n\n### Custom GPT Instructions \n\nOnce you've created a Custom GPT, copy the text below in the Instructions panel. Have questions? Check out [Getting Started Example](https://platform.openai.com/docs/actions/getting-started) to see how this step works in more detail."}

This GPT can assist with productivity by summarizing emails/threads, identifying next steps/follow-ups, drafting or sending pre-written responses, and programmatically interacting with third-party tools (e.g., Notion to-dos, Slack channel summaries, data extraction for responses). This GPT has full scope access to the GMAIL OAuth 2.0 API, capable of reading, composing, sending, and permanently deleting emails from Gmail.\n\n**Instructions**\n- Always conclude an email by signing off with logged in user's name, unless otherwise stated.\n- Verify that the email data is correctly encoded in the required format (e.g., base64 for the message body).\n- Email Encoding Process: 1\\ Construct the email message in RFC 2822 format. 2\\ Base64 encode the email message. 3\\Send the encoded message using the API.\n- If not specified, sign all emails with the user name.\n- API Usage: After answering the user's question, do not call the Google API again until another question is asked.\n- All emails created, draft or sent, should be in plain text.\n- Ensure that the email format is clean and is formatted as if someone sent the email from their own inbox. Once a draft is created or email sent, display a message to the user confirming that the draft is ready or the email is sent.\n- Check that the \"to\" email address is valid and in the correct format. It should be in the format \"recipient@example.com\". \n- Only provide summaries of existing emails; do not fabricate email content.\n- Professionalism: Behave professionally, providing clear and concise responses.\n- Clarification: Ask for clarification when needed to ensure accuracy and completeness in fulfilling user requests.\n- Privacy and Security: Respect user privacy and handle all data securely.\n\n```\n\n### OpenAPI Schema \n\nOnce you've created a Custom GPT, copy the text below in the Actions panel.

Enter in the information below. \n\n- **Client ID**: use Client ID from steps above \n- **Client Secret**: use Client Secret from steps above\n- **Authorization URL**: https://accounts.google.com/o/oauth2/auth\n- **Token URL**: https://oauth2.googleapis.com/token \n- **Scope**: https://mail.google.com/\n- **Token**: Default (POST)\n\n### Post-Action Steps\n\nOnce you've set up authentication in ChatGPT, follow the steps below in the application to finalize the Action. \n\n- Copy the callback URL from the GPT Action\n- In the \u201cAuthorized redirect URIs\u201d (see screenshot above), add your callback URL \n\n\n### FAQ & Troubleshooting\n\n- *Callback URL Error:* If you get a callback URL error in ChatGPT, pay close attention to the screenshot above. You need to add the callback URL directly into GCP for the action to authenticate correctly\n- *Schema calls the wrong project or dataset:* If ChatGPT calls the wrong project or dataset, consider updating your instructions to make it more explicit either (a) which project / dataset should be called or (b) to require the user provide those exact details before it runs the query\n\n*Are there integrations that you\u2019d like us to prioritize? Are there errors in our integrations? File a PR or issue in our github, and we\u2019ll take a look.*"}

Before you proceed, make sure to first familiarize yourself with the following information:\n- [Introduction to GPT Actions](https://platform.openai.com/docs/actions)\n- [Introduction to GPT Actions Library](https://platform.openai.com/docs/actions/actions-library)\n- [Example of Building a GPT Action from Scratch](https://platform.openai.com/docs/actions/getting-started)\n\nThis particular GPT Action provides an overview of how to build an **Google Cloud Function**, Google's cloud-based function builder. This documentation helps a user set up an OAuth-protected Google Cloud Function to connect to a GPT Action, and to a sample application.\n\n### Value + Example Business Use Cases\n\n**Value**: Users can now leverage ChatGPT's natural language capability to connect directly to Google Cloud Function. This can in a few ways:\n\n- 100k character limit in GPT Actions: users can use the middleware to pre-process the text response from an API. For example, you can use OpenAI\u2019s API in the middleware to summarize the text before sending it back to ChatGPT.\n- Typically for actions, users are relying on the SaaS API to return text. You can convert the response for the vendor API into easily digestible text, and it can handle different data types such as structured and unstructured data.\n- It can return files instead of just text. This can be useful to surface CSV files for Data Analysis, or bring back an PDF file and ChatGPT will treat it like an upload.\n\n\n**Example Use Cases**:\n- A user needs to look up query Google Cloud SQL, but needs a middleware app between ChatGPT and Google Cloud SQL\n- A user has built several steps in a row in a Google Cloud function, and needs to be able to kick off that process using ChatGPT\n\n## Application Information\n\n### Application Key Links\n\nCheck out these links from the application before you get started:\n- Application Website: https://cloud.google.com/functions/docs\n- Application API Documentation: https://cloud.google.com/functions/docs/writing/write-http-functions\n\n### Application Prerequisites\n\nBefore you get started, make sure you go through the following steps in your application environment:\n- Google Cloud Console with access to create Google Cloud Functions and Google Cloud APIs (you will need this to set up the OAuth Client)\n\n## Application Setup\n\n### Installing the app\n\nThere are 3 options to create and deploy the Google Cloud Functions\n\n*   IDE - create using your favorite IDE, e.g. VS Code\n*   Google Cloud Console - create using your browser\n*   Google Cloud CLI (gcloud) - create through command line\n\nYou can read up on the supported runtimes [here](https://cloud.google.com/functions/docs/concepts/execution-environment)\n\n#### Option 1: Use IDE (VSCode)\n\nSee Google's documentation [here](https://cloud.google.com/functions/docs/create-deploy-ide) for how to deploy using VSCode. If you have familiarity with this approach, feel free to use it.\n\n\n#### Option 2: Directly in Google Cloud Console\n\nSee the documentation [here](https://cloud.google.com/functions/docs/console-quickstart) for how to deploy using the Google Cloud Console. \n\n#### Option 3: Use the Google Cloud CLI (`gcloud`)\n\nSee the documentation [here](https://cloud.google.com/functions/docs/create-deploy-gcloud) for how to deploy using the Google Cloud Console. We\u2019ll walk through an example here step by step."}

