Breaking down Anthropic’s Claude Certified Architect track — the domains it tests, the production patterns it expects you to know, and a practical study plan for engineers who already ship LLM systems.
A practical, architecture-first comparison of Retrieval-Augmented Generation and Cache-Augmented Generation, with patterns for combining both in production LLM systems.

From GPT‑4 to Claude‑3, these models have demonstrated remarkable fluency, few‑shot learning, and the ability to generate code, prose, and even art. Yet, as we entered 2026, a new paradigm—Agentic Reasoning Frameworks (ARFs)—has begun to eclipse pure‑LLM pipelines for many enterprise and research use‑cases. ...

Instead of relying solely on a model’s internal parameters, RAG pipelines fetch relevant context from an external knowledge store and inject it into the generation step. The quality, latency, and scalability of that retrieval step hinge on a single, often underestimated component: the vector database. ...
Introduction Retrieval‑augmented generation (RAG) has emerged as a powerful paradigm for building AI systems that can combine the breadth of large language models (LLMs) with the precision of external knowledge sources. While early RAG pipelines were often linear—retrieve → augment → generate—real‑world problems increasingly demand agentic workflows that can reason across multiple steps, maintain context over long interactions, and adapt to heterogeneous domains (e.g., legal, medical, technical documentation). In this article we dive deep into the architectural considerations required to build such agentic, multi‑step, memory‑aware RAG applications. We will: ...
