A complete AI stack spans 11 layers: model providers, embeddings, vector databases, RAG pipelines, memory and state management, agent frameworks, managed agent platforms, MCP tool integrations, durable workflow execution, security and guardrails, and evaluation/observability. Each layer addresses a distinct concern — from semantic retrieval and multi-step agent reasoning to prompt injection defense and continuous quality measurement. Not every use case needs all 11 layers, but autonomous customer-facing agents typically require the full stack. Architecture should start from the business problem, not the tooling. ## Full article daily.dev links to this article rather than hosting it.