Before you proceed, make sure to first familiarize yourself with the following information: \n- [Introduction to GPT Actions](https://platform.openai.com/docs/actions)\n- [Introduction to GPT Actions Library](https://platform.openai.com/docs/actions/actions-library)\n- [Example of Building a GPT Action from Scratch](https://platform.openai.com/docs/actions/getting-started)\n\nThis particular GPT Action provides an overview of how to build an **Azure Function**, MSFT's cloud-based function builder. This documentation helps a user set up an OAuth-protected Azure Function to connect to a GPT Action, and to a sample application. \n\n### Value + Example Business Use Cases\n\n**Value**: Users can now leverage ChatGPT's natural language capability to connect directly to Azure Function. This can in a few ways:\n\n- 100k character limit in GPT Actions: users can use the middleware to pre-process the text response from an API. For example, you can use OpenAI\u2019s API in the middleware to summarize the text before sending it back to ChatGPT.\n- Typically for actions, users are relying on the SaaS API to return text. You can convert the response for the vendor API into easily digestible text, and it can handle different data types such as structured and unstructured data.\n- It can return files instead of just text. This can be useful to surface CSV files for Data Analysis, or bring back an PDF file and ChatGPT will treat it like an upload. \n\n\n**Example Use Cases**: \n- A user needs to look up files in Sharepoint, but needs a middleware app between ChatGPT and Sharepoint\n- A user has built several steps in a row in an Azure function, and needs to be able to kick off that process using ChatGPT\n\n## Application Information\n\n### Application Key Links\n\nCheck out these links from the application before you get started:\n- Application Website: https://learn.microsoft.com/en-us/azure/azure-functions/\n- Application API Documentation: https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference/\n\n### Application Prerequisites\n\nBefore you get started, make sure you go through the following steps in your application environment:\n- Azure Portal with access to create Azure Function Apps and Azure Entra App Registrations\n\n## Application Setup\n\n### Installing the app\n\nYou can read more about languages and deployment options for Azure Functions on the left hand side of the documentation [here](https://learn.microsoft.com/en-us/azure/azure-functions/functions-overview?pivots=programming-language-csharp).\u00a0\n\n#### Option 1: Use VSCode\n\nSee Microsoft\u2019s documentation [here](https://learn.microsoft.com/en-us/azure/azure-functions/functions-develop-vs-code?tabs=node-v4,python-v2,isolated-process\\&pivots=programming-language-javascript) for how to deploy using VSCode. If you have familiarity with this approach, feel free to use it.\u00a0\n\n\n#### Option 2: Directly in Azure Portal\n\nSee the documentation [here](https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-function-app-portal?pivots=programming-language-javascript) for how to deploy using the Azure portal. We\u2019ll walk through an example here step by step.\n\n\n##### Part 1: Create Function\n\n![](../../../images/create_function_app.png)\n\n1. Create an [Azure Function app](https://learn.microsoft.com/en-us/azure/azure-functions/functions-overview?pivots=programming-language-csharp)."}

We\u2019ll walk through an example here step by step.\n\n\n##### Part 1: Create Function\n\n![](../../../images/create_function_app.png)\n\n1. Create an [Azure Function app](https://learn.microsoft.com/en-us/azure/azure-functions/functions-overview?pivots=programming-language-csharp). I used the following settings but you can use anything you are comfortable with. Note that not every language / operating system allows for editing the functions in the console directly - the combination I chose below does. For my walkthrough, I left everything as default and made the selections below. The below settings work out of the box for the SharePoint Node.js solutions [here](https://cookbook.openai.com/examples/chatgpt/gpt_actions_library/gpt_action_sharepoint_doc) and [here](https://cookbook.openai.com/examples/chatgpt/gpt_actions_library/gpt_action_sharepoint_text). \n\n   1. Basics\n\n      1. _Do you want to deploy code or container image?:_\u00a0 **Code**\n\n      2. _Runtime stack:_ **Node.js**\n\n      3. _Operating system:_ **Windows**\n\n   2. Networking\n\n      1. _Enable public access_: **on (need this on to connect to the GPT)**\n\n2. After completing the above, you\u2019ll land on the \u201cDeployments\u201d page. Once the deployment completes (which should only take a few minutes) click on **\u201cGo to Resource\u201d** to go back to the Function App\n\n  > You may get an error the first time you attempt this, click create again and it will likely work. \n\n##### Part 2: Set up Auth\n\n3. On the left-hand side menu of the Azure Function App, click on **Authentication** under the **Settings** menu.\u00a0\n\n   1. Add identity provider\n\n   2. Select **Microsoft** as identity provider.\u00a0\n\n   3. **Workforce** as tenant type\n\n   4. **Create a new application.** The instructions are fairly similar if you are using an existing application, but it is easier to create a new application as it will have the callback URLs and the API exposed automatically using \u201cEasy Auth\u201d. You can read more about that [**here**](https://learn.microsoft.com/en-us/azure/app-service/overview-authentication-authorization).\n\n   5. Leave all the other settings on this page as the default, but feel free to change based on your internal guidelines.\n\n   6. On the **permissions** tab, click **Add Permission** and add **Files.Read.All** and **Sites.ReadAll**, then **Add.** This allows this application to read files which is important in order to use the Microsoft Graph Search API. If you are not using this for the SharePoint solution [here](https://cookbook.openai.com/examples/chatgpt/gpt_actions_library/gpt_action_sharepoint_doc) and [here](https://cookbook.openai.com/examples/chatgpt/gpt_actions_library/gpt_action_sharepoint_text) you can skip this.\n\n4. Once it is created, **click on the enterprise application you just created** (so, leave the Function App page and land on the Enterprise Application that you just spun up)**.** We are now going to give it one more permission, to execute the Azure Function by impersonating the user logging into the application."}

The development of LLMs has been driven by advances in deep learning and natural language processing. A significant milestone in their evolution was the introduction of the transformer architecture by Ashish Vaswani, Noam Shazeer, Niki Parmar, Jakob Uszkoreit, Llion Jones, Aidan N. Gomez, \u0141ukasz Kaiser, and Illia Polosukhin in 2017. LLMs have significantly advanced the fields of natural language processing (NLP) and understanding, enabling applications such as machine translation, text summarization, and conversational agents.\n\n#### Architecture\n\nLLMs are typically based on transformer architecture, which allows them to process and generate text in a highly parallelized manner. Key components of LLM architecture include:\n\n- **Embeddings:** Input text is converted into a continuous vector space using embedding layers. This step transforms discrete words or subwords into numerical representations that capture semantic relationships.\n\n- **Transformer Blocks:** LLMs consist of multiple stacked transformer blocks. Each block contains self-attention mechanisms and feed-forward neural networks. The self-attention mechanism allows the model to weigh the importance of different words in a context, capturing long-range dependencies and relationships within the text.\n\n- **Attention Mechanisms:** Attention mechanisms enable the model to focus on relevant parts of the input text when generating output. This is crucial for tasks like translation, where the model needs to align source and target language elements accurately.\n\n- **Decoder:** In generative models, a decoder is used to generate text from the encoded representations. The decoder uses masked self-attention to ensure that predictions for each word depend only on previously generated words.\n\n#### Training\n\nTraining LLMs involves pre-training and fine-tuning stages:\n\n- **Pre-training:** During this phase, the model is trained on a large corpus of text data using unsupervised learning objectives, such as predicting masked words or the next word in a sequence. This helps the model learn language patterns, grammar, and context.\n\n- **Fine-tuning:** After pre-training, the model is fine-tuned on specific tasks using supervised learning. This stage involves training the model on labeled datasets to perform tasks like sentiment analysis, question answering, or text classification.\n\n#### Applications\n\nLLMs have a wide range of applications across various domains:\n\n- **Text Generation:** LLMs can generate coherent and contextually relevant text, useful for creative writing, content creation, and dialogue generation in chatbots.\n\n- **Machine Translation:** LLMs power modern translation systems, providing accurate translations between multiple languages by understanding the nuances and context of the source text.\n\n- **Summarization:** LLMs can condense long documents into concise summaries, aiding in information retrieval and reducing the time required to understand large volumes of text.\n\n- **Sentiment Analysis:** LLMs can analyze text to determine the sentiment expressed, valuable for market analysis, customer feedback, and social media monitoring.\n\n- **Conversational Agents:** LLMs enable the development of advanced chatbots and virtual assistants that can understand and respond to user queries naturally and contextually.\n\nOverall, LLMs have transformed the field of NLP, enabling more sophisticated and human-like interactions between machines and users, and continue to evolve with ongoing research and technological advancements. The introduction of the transformer architecture by Vaswani et al. has been instrumental in this transformation, providing a foundation for the development of increasingly powerful language models."}

