RAG AI Agent with Milvus & Cohere

September 6, 2025

Aladuddin Aladin

This template sets up a Retrieval-Augmented Generation (RAG) AI agent that combines Cohere embeddings, Milvus vector database, and OpenAI GPT-4o for intelligent, context-aware conversations. It automatically ingests new PDF files uploaded to a Google Drive folder, indexes them into Milvus, and makes the content instantly searchable for the AI agent.

With multilingual embedding support from Cohere, scalable storage with Milvus (via Zilliz Cloud), and memory-enabled conversational context, this workflow provides a production-ready setup for enterprise-grade document-based AI assistants.
