What is Self-RAG?
0:20
Self-RAG is an approach where the model itself decides when to retrieve information, what to retrieve, and how much to trust the retrieved content. The model is trained to emit special tokens that signal retrieval and self-evaluation steps. This adaptive retrieval avoids unnecessary lookups for queries the model can answer from its own knowledge while improving accuracy on knowledge-intensive queries.
