Our summary
This guide shows how to build a system that answers customer questions using a cheaper AI assistant. Businesses use this setup to save money on software costs while making sure the messages sent to users are actually based on official company documents.
A basic AI assistant writes a draft answer using retrieved source documents. Then, Jev—an AI tool that chooses from options rather than writing an answer—checks if the draft uses the evidence and addresses the question. Failed drafts go to a stronger AI or a human.
This approach is useful for customer support teams who want to lower their software bills safely. However, the results happened in a small test of fifty questions. The system still sent some answerable questions to a human, meaning it will not perfectly handle every message.
Key takeaways
- Require the AI assistant to actually answer the customer's question instead of just repeating facts.
- Record every choice the software makes so you can track your total costs and mistakes.
- Send the message to a human worker if neither the cheap nor the expensive AI succeeds.