They were invented by Yann LeCun, L\u00e9on Bottou, Yoshua Bengio, and Patrick Haffner in 1989. CNNs have revolutionized the field of computer vision, enabling advancements in areas such as image classification, object detection, and image segmentation.\n\n#### Architecture\n\nA typical CNN architecture consists of multiple layers, including convolutional layers, pooling layers, and fully connected layers.\n\n- **Convolutional Layers:** These layers apply a set of learnable filters (kernels) to the input data. Each filter convolves across the input data, producing a feature map that detects specific features such as edges, textures, and patterns. The parameters of these filters are learned during training.\n\n- **Pooling Layers:** Also known as subsampling or downsampling layers, pooling layers reduce the spatial dimensions of the feature maps. The most common type is max pooling, which selects the maximum value from each region of the feature map, thereby reducing its size and computation requirements while retaining important features.\n\n- **Fully Connected Layers:** After several convolutional and pooling layers, the output is flattened and fed into one or more fully connected layers, which perform the final classification or regression task. These layers resemble those in traditional neural networks, connecting every neuron in one layer to every neuron in the next.\n\n#### Training\n\nCNNs are trained using backpropagation and gradient descent. During training, the network learns the optimal filter values that minimize the loss function, typically a measure of the difference between the predicted and actual labels. The training process involves adjusting the weights of the filters and the fully connected layers through iterative updates.\n\n#### Applications\n\nCNNs have become the cornerstone of many state-of-the-art systems in computer vision. Some notable applications include:\n\n- **Image Classification:** CNNs can classify images into various categories with high accuracy. They have been used in systems like Google Photos and Facebook's automatic tagging.\n\n- **Object Detection:** CNNs can detect and localize objects within an image, which is essential for tasks like autonomous driving and facial recognition.\n\n- **Medical Image Analysis:** CNNs assist in diagnosing diseases by analyzing medical images such as X-rays, MRIs, and CT scans.\n\n- **Image Segmentation:** CNNs are used to partition an image into meaningful segments, useful in applications such as scene understanding and medical image analysis.\n\nOverall, CNNs have significantly advanced the field of artificial intelligence, particularly in tasks that involve visual data, and continue to be an area of active research and development. The pioneering work of LeCun and his colleagues laid the foundation for these transformative technologies, which have since become integral to modern computer vision systems."}

Jordan and Robert A. Jacobs in 1991. MoE models have been applied in various fields, including natural language processing, computer vision, and speech recognition, to improve accuracy and efficiency.\n\n#### Architecture\n\nA typical MoE architecture consists of several key components:\n\n- **Experts:** These are individual models, each trained to specialize in different parts of the input space or specific aspects of the task. Each expert might be a neural network trained to focus on particular features or patterns within the data.\n\n- **Gating Network:** The gating network is responsible for dynamically selecting which experts should be consulted for a given input. It assigns weights to each expert's output, determining their contribution to the final prediction. The gating network typically uses a softmax function to produce these weights, ensuring they sum to one.\n\n- **Combiner:** The combiner aggregates the outputs from the selected experts, weighted by the gating network. This combination can be a weighted sum or another aggregation method, producing the final output of the MoE model.\n\n#### Training\n\nTraining an MoE model involves two main stages:\n\n- **Expert Training:** Each expert model is trained on a subset of the data or a specific aspect of the task. This training can be done independently, with each expert focusing on maximizing performance within its specialized domain.\n\n- **Gating Network Training:** The gating network is trained to learn the optimal combination of experts for different inputs. It uses the loss from the final combined output to adjust its parameters, learning which experts are most relevant for various parts of the input space.\n\n#### Applications\n\nMoE models have a wide range of applications across different domains:\n\n- **Natural Language Processing:** In tasks like machine translation and language modeling, MoE models can dynamically allocate computational resources, allowing different experts to handle different linguistic features or contexts.\n\n- **Computer Vision:** MoE models can be used for image classification and object detection, where different experts specialize in recognizing specific types of objects or features within images.\n\n- **Speech Recognition:** In speech recognition systems, MoE models can improve accuracy by assigning different experts to handle variations in speech, such as accents, intonations, or background noise.\n\n- **Recommendation Systems:** MoE models can enhance recommendation engines by using different experts to analyze various aspects of user behavior and preferences, providing more personalized recommendations.\n\nOverall, Mixture of Experts models offer a powerful framework for improving the performance and efficiency of machine learning systems. By leveraging specialized experts and dynamically selecting the most relevant ones for each input, MoE models can achieve superior results in a variety of complex tasks. The pioneering work of Jordan and Jacobs laid the foundation for this innovative approach, which continues to evolve and find new applications in modern AI research."}

# Unit test writing using a multi-step prompt

Complex tasks, such as writing unit tests, can benefit from multi-step prompts. In contrast to a single prompt, a multi-step prompt generates text from GPT and then feeds that output text back into subsequent prompts. This can help in cases where you want GPT to reason things out before answering, or brainstorm a plan before executing it.

In this notebook, we use a 3-step prompt to write unit tests in Python using the following steps:

1. **Explain**: Given a Python function, we ask GPT to explain what the function is doing and why.
2. **Plan**: We ask GPT to plan a set of unit tests for the function.
    - If the plan is too short, we ask GPT to elaborate with more ideas for unit tests.
3. **Execute**: Finally, we instruct GPT to write unit tests that cover the planned cases.

