### Answer Yes, you can view Knowledge Base retrieval chunks directly within the Test LLM feature. [(1) ]() This update provides visibility into how the Knowledge Base is being used—you can check if questions are retrieving the correct information and make adjustments as needed. However, there's a known behavior difference: some users have reported that Knowledge Base retrieval works during audio calls but may not consistently show retrieval in the text-based "Test LLM" playground. [(2) ]() If you're not seeing retrieval in the playground but it works on actual calls, this appears to be a recognized inconsistency. To test your Knowledge Base: - Add the Knowledge Base to your agent - Ask related questions in the Test LLM area - The agent should automatically reference the content without requiring prompt changes [(3) ]() If retrieval still isn't appearing, ensure: 1. The Knowledge Base status is "complete" (not "in_progress" or "error") [(4) ]() 2. The KB is properly linked to your agent in the agent editor [(3) ]()
