Episode notes
Sales Bot Challenge
- Jerry Liu wanted to build a sales bot using GPT-3 to synthesize to-do lists from customer conversations.
- He faced challenges with GPT-3's limited prompt size when trying to input long transcripts.
Two Augmentation Methods
- Two ways exist for augmenting language models with private data: fine-tuning via gradient descent and retrieval augmentation.
- Fine-tuning is less accessible due to cost, data preparation, and evaluation complexity.
Retrieval-Augmented Generation
- Retrieval-augmented generation involves storing data chunks with embeddings in a vector database.
- During query time, top-k retrieval finds relevant chunks, which are then injected into the prompt.