The code example illustrates a few embellishments on the chained, multi-step prompt:

- Conditional branching (e.g., asking for elaboration only if the first plan is too short)
- The choice of different models for different steps
- A check that re-runs the function if the output is unsatisfactory (e.g., if the output code cannot be parsed by Python's `ast` module)
- Streaming output so that you can start reading the output before it's fully generated (handy for long, multi-step outputs)

    A good unit test suite should aim to:
    - Test the function's behavior for a wide range of possible inputs
    - Test edge cases that the author may not have foreseen
    - Take advantage of the features of `pytest` to make the tests easy to write and maintain
    - Be easy to read and understand, with clean code and descriptive names
    - Be deterministic, so that the tests always pass or fail in the same way
    
    To help unit test the function above, list diverse scenarios that the function should be able to handle (and under each scenario, include a few examples as sub-bullets).

Make sure to check any code before using it, as GPT makes plenty of mistakes (especially on character-based tasks like this one). For best results, use the most powerful model (GPT-4, as of May 2023).

# How to use the moderation API

**Note:** This guide is designed to complement our Guardrails Cookbook by providing a more focused look at moderation techniques. While there is some overlap in content and structure, this cookbook delves deeper into the nuances of tailoring moderation criteria to specific needs, offering a more granular level of control. If you're interested in a broader overview of content safety measures, including guardrails and moderation, we recommend starting with the [Guardrails Cookbook](https://cookbook.openai.com/examples/how_to_use_guardrails). Together, these resources offer a comprehensive understanding of how to effectively manage and moderate content within your applications.

Moderation, much like guardrails in the physical world, serves as a preventative measure to ensure that your application remains within the bounds of acceptable and safe content. Moderation techniques are incredibly versatile and can be applied to a wide array of scenarios where LLMs might encounter issues. This notebook is designed to offer straightforward examples that can be adapted to suit your specific needs, while also discussing the considerations and trade-offs involved in deciding whether to implement moderation and how to go about it. This notebook will use our [Moderation API](https://platform.openai.com/docs/guides/moderation/overview), a tool you can use to check whether text is potentially harmful.

This notebook will concentrate on:

- **Input Moderation:** Identifying and flagging inappropriate or harmful content before it is processed by your LLM.
- **Output Moderation:** Reviewing and validating the content generated by your LLM before it reaches the end user.
- **Custom Moderation:** Tailoring moderation criteria and rules to suit the specific needs and context of your application, ensuring a personalized and effective content control mechanism.

client = OpenAI()

GPT_MODEL = 'gpt-4o-mini'
```

### 1. Input moderation
Input Moderation focuses on preventing harmful or inappropriate content from reaching the LLM, with common applications including:
- **Content Filtering:** Prevent the spread of harmful content such as hate speech, harassment, explicit material, and misinformation on social media, forums, and content creation platforms.
- **Community Standards Enforcement:** Ensure that user interactions, such as comments, forum posts, and chat messages, adhere to the community guidelines and standards of online platforms, including educational environments, gaming communities, or dating apps.
- **Spam and Fraud Prevention:** Filter out spam, fraudulent content, and misleading information in online forums, comment sections, e-commerce platforms, and customer reviews.

These measures act as preventive controls, operating before or alongside the LLM to alter your application's behavior if specific criteria are met.

#### Embrace async
A common design to minimize latency is to send your moderations asynchronously along with your main LLM call. If your moderation gets triggered you send back a placeholder response, otherwise send back the LLM response. This pattern can also be found in our [Guardrails Cookbook](https://cookbook.openai.com/examples/how_to_use_guardrails). It's important to note that while the async mode is effective in minimizing latency, it can also lead to unnecessary costs. Specifically, you could avoid completion costs if the content is flagged before processing. Therefore, it's crucial to balance the benefits of reduced latency with the potential for increased expenses when using async mode.

We'll use this approach, creating an execute_chat_with_moderation function that will run our LLM's get_chat_response and the check_expression moderation function in parallel, and return the LLM response only if the moderation returns False (not triggered).

#### Workflow:
We will create a workflow that incorporates the Moderation API to check user input for any potentially unsafe content before it is sent to the Language Model (LLM). This ensures that only appropriate content is processed further in the application.

1. Receive an input from the user
2. Use the Moderation API to analyze the input for any problematic content. 
3. **Conditional Processing:** 
- If the input is flagged by the moderation check, handle it accordingly (e.g., reject the input, ask the user to rephrase, etc.).
- If the input is not flagged, pass it to the LLM for further processing.

We will demonstrate this workflow with two example prompts.

Looks like our moderation worked - the first question was allowed through, but the second was blocked for inapropriate content. Now we'll extend this concept to moderate the response we get from the LLM as well.

### 2. Output moderation

Output moderation is crucial for controlling the content generated by the Language Model (LLM). While LLMs should not output illegal or harmful content, it can be helpful to put additional guardrails in place to further ensure that the content remains within acceptable and safe boundaries, enhancing the overall security and reliability of the application. Common types of output moderation include:

- **Content Quality Assurance:** Ensure that generated content, such as articles, product descriptions, and educational materials, is accurate, informative, and free from inappropriate information.
- **Community Standards Compliance:** Maintain a respectful and safe environment in online forums, discussion boards, and gaming communities by filtering out hate speech, harassment, and other harmful content.
- **User Experience Enhancement:** Improve the user experience in chatbots and automated services by providing responses that are polite, relevant, and free from any unsuitable language or content.

In all these scenarios, output moderation plays a crucial role in maintaining the quality and integrity of the content generated by language models, ensuring that it meets the standards and expectations of the platform and its users.

#### Setting moderation thresholds
OpenAI has selected thresholds for moderation categories that balance precision and recall for our use cases, but your use case or tolerance for moderation may be different. Setting this threshold is a common area for optimization - we recommend building an evaluation set and grading the results using a confusion matrix to set the right tolerance for your moderation. The trade-off here is generally:

- More false positives leads to a fractured user experience, where customers get annoyed and the assistant seems less helpful.
- More false negatives can cause lasting harm to your business, as people get the assistant to answer inappropriate questions, or provide inappropriate responses.

For example, on a platform dedicated to creative writing, the moderation threshold for certain sensitive topics might be set higher to allow for greater creative freedom while still providing a safety net to catch content that is clearly beyond the bounds of acceptable expression. The trade-off is that some content that might be considered inappropriate in other contexts is allowed, but this is deemed acceptable given the platform's purpose and audience expectations.

#### Workflow:
We will create a workflow that incorporates the Moderation API to check the LLM response for any potentially unsafe content before it is sent to the Language Model (LLM). This ensures that only appropriate content is displayed to the user.

1. Receive an input from the user
2. Send prompt to LLM and generate a response
3. Use the Moderation API to analyze the LLM's response for any problematic content. 
3. **Conditional Processing:** 
- If the response is flagged by the moderation check, handle it accordingly (e.g., reject the response, show a placeholder message, etc.).
- If the response is not flagged, display it to the user.

We will demonstrate this workflow with the previous two example prompts.

As observed, the first two examples behaved as expected. However, the "interesting example" did not perform as anticipated. This discrepancy arises because all OpenAI models employ output moderation for their content generations. Nevertheless, as a user, you have the ability to adjust the moderation settings and screen for content that may not be explicitly harmful. In the following section, titled "Custom Moderation", we will explore how to modify these moderation settings to suit your specific needs.

### 3. Custom moderation

**Note: This section does not use the Moderation API.**

Custom moderation provides a tailored approach to content filtering, allowing for precise adherence to specific community standards or topics, making it an ideal choice for niche platforms or specialized content. Unlike the general categories covered by the moderation API, custom moderation offers a higher degree of control and requires more effort to set up and maintain. It shares the common goal of ensuring content safety with guardrails, focusing on setting criteria to filter and manage content, whether it's user input or output from language models. Custom moderation can be an alternative or an extension to the moderation API, that uses our completions endpoint. For those interested in exploring guardrails further, a cookbook with examples and guidance is available [here](https://cookbook.openai.com/examples/how_to_use_guardrails).

#### Workflow
We will implement a small example to showcase custom moderation. We will use an extra call to gpt-4o mini to assess messages and decide if they should be moderated or not.

### Conclusion

In conclusion, this notebook has explored the essential role of moderation in applications powered by language models (LLMs). We've delved into both input and output moderation strategies, highlighting their significance in maintaining a safe and respectful environment for user interactions. Through practical examples, we've demonstrated the use of OpenAI's Moderation API to preemptively filter user inputs and to scrutinize LLM-generated responses for appropriateness. The implementation of these moderation techniques is crucial for upholding the integrity of your application and ensuring a positive experience for your users.

As you further develop your application, consider the ongoing refinement of your moderation strategies through custom moderations. This may involve tailoring moderation criteria to your specific use case or integrating a combination of machine learning models and rule-based systems for a more nuanced analysis of content. Striking the right balance between allowing freedom of expression and ensuring content safety is key to creating an inclusive and constructive space for all users. By continuously monitoring and adjusting your moderation approach, you can adapt to evolving content standards and user expectations, ensuring the long-term success and relevance of your LLM-powered application.

# Retrieval Augmented Generation with a Graph Database

This notebook shows how to use LLMs in combination with [Neo4j](https://neo4j.com/), a graph database, to perform Retrieval Augmented Generation (RAG).

### Why use RAG?

If you want to use LLMs to generate answers based on your own content or knowledge base, instead of providing large context when prompting the model, you can fetch the relevant information in a database and use this information to generate a response. 

This allows you to:
- Reduce hallucinations
- Provide relevant, up to date information to your users
- Leverage your own content/knowledge base

### Why use a graph database?

If you have data where relationships between data points are important and you might want to leverage that, then it might be worth considering graph databases instead of traditional relational databases.

Graph databases are good to address the following:
- Navigating deep hierarchies
- Finding hidden connections between items
- Discovering relationships between items

### Use cases 

Graph databases are particularly relevant for recommendation systems, network relationships or analysing correlation between data points.  

Example use cases for RAG with graph databases include:
- Recommendation chatbot
- AI-augmented CRM 
- Tool to analyse customer behavior with natural language

Depending on your use case, you can assess whether using a graph database makes sense. 

In this notebook, we will build a **product recommendation chatbot**, with a graph database that contains Amazon products data.


## Setup

We will start by installing and importing the relevant libraries.  

Make sure you have your OpenAI account set up and you have your OpenAI API key handy. 


