Production RAG Platform with Neural Reranking and Infrastructure-as-Code

Scenario

A team trains custom embedding and reranking models on PAI, deploys a hybrid retrieval pipeline (vector + BM25) with Bailian neural reranking into OpenSearch/Elasticsearch, builds a dual-channel RAG chatbot and recommendation system, then provisions and manages the entire production stack (ECS, RDS, OSS, Vercel) using Terraform for repeatable infrastructure-as-code deployment.

Q: How do I build a production RAG platform with custom model training, neural reranking, and infrastructure-as-code? A: You build this platform by training custom embedding and reranking models on PAI, deploying a hybrid retrieval pipeline with Bailian neural reranking into OpenSearch or Elasticsearch, and provisioning the stack with Terraform. This architecture supports a dual-channel RAG chatbot and recommendation system while managing ECS, RDS, OSS, and Vercel resources through repeatable infrastructure-as-code. Detailed implementation steps are documented in the "Full-Stack Custom RAG: Train to Production" and "Custom-Trained RAG with Personalized Recommendation Layer" skill guides.
