Today, I found myself deep in a technical challenge, anticipating issues but driven by the excitement of discovery. As a developer, I’ve learned that hands-on experience with tools often provides more insight than any documentation or tutorial. This time, my focus was on LangGraph Checkpointers a mechanism for managing state in distributed workflows. What began as a casual experiment turned into an enlightening journey into state persistence, distributed systems, and the comp

When I began working with large language models (LLMs), I was amazed by their ability to generate human-like text and tackle complex queries. However, I quickly recognized a crucial limitation: while LLMs excel at producing coherent output, they struggle with intricate, multi-step problems. They resemble brilliant improvisers but lack the structured approach necessary to navigate the hidden complexities of real-world tasks. This realization led me to Agentic Design Patterns

Why Routing Matters When I first began building multi-model AI systems, I quickly discovered that routing was not merely a technical detail, it was the backbone of the system's efficiency and scalability. Routing dictates how queries are processed, balancing cost, accuracy, and latency to optimize the system's "thinking budget." Without effective routing, you risk overloading expensive models with trivial tasks or missing the mark with lightweight models that lack the capabil