```python
# Optional: run to install the libraries locally if you haven't already 
!pip3 install langchain
!pip3 install openai
!pip3 install neo4j
```


```python
import os
import json 
import pandas as pd
```


```python
# Optional: run to load environment variables from a .env file.
# This is not required if you have exported your env variables in another way or if you set it manually
!pip3 install python-dotenv
from dotenv import load_dotenv
load_dotenv()

# Set the OpenAI API key env variable manually
# os.environ["OPENAI_API_KEY"] = "<your_api_key>"

# print(os.environ["OPENAI_API_KEY"])
```

## Dataset

We will use a dataset that was created from a relational database and converted to a json format, creating relationships between entities with the completions API.

We will then load this data into the graph db to be able to query it.

### Loading dataset


```python
# Loading a json dataset from a file
file_path = 'data/amazon_product_kg.json'

with open(file_path, 'r') as file:
    jsonData = json.load(file)
```


```python
df =  pd.read_json(file_path)
df.head()
```

## Querying the database

### Creating vector indexes

In order to efficiently search our database for terms closely related to user queries, we need to use embeddings. To do this, we will create vector indexes on each type of property.

We will be using the OpenAIEmbeddings Langchain utility. It's important to note that Langchain adds a pre-processing step, so the embeddings will slightly differ from those generated directly with the OpenAI embeddings API.


```python
from langchain.vectorstores.neo4j_vector import Neo4jVector
from langchain.embeddings.openai import OpenAIEmbeddings
embeddings_model = "text-embedding-3-small"
```

    "I'm sorry, but I don't have any information to help you find curtains."



### Extracting entities from the prompt

However, there is little added value here compared to just writing the Cypher queries ourselves, and it is prone to error.

Indeed, asking an LLM to generate a Cypher query directly might result in the wrong parameters being used, whether it's the entity type or the relationship type, as is the case above.

We will instead use LLMs to decide what to search for, and then generate the corresponding Cypher queries using templates.

For this purpose, we will instruct our model to find relevant entities in the user prompt that can be used to query our database.

### Extracting entities from the prompt

However, there is little added value here compared to just writing the Cypher queries ourselves, and it is prone to error.

Indeed, asking an LLM to generate a Cypher query directly might result in the wrong parameters being used, whether it's the entity type or the relationship type, as is the case above.

We will instead use LLMs to decide what to search for, and then generate the corresponding Cypher queries using templates.

For this purpose, we will instruct our model to find relevant entities in the user prompt that can be used to query our database.


