Every developer eventually hits the same wall: the code compiles, it runs, and it produces the wrong answer — or crashes — and staring at the source code isn’t enough to figure out why. The instinct most beginners reach for is sprinkling print statements everywhere and re-running the program over and over, hoping to narrow down where … Read more
If you’ve moved your .NET work into an AI-native code editor like Cursor over the last year or two, you’ve probably run into the same wall: the editor is great for writing and refactoring code with an AI assistant sitting next to you, but the moment something breaks, you’re stuck reading print statements instead of … Read more
Open a modern AI coding tool today and you’ll often see a dropdown you didn’t have to think about a year ago: a list of two or three model names, sometimes with a note like “best for complex tasks” or “fastest.” Pick the wrong one, and you either wait too long for a simple question … Read more
Millions of developers open GitHub Copilot every day without thinking much about which AI model is actually answering them. That changed again this week. On July 9, 2026, GitHub confirmed that OpenAI’s GPT-5.6 family — three separate models named Sol, Terra, and Luna — is now available inside Copilot, giving developers an explicit choice between … Read more
Every app you use runs on two very different kinds of database work. When you tap “buy” on an order, a database has to record that one purchase, instantly, correctly, without losing it. When a company later asks “how many orders did we get last month, broken down by city,” a database has to scan … Read more
Every high-performance server you’ve ever used — Redis, Nginx, Node.js, HAProxy — has to answer the same basic question millions of times a second: which of the thousands of open network connections it’s holding actually has new data waiting to be read? Loop through every connection and ask “anything new?” and you’ll burn CPU cycles … Read more
Introduction In June 2026, Vercel ran two Ship events — London on June 17, New York City on June 30 — and the core message of both was the same: software deployment has structurally changed. Six months ago, fewer than 3% of Vercel deployments were triggered by coding agents. As of the NYC event, that … Read more
Introduction Most AI application tutorials fall into one of two categories: Python notebooks that stop at the demo, or raw fetch calls to an LLM API that stop before streaming works. Neither is where production JavaScript applications live. The Vercel AI SDK is a TypeScript library that handles the gap between a raw LLM API … Read more
Introduction Most AI tutorials show you how to make a single LLM call. Real applications need more: multiple steps, conditional branching, tool use, state that persists across turns, and the ability to pause for human review before continuing. That is the gap LangGraph fills. LangGraph is a Python library for building stateful, multi-step AI workflows. … Read more
Introduction Anthropic made Extended Thinking generally available for the Claude API on June 26, 2026. Extended Thinking is a mode where Claude works through a problem step by step before generating a final answer — thinking through intermediate reasoning that is visible to developers but not included in the response token count in the same … Read more
