Learn to build a vector database leveraging Claude and ChatGPT API to enhance data retrieval and user interaction.

Prerequisites

  • Python 3.9 or higher
  • OpenAI API Key and Claude API Key
  • Basic understanding of vector databases and embeddings

What We’re Building

In this tutorial, we will create a vector database using Claude and ChatGPT APIs. This database will store embeddings generated from user inputs, enabling efficient retrieval and classification of information. The end result is a robust system capable of handling semantic searches and augmenting large language models with retrieval-augmented generation (RAG).

The system will allow users to input queries and receive contextually relevant information by comparing the embeddings of their queries against those stored in the database. This is particularly useful in applications like chatbots, personalized recommendations, and advanced AI tools.

Setup and Installation

We’ll install necessary libraries and set up...
