Foundational
From Proof-of-Concept to ProductionA notebook that answered one question correctly during a demo is not a deliverable. Production is the unglamorous work that turns a one-time success into a system the customer can run, trust, and operate without you in the room. Closing that gap is most of the FDE job.⚙️ System Design for AI in Production

Model Routing and CascadesModel routing sends each request to the cheapest model that can handle it, escalating only when needed. Most production traffic is easy, so paying frontier prices for every request is usually the largest avoidable line in an AI bill. The engineering is in deciding cheaply and in knowing what to do when the router is wrong.🧠 Foundations of LLMs & GenAI🔒 Premium

Prompt Caching and Semantic CachingTwo different caches solve two different bills. Prompt caching reuses the model's internal computation over a stable prefix, cutting cost and time-to-first-token on every call that shares it. Semantic caching skips the model entirely when a near-identical question has been answered before, and it is the one that can serve a wrong answer confidently.🧠 Foundations of LLMs & GenAI🔒 Premium

Agent Frameworks and How Agents FailFrameworks such as LangGraph, CrewAI and AutoGen give you state, checkpointing and tracing, which is most of what a production agent needs and none of what makes one work. The failure modes they do not fix are the ones that end pilots: loops that never terminate, budgets that blow, and tool-selection errors that compound quietly.🤖 Retrieval & Agents🔒 Premium
