How does retrieval-augmented generation improve the accuracy of language models?
Asked on Nov 23, 2025
Answer
Retrieval-augmented generation (RAG) enhances the accuracy of language models by integrating external information retrieval with generative capabilities, allowing the model to access and incorporate relevant data from a large corpus during the generation process.
Example Concept: RAG combines a retrieval component and a generative model. The retrieval component searches a database or corpus for relevant documents based on the input query. These documents are then used as additional context for the generative model, which produces a more informed and accurate response by leveraging the retrieved information.
Additional Comment:
- RAG helps overcome the limitations of language models that rely solely on pre-trained knowledge, which might be outdated or incomplete.
- The retrieval component typically uses embeddings to find semantically similar documents, enhancing the relevance of the information used.
- This approach is particularly useful for tasks requiring up-to-date or domain-specific knowledge.
- RAG can dynamically adapt to new information without retraining the generative model.