```python
entity_types = {
    "product": "Item detailed type, for example 'high waist pants', 'outdoor plant pot', 'chef kitchen knife'",
    "category": "Item category, for example 'home decoration', 'women clothing', 'office supply'",
    "characteristic": "if present, item characteristics, for example 'waterproof', 'adhesive', 'easy to use'",
    "measurement": "if present, dimensions of the item", 
    "brand": "if present, brand of the item",
    "color": "if present, color of the item",
    "age_group": "target age group for the product, one of 'babies', 'children', 'teenagers', 'adults'. If suitable for multiple age groups, pick the oldest (latter in the list)."
}

relation_types = {
    "hasCategory": "item is of this category",
    "hasCharacteristic": "item has this characteristic",
    "hasMeasurement": "item is of this measurement",
    "hasBrand": "item is of this brand",
    "hasColor": "item is of this color", 
    "isFor": "item is for this age_group"
 }

entity_relationship_match = {
    "category": "hasCategory",
    "characteristic": "hasCharacteristic",
    "measurement": "hasMeasurement", 
    "brand": "hasBrand",
    "color": "hasColor",
    "age_group": "isFor"
}
```

```python
system_prompt = f'''
    You are a helpful agent designed to fetch information from a graph database. 
    
    The graph database links products to the following entity types:
    {json.dumps(entity_types)}
    
    Each link has one of the following relationships:
    {json.dumps(relation_types)}

    Depending on the user prompt, determine if it possible to answer with the graph database.
        
    The graph database can match products with multiple relationships to several entities.
    
    Example user input:
    "Which blue clothing items are suitable for adults?"
    
    There are three relationships to analyse:
    1. The mention of the blue color means we will search for a color similar to "blue"
    2. The mention of the clothing items means we will search for a category similar to "clothing"
    3. The mention of adults means we will search for an age_group similar to "adults"
    
    
    Return a json object following the following rules:
    For each relationship to analyse, add a key value pair with the key being an exact match for one of the entity types provided, and the value being the value relevant to the user query.
    
    For the example provided, the expected output would be:
    {{
        "color": "blue",
        "category": "clothing",
        "age_group": "adults"
    }}
    
    If there are no relevant entities in the user prompt, return an empty json object.

### Generating queries

Now that we know what to look for, we can generate the corresponding Cypher queries to query our database. 

However, the entities extracted might not be an exact match with the data we have, so we will use the GDS cosine similarity function to return products that have relationships with entities similar to what the user is asking.


```python
def create_embedding(text):
    result = client.embeddings.create(model=embeddings_model, input=text)
    return result.data[0].embedding
```


```python
# The threshold defines how closely related words should be. Adjust the threshold to return more or less results
def create_query(text, threshold=0.81):
    query_data = json.loads(text)
    # Creating embeddings
    embeddings_data = []
    for key, val in query_data.items():
        if key != 'product':
            embeddings_data.append(f"${key}Embedding AS {key}Embedding")
    query = "WITH " + ",\n".join(e for e in embeddings_data)
    # Matching products to each entity
    query += "\nMATCH (p:Product)\nMATCH "
    match_data = []
    for key, val in query_data.items():
        if key != 'product':
            relationship = entity_relationship_match[key]
            match_data.append(f"(p)-[:{relationship}]->({key}Var:{key})")
    query += ",\n".join(e for e in match_data)
    similarity_data = []
    for key, val in query_data.items():
        if key != 'product':
            similarity_data.append(f"gds.similarity.cosine({key}Var.embedding, ${key}Embedding) > {threshold}")
    query += "\nWHERE "

### Finding similar items 

We can then leverage the graph db to find similar products based on common characteristics.

This is where the use of a graph db really comes into play.

For example, we can look for products that are the same category and have another characteristic in common, or find products that have relationships to the same entities. 

This criteria is arbitrary and completely depends on what is the most relevant in relation to your use case.

### Finding similar items 

We can then leverage the graph db to find similar products based on common characteristics.

This is where the use of a graph db really comes into play.

For example, we can look for products that are the same category and have another characteristic in common, or find products that have relationships to the same entities. 

This criteria is arbitrary and completely depends on what is the most relevant in relation to your use case.


```python
# Adjust the relationships_threshold to return products that have more or less relationships in common
def query_similar_items(product_id, relationships_threshold = 3):
    
    similar_items = []
        
    # Fetching items in the same category with at least 1 other entity in common
    query_category = '''
            MATCH (p:Product {id: $product_id})-[:hasCategory]->(c:category)
            MATCH (p)-->(entity)
            WHERE NOT entity:category
            MATCH (n:Product)-[:hasCategory]->(c)
            MATCH (n)-->(commonEntity)
            WHERE commonEntity = entity AND p.id <> n.id
            RETURN DISTINCT n;
        '''
    

    result_category = graph.query(query_category, params={"product_id": int(product_id)})
    #print(f"{len(result_category)} similar items of the same category were found.")
          
    # Fetching items with at least n (= relationships_threshold) entities in common
    query_common_entities = '''
        MATCH (p:Product {id: $product_id})-->(entity),
            (n:Product)-->(entity)
            WHERE p.id <> n.id
            WITH n, COUNT(DISTINCT entity) AS commonEntities
            WHERE commonEntities >= $threshold
            RETURN n;
        '''
    result_common_entities = graph.query(query_common_entities, params={"product_id": int(product_id), "threshold": relationships_threshold})
    #print(f"{len(result_common_entities)} items with at least {relationships_threshold} things in common were found.")

    for i in result_category:
        similar_items.append({
            "id": i['n']['id'],
            "name": i['n']['name']
        })
            
    for i in result_common_entities:
        result_id = i['n']['id']
        if not any(item['id'] == result_id for item in similar_items):
            similar_items.append({
                "id": result_id,
                "name": i['n']['name']
            })
    return similar_items

## Final result

Now that we have all the pieces working, we will stitch everything together. 

We can also add a fallback option to do a product name/title similarity search if we can't find relevant entities in the user prompt.

We will explore 2 options, one with a Langchain agent for a conversational experience, and one that is more deterministic based on code only. 

Depending on your use case, you might choose one or the other option and tailor it to your needs.

We need to define exactly how the agent should behave, and give it access to our query and similarity search tools.

{tools}

Use the following format:

Question: the input prompt from the user
Thought: you should always think about what to do
Action: the action to take (refer to the rules below)
Action Input: the input to the action
Observation: the result of the action
... (this Thought/Action/Action Input/Observation can repeat N times)
Thought: I now know the final answer
Final Answer: the final answer to the original input question

Rules to follow:

1. Start by using the Query tool with the prompt as parameter. If you found results, stop here.
2. If the result is an empty array, use the similarity search tool with the full initial user prompt. If you found results, stop here.
3. If you cannot still cannot find the answer with this, probe the user to provide more context on the type of product they are looking for. 

Keep in mind that we can use entities of the following types to search for products:

{entity_types}.

