Designing
Generative AI Systems

Move beyond the prompt. Learn how to architect robust, scalable, and safe AI applications using Routers, RAG, and Agents.

Building Blocks

A production AI system is more than just a model API call. It requires a supporting cast of infrastructure.

Model Router

(Click to reveal)

The Traffic Controller

Dynamically directs user requests to the best model.

Simple query? Use a fast 7B model.
Complex logic? Route to GPT-4.

Guardrails

(Click to reveal)

Safety Layer

Intercepts inputs and outputs.

Prevents PII leakage, blocks jailbreak attempts, and filters toxic content before it reaches the user.

Vector Store

(Click to reveal)

Long-Term Memory

Stores domain knowledge as embeddings.

Allows the LLM to access millions of documents via RAG (Retrieval Augmented Generation).

Orchestrator

(Click to reveal)

The Brain

Frameworks like LangChain or LangGraph that manage the flow.

They handle tool execution, retries, and maintaining conversation history.

Architectural Patterns

Retrieval-Augmented Generation

Best for: Question Answering over private data.

1
Ingestion: Documents are chunked and embedded into vectors.
2
Retrieval: User query fetches top-K relevant chunks.
3
Synthesis: LLM generates answer using ONLY retrieved context.

Architectural Review

Test your system design knowledge.

1. What is the primary purpose of a "Router" in GenAI architecture?

2. Where should "Guardrails" be placed in the stack?

3. Which component acts as the "Long-Term Memory" for the system?
