RAG Chatbot on Vertex AIGoogle Cloud Architecture Template

A retrieval-augmented chatbot: documents are embedded via Vertex AI into a vector cache, and a Cloud Run chat API grounds LLM answers in retrieved context.

Why this architecture works

  • Grounding LLM responses in retrieved documents slashes hallucination versus raw prompting.
  • The embedding ingest function keeps the vector index fresh as the corpus changes.
  • Memorystore-backed vector lookups keep retrieval latency in single-digit milliseconds.
  • Chat history in Firestore enables multi-turn context without stuffing whole transcripts into prompts.
  • API keys for the model endpoint live in Secret Manager, never in app config.