3. Repeat Step 1 and 2. If you found results, stop here.

4. If you cannot find the final answer, say that you cannot help with the question.

Never return results if you did not find any results in the array returned by the query tool or the similarity search tool.

If you didn't find any result, reply: "Sorry, I didn't find any suitable products."

If you found results from the database, this is your final answer, reply to the user by announcing the number of results and returning results in this format (each new result should be on a new line):

name_of_the_product (id_of_the_product)"

Only use exact names and ids of the products returned as results when providing your final answer.

prompt_template = '''Your goal is to find a product in the database that best matches the user prompt.
You have access to these tools:

{tools}

Use the following format:

Question: the input prompt from the user
Thought: you should always think about what to do
Action: the action to take (refer to the rules below)
Action Input: the input to the action
Observation: the result of the action
... (this Thought/Action/Action Input/Observation can repeat N times)
Thought: I now know the final answer
Final Answer: the final answer to the original input question

Rules to follow:

1. Start by using the Query tool with the prompt as parameter. If you found results, stop here.
2. If the result is an empty array, use the similarity search tool with the full initial user prompt. If you found results, stop here.
3. If you cannot still cannot find the answer with this, probe the user to provide more context on the type of product they are looking for. 

Keep in mind that we can use entities of the following types to search for products:

{entity_types}.

3. Repeat Step 1 and 2. If you found results, stop here.

4. If you cannot find the final answer, say that you cannot help with the question.

Never return results if you did not find any results in the array returned by the query tool or the similarity search tool.

If you didn't find any result, reply: "Sorry, I didn't find any suitable products."

If you found results from the database, this is your final answer, reply to the user by announcing the number of results and returning results in this format (each new result should be on a new line):

name_of_the_product (id_of_the_product)"

Only use exact names and ids of the products returned as results when providing your final answer.

### Building a code-only experience

As our experiments show, using an agent for this type of task might not be the best option.

Indeed, the agent seems to retrieve results from the tools, but comes up with made-up responses. 

For this specific use case, if the conversational aspect is less relevant, we can actually create a function that will call our previously-defined tasks and provide an answer.

### Building a code-only experience

As our experiments show, using an agent for this type of task might not be the best option.

Indeed, the agent seems to retrieve results from the tools, but comes up with made-up responses. 

For this specific use case, if the conversational aspect is less relevant, we can actually create a function that will call our previously-defined tasks and provide an answer.


```python
import logging

def answer(prompt, similar_items_limit=10):
    print(f'Prompt: "{prompt}"\n')
    params = define_query(prompt)
    print(params)
    result = query_db(params)
    print(f"Found {len(result)} matches with Query function.\n")
    if len(result) == 0:
        result = similarity_search(prompt)
        print(f"Found {len(result)} matches with Similarity search function.\n")
        if len(result) == 0:
            return "I'm sorry, I did not find a match. Please try again with a little bit more details."
    print(f"I have found {len(result)} matching items:\n")
    similar_items = []
    for r in result:
        similar_items.extend(query_similar_items(r['id']))
        print(f"{r['name']} ({r['id']})")
    print("\n")
    if len(similar_items) > 0:
        print("Similar items that might interest you:\n")
        for i in similar_items[:similar_items_limit]:
            print(f"{i['name']} ({i['id']})")
    print("\n\n\n")
    return result
```


```python
prompt1 = "I'm looking for food items to gift to someone for Christmas. Ideally chocolate."

prompt2 = "Help me find women clothes for my wife. She likes blue."
answer(prompt2)

## Conclusion

### User experience

When the primary objective is to extract specific information from our database, Large Language Models (LLMs) can significantly enhance our querying capabilities.

However, it's crucial to base much of this process on robust code logic to ensure a foolproof user experience.

For crafting a genuinely conversational chatbot, further exploration in prompt engineering is necessary, possibly incorporating few-shot examples. This approach helps mitigate the risk of generating inaccurate or misleading information and ensures more precise responses.

Ultimately, the design choice depends on the desired user experience. For instance, if the aim is to create a visual recommendation system, the importance of a conversational interface is less relevant.

### Working with a knowledge graph 

Retrieving content from a knowledge graph adds complexity but can be useful if you want to leverage connections between items. 

The querying part of this notebook would work on a relational database as well, the knowledge graph comes in handy when we want to couple the results with similar items that the graph is surfacing. 

Considering the added complexity, make sure using a knowledge graph is the best option for your use case.
If it is the case, feel free to refine what this cookbook presents to match your needs and perform even better!

# Data preparation and analysis for chat model fine-tuning

This notebook serves as a tool to preprocess and analyze the chat dataset used for fine-tuning a chat model. 
It checks for format errors, provides basic statistics, and estimates token counts for fine-tuning costs.
The method shown here corresponds to the [current fine-tuning method](https://platform.openai.com/docs/guides/fine-tuning) for gpt-3.5-turbo.
See [legacy fine-tuning](https://platform.openai.com/docs/guides/legacy-fine-tuning) for models like babbage-002 and davinci-002.


```python
import json
import tiktoken # for token counting
import numpy as np
from collections import defaultdict
```

## Data loading

We first load the chat dataset from an [example JSONL file](https://github.com/openai/openai-cookbook/blob/main/examples/data/toy_chat_fine_tuning.jsonl).


```python
data_path = "data/toy_chat_fine_tuning.jsonl"

