Python Tutorial: Create AI Podcasts with Agentic RAG (Llama Index + OpenAI + Eleven Labs)

This tutorial demonstrates how to create an AI podcast generator with Python code. Inspired by Google's NotebookLM podcasts, I walk through the process of how you can programmatically make customized podcasts using large language model tools and models, such as Llama Index, OpenAI, and ElevenLabs.

We’ll cover the following:

- Upload a PDF and create vector embeddings with Llama Index.
- Generate a podcast script using GPT-4o-mini and Retrieval-Augmented Generation (RAG) Agents.
- Convert the script to lifelike audio using Eleven Labs’ text-to-speech API.
- Stitch MP3 audio clips into a cohesive podcast with PyDub.

Whether you’re an AI Engineer, Machine Learning Engineer, Data Scientist, Developer, Content Creator, or Student, this tutorial provides a practical framework to automate text summarization and podcast production with AI.

Hi, thank you again ❤😊. But why don’t you use other api instead of using chatGPT, it’s not better even with charged version
