Some problems need thinking. A complex debugging task, a math proof, or a multi-step architecture decision — these benefit from Claude reasoning through the problem before answering. Extended thinking makes this explicit and controllable. This is Article 12 in the Claude AI — From Zero to Power User series. You should have completed Article 7: Messages API before this article. By the end of this article, you will know how to enable extended thinking, set thinking budgets, and decide when to use it. ...

In February 2025, Andrej Karpathy posted on X: “There’s a new kind of coding I call ‘vibe coding’, where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.” By March 2026, the bill arrived. The CVE Spike Researchers at Georgia Tech track a metric called the Vibe Security Radar. It counts CVEs formally attributed to AI-generated code. Here is what they found in Q1 2026: ...

Anthropic launched a new tool today called Claude Design. It is part of Anthropic Labs — a new sub-brand for experimental products built on Claude. The idea is simple: you describe what you want in plain language, and Claude builds it as a visual artifact — a slide deck, a prototype, a one-pager, or a general design. What Claude Design Does You open Claude Design and type what you need. Something like: “Make a pricing page with three tiers” or “Build a product overview slide deck for a SaaS company.” ...

Anthropic launched a new Claude Code feature on April 14, 2026: Routines. A Routine is a Claude Code automation that runs in Anthropic’s cloud. You set it up once. Then it runs on a schedule, on an API call, or when a GitHub event fires — with your Mac completely off. What Is a Routine? A Routine packages three things together: ...

In January 2026, Anthropic made a quiet change. They blocked Claude Pro and Max subscribers from using Claude through third-party tools. No announcement. No warning. Tools like OpenCode just stopped working overnight. The backlash was immediate. David Heinemeier Hansson — the creator of Ruby on Rails — posted on X: “Confirmation that Anthropic is intentionally blocking OpenCode, and any other 3P harness, in a paranoid attempt to force devs into Claude Code. Terrible policy for a company built on training models on our code, our writing, our everything.” ...

Every time you call the Claude API with the same system prompt, you pay full price for those input tokens. Prompt caching fixes this. Cache your repeated context once, then pay only 10% on every subsequent call. This is Article 11 in the Claude AI — From Zero to Power User series. You should have completed Article 7: Messages API before this article. By the end of this article, you will know how prompt caching works, when it pays off, and how to implement it in your applications. ...

Anthropic released Claude Opus 4.7 on April 16, 2026. Same price as 4.6. But three times more production bugs resolved on the benchmark that matters most to developers. Here is everything that changed — and the one real catch. The 3x Claim: What It Actually Means The “3x” number comes from SWE-bench Verified, specifically the Rakuten production bug subset. SWE-bench is the standard benchmark for AI coding. It gives a model real GitHub issues from real open-source projects. The model has to produce a working fix — not a suggestion, not a comment. A fix. ...

You ask Claude to return JSON, and it usually works. But sometimes it adds extra text, wraps it in markdown code blocks, or returns invalid JSON. Structured output fixes this — it guarantees valid JSON that matches your schema. This is Article 10 in the Claude AI — From Zero to Power User series. You should have completed Article 7: Messages API before this article. By the end of this article, you will know two ways to get reliable structured data from Claude, and when to use each one. ...

If you use a Mac, you probably press Cmd+Space dozens of times a day. That opens Spotlight. It works. But it is basic. Raycast does everything Spotlight does — and a lot more. And the core is free forever. Who is this for? If you are a developer on Mac who wants faster app switching, clipboard history, and integrations with tools like GitHub, Linear, and VS Code — all with a single hotkey — this is for you. ...

Anthropic just built its most powerful model — and decided not to release it to the public. Claude Mythos Preview is real, and the reason it’s restricted has nothing to do with business strategy. It found thousands of zero-day vulnerabilities across every major operating system and every major web browser. Some of those bugs had been hiding for decades. What Is Claude Mythos Preview? Claude Mythos Preview is Anthropic’s most capable model, released April 7, 2026 — but only to a restricted set of security partners. ...