# Load the dataset
with open(data_path, 'r', encoding='utf-8') as f:
    dataset = [json.loads(line) for line in f]

# Initial dataset stats
print("Num examples:", len(dataset))
print("First example:")
for message in dataset[0]["messages"]:
    print(message)
```

    Num examples: 5
    First example:
    {'role': 'system', 'content': 'You are a happy assistant that puts a positive spin on everything.'}
    {'role': 'user', 'content': 'I fell off my bike today.'}
    {'role': 'assistant', 'content': "It's great that you're getting exercise outdoors!"}


## Format validation

We can perform a variety of error checks to validate that each conversation in the dataset adheres to the format expected by the fine-tuning API. Errors are categorized based on their nature for easier debugging.

1. **Data Type Check**: Checks whether each entry in the dataset is a dictionary (`dict`). Error type: `data_type`.
2. **Presence of Message List**: Checks if a `messages` list is present in each entry. Error type: `missing_messages_list`.
3. **Message Keys Check**: Validates that each message in the `messages` list contains the keys `role` and `content`. Error type: `message_missing_key`.
4. **Unrecognized Keys in Messages**: Logs if a message has keys other than `role`, `content`, `weight`, `function_call`, and `name`. Error type: `message_unrecognized_key`.
5. **Role Validation**: Ensures the `role` is one of "system", "user", or "assistant". Error type: `unrecognized_role`.
6. **Content Validation**: Verifies that `content` has textual data and is a string. Error type: `missing_content`.
7. **Assistant Message Presence**: Checks that each conversation has at least one message from the assistant. Error type: `example_missing_assistant_message`.

The code below performs these checks, and outputs counts for each type of error found are printed. This is useful for debugging and ensuring the dataset is ready for the next steps.

## Format validation

We can perform a variety of error checks to validate that each conversation in the dataset adheres to the format expected by the fine-tuning API. Errors are categorized based on their nature for easier debugging.

1. **Data Type Check**: Checks whether each entry in the dataset is a dictionary (`dict`). Error type: `data_type`.
2. **Presence of Message List**: Checks if a `messages` list is present in each entry. Error type: `missing_messages_list`.
3. **Message Keys Check**: Validates that each message in the `messages` list contains the keys `role` and `content`. Error type: `message_missing_key`.
4. **Unrecognized Keys in Messages**: Logs if a message has keys other than `role`, `content`, `weight`, `function_call`, and `name`. Error type: `message_unrecognized_key`.
5. **Role Validation**: Ensures the `role` is one of "system", "user", or "assistant". Error type: `unrecognized_role`.
6. **Content Validation**: Verifies that `content` has textual data and is a string. Error type: `missing_content`.
7. **Assistant Message Presence**: Checks that each conversation has at least one message from the assistant. Error type: `example_missing_assistant_message`.

The code below performs these checks, and outputs counts for each type of error found are printed. This is useful for debugging and ensuring the dataset is ready for the next steps.



```python
# Format error checks
format_errors = defaultdict(int)

for ex in dataset:
    if not isinstance(ex, dict):
        format_errors["data_type"] += 1
        continue
        
    messages = ex.get("messages", None)
    if not messages:
        format_errors["missing_messages_list"] += 1
        continue
        
    for message in messages:
        if "role" not in message or "content" not in message:
            format_errors["message_missing_key"] += 1
        
        if any(k not in ("role", "content", "name", "function_call", "weight") for k in message):
            format_errors["message_unrecognized_key"] += 1
        
        if message.get("role", None) not in ("system", "user", "assistant", "function"):
            format_errors["unrecognized_role"] += 1
            
        content = message.get("content", None)
        function_call = message.get("function_call", None)
        
        if (not content and not function_call) or not isinstance(content, str):
            format_errors["missing_content"] += 1
    
    if not any(message.get("role", None) == "assistant" for message in messages):
        format_errors["example_missing_assistant_message"] += 1

if format_errors:
    print("Found errors:")
    for k, v in format_errors.items():
        print(f"{k}: {v}")
else:
    print("No errors found")
```

    No errors found

## Data Warnings and Token Counts 

With some lightweight analysis we can identify potential issues in the dataset, like missing messages, and provide statistical insights into message and token counts.

1. **Missing System/User Messages**: Counts the number of conversations missing a "system" or "user" message. Such messages are critical for defining the assistant's behavior and initiating the conversation.
2. **Number of Messages Per Example**: Summarizes the distribution of the number of messages in each conversation, providing insight into dialogue complexity.
3. **Total Tokens Per Example**: Calculates and summarizes the distribution of the total number of tokens in each conversation. Important for understanding fine-tuning costs.
4. **Tokens in Assistant's Messages**: Calculates the number of tokens in the assistant's messages per conversation and summarizes this distribution. Useful for understanding the assistant's verbosity.
5. **Token Limit Warnings**: Checks if any examples exceed the maximum token limit (16,385 tokens), as such examples will be truncated during fine-tuning, potentially resulting in data loss.

# Clustering for Transaction Classification

This notebook covers use cases where your data is unlabelled but has features that can be used to cluster them into meaningful categories. The challenge with clustering is making the features that make those clusters stand out human-readable, and that is where we'll look to use GPT-3 to generate meaningful cluster descriptions for us. We can then use these to apply labels to a previously unlabelled dataset.

To feed the model we use embeddings created using the approach displayed in the notebook [Multiclass classification for transactions Notebook](Multiclass_classification_for_transactions.ipynb), applied to the full 359 transactions in the dataset to give us a bigger pool for learning

## Setup


```python
# optional env import
from dotenv import load_dotenv
load_dotenv()
```




    True




```python
# imports
 
from openai import OpenAI
import pandas as pd
import numpy as np
from sklearn.cluster import KMeans
from sklearn.manifold import TSNE
import matplotlib
import matplotlib.pyplot as plt
import os
from ast import literal_eval

client = OpenAI(api_key=os.environ.get("OPENAI_API_KEY", "<your OpenAI API key if not set as env var>"))
COMPLETIONS_MODEL = "gpt-3.5-turbo"

# This path leads to a file with data and precomputed embeddings
embedding_path = "data/library_transactions_with_embeddings_359.csv"

```

## Clustering

We'll reuse the approach from the [Clustering Notebook](Clustering.ipynb), using K-Means to cluster our dataset using the feature embeddings we created previously. We'll then use the Completions endpoint to generate cluster descriptions for us and judge their effectiveness


```python
df = pd.read_csv(embedding_path)
df.head()
```

# Clustering for Transaction Classification

This notebook covers use cases where your data is unlabelled but has features that can be used to cluster them into meaningful categories. The challenge with clustering is making the features that make those clusters stand out human-readable, and that is where we'll look to use GPT-3 to generate meaningful cluster descriptions for us. We can then use these to apply labels to a previously unlabelled dataset.

To feed the model we use embeddings created using the approach displayed in the notebook [Multiclass classification for transactions Notebook](Multiclass_classification_for_transactions.ipynb), applied to the full 359 transactions in the dataset to give us a bigger pool for learning

## Setup


```python
# optional env import
from dotenv import load_dotenv
load_dotenv()
```




    True




```python
# imports
 
from openai import OpenAI
import pandas as pd
import numpy as np
from sklearn.cluster import KMeans
from sklearn.manifold import TSNE
import matplotlib
import matplotlib.pyplot as plt
import os
from ast import literal_eval

client = OpenAI(api_key=os.environ.get("OPENAI_API_KEY", "<your OpenAI API key if not set as env var>"))
COMPLETIONS_MODEL = "gpt-3.5-turbo"

# This path leads to a file with data and precomputed embeddings
embedding_path = "data/library_transactions_with_embeddings_359.csv"

```

## Clustering

We'll reuse the approach from the [Clustering Notebook](Clustering.ipynb), using K-Means to cluster our dataset using the feature embeddings we created previously. We'll then use the Completions endpoint to generate cluster descriptions for us and judge their effectiveness


```python
df = pd.read_csv(embedding_path)
df.head()
```
