2. Retrieves the most relevant chunks
3. Provides them as context to the AI model
4. Generates an accurate, grounded response

## Best Practices

<AccordionGroup>
  <Accordion title="Chunk size matters">
    Ansa automatically chunks documents into \~500 token segments. For best results, use well-structured documents with clear headings.
  </Accordion>

  <Accordion title="Quality over quantity">
    A smaller, high-quality knowledge base often performs better than a large one with irrelevant content.
  </Accordion>

  <Accordion title="Keep content updated">
    Regularly update your documents to ensure your agent has accurate information.
  </Accordion>

  <Accordion title="Test your knowledge base">
    After uploading, ask questions to verify your agent can find and use the information correctly.
