About
After studying how companies deploy generative AI applications, I noticed many similarities in their platforms. This post outlines the common components of a generative AI platform, what they do, and how they are implemented. I try my best to keep the architecture general, but certain applications might deviate. This is what the overall architecture looks like. This is a pretty complex system. This post will start from the simplest architecture and progressively add more components. In its simpl
What it can do
Send user query to a generative model and return a response
User query text → Model-generated response
Enhance model context by retrieving external data sources
User query and connected data sources/documents → Augmented context-enriched response
Integrate tools for information gathering to augment model input
Query requiring external tool access → Response informed by tool/tool-fetched data
Apply guardrails to filter and protect inputs and outputs
User query and model output → Validated/sanitized query and safe response
Route queries across multiple models via a model router and gateway
Incoming query and routing rules → Query dispatched to the appropriate model with unified access
Cache responses to optimize latency and cost
Query and prior response data → Cached or freshly computed response with reduced cost/latency
Execute write actions and complex agentic logic
Query requiring multi-step actions or external writes → Completed actions and aggregated results
Monitor and orchestrate the pipeline for observability and debugging
System telemetry and component chain configuration → Monitoring insights and coordinated end-to-end execution
Why it made the leaderboard
A clear, incrementally-built reference architecture for production genAI systems — showing when and why to add RAG, guardrails, model gateways, caching, and orchestration — so you can reason about your own stack instead of copying a diagram blindly.
