Today we will Discuss:

1. An introduction to Speculative RAG.

2. A review of the Google Research paper that introduced the ideas of Speculative RAG in AI.

💡 AI Concept of the Day: What is Speculative RAG?

Continuing our series about RAG, today we would like to dive into Speculative RAG , a novel dual-model architecture to enhance the efficiency and accuracy of traditional Retrieval Augmented Generation systems. At its core, the technique employs two distinct language models: a smaller specialist LM serving as the RAG drafter, and a larger generalist LM acting as the RAG verifier.
