• Follow-up questions to clarify or deepen the conversation
• A clear, satisfying conclusion, often with a feedback request

Once you’ve built the basics, you can layer in advanced features to make your chatbot even more effective.

Advanced Feature Setup

Enhance your chatbot’s capabilities by using advanced APIs and SDK tools to create smoother, more personalized interactions.

Consider adding these features:

• Web crawling for gathering and processing online data
• File processing with options for metadata filtering and reranking
• Multi-agent workflows using the Agents SDK for seamless coordination

The file search tool is especially powerful, offering precise metadata filtering and custom reranking to deliver highly accurate responses.

"With built-in query optimization and reranking, they are able to set up a powerful RAG pipeline without extra tuning or configuration."
