A RAG-based approach for customer support chatbots offers several key benefits:

1. **Improved Accuracy:** It grounds responses in a specific knowledge base, reducing hallucinations and providing more factual answers.
2. **Up-to-date Information:** You can easily update the knowledge base with the latest information without retraining the entire model.
3. **Contextual Understanding:** It can retrieve relevant documents to better understand and answer complex, domain-specific user queries.
4. **Transparency:** You can see which source documents were used to generate a response, making it easier to verify accuracy and troubleshoot issues.
