🔗 Blog Post - nader.substack.com/p/supercharge-your-gpt-model-custom
🔗 GPT Repository Loader - github.com/mpoon/gpt-repository-loader

We'll start by creating a new project and installing the dependencies.

We'll then walk through creating each interaction from modeling the data, to uploading it to OpenAI, and testing it out.

By the end of the video you should be able to build out your own custom models.
