Enabling GPT-4 Turbo with Vision

This repository now includes an example of integrating GPT-4 Turbo with Vision with Azure AI Search. This feature enables indexing and searching images and graphs, such as financial documents, in addition to text-based content.

Feature Overview

• Document Handling: Source documents are split into pages and saved as PNG files in blob storage. Each file's name and page number are embedded for reference.
• Data Extraction: Text data is extracted using OCR.
• Data Indexing: Text and image embeddings, generated using Azure AI Vision (Azure AI Vision Embeddings), are indexed in Azure AI Search along with the raw text.
• Search and Response: Searches can be conducted using vectors or hybrid methods. Responses are generated by GPT-4 Turbo with Vision based on the retrieved content.

Getting Started

Prerequisites

• Create a Computer Vision account in Azure Portal first, so that you can agree to the Responsible AI terms for that resource. You can delete that account after agreeing.
• Check that your Azure OpenAI subscription has access to create a GPT-4 Turbo with Vision model.
• Ensure that you can deploy the Azure OpenAI resource group in a region where all required components are available:
  • Azure Open AI models
    • gpt-35-turbo
    • text-embedding-ada-002
    • gpt-4v
  • Azure AI Vision

Setup and Usage

1. Update repository: Pull the latest changes.

2. Enable GPT-4 Turbo with Vision: Set the environment variable with azd env set USE_GPT4V true. This flag is used to deploy necessary components for vision fuctionality and to toggle UI components.

3. Clean old deployments (optional): Run azd down --purge for a fresh setup.

4. Start the application: Execute azd up to build, provision, deploy, and initiate document preparation.

5. Web Application Usage:

   • Access the developer options in the web app and select "Use GPT-4 Turbo with Vision".
   • Sample questions will be updated for testing.
   • Interact with the questions to view responses.
   • The 'Thought Process' tab shows the retrieved data and its processing by GPT-4 Turbo with Vision.
