RAG Fine-Tuning: RAFT, RA-DIT & Distillation in RAG & Retrieval SystemsInterview Readiness Check

Teaching the model to use retrieved context better. RAFT (distractor-aware training), RA-DIT (dual retriever+generator tuning), cross-encoder distillation to bi-encoder, small-model distillation from frontier traces. When fine-tuning beats prompt engineering — and when the six cheaper alternatives fix the same problem..

Try a sample question

A standard RAG system uses a general-purpose embedding model. After deployment in a medical domain, retrieval precision is low because domain terminology like 'myocardial infarction' doesn't match 'heart attack' in the embedding space. What is the most targeted fix?

A.Fine-tune the embedding model on medical document-query pairs so the model learns domain-specific semantic equivalences like 'myocardial infarction' ↔ 'heart attack'
B.Expand the chunk size so each chunk contains more synonyms and context
C.Add a keyword search layer using medical ontologies as a synonym dictionary
D.Switch to a larger general embedding model (3072 dimensions) for better coverage
