@hackproduct9: The AI demo is usually the easy part. ⚡ Prompt → LLM → Response Looks great in an afternoon. Then production shows up. Now you need auth, gateways, prompt versioning, model routing, RAG, vector search, tools, memory, guardrails, observability, evals, retries, fallbacks, deployment, scaling… and suddenly the model call is the smallest box in the system. That’s the part AI engineering tutorials often skip. The hard problem isn’t: “Can the model answer?” It’s: “Can the entire system keep answering correctly, safely, cheaply, and reliably when real users show up?” A production AI app is less about calling an LLM. It’s about engineering everything around that call. 3 boxes in the demo. 14+ in production. #AIEngineering #LLM #GenerativeAI #RAG #SystemDesign
