Claude AI Guide: Tips, Tutorials & Best Practices

Ever been surprised how quickly Claude Code burns through tokens? This article explains why token use is so high, shares 10 practical saving techniques, and covers what happens at the limit: Pro and Max have a 5-hour window and a weekly limit, and extra charges apply only if you turn on usage credits, which bill overage at API rates.

Claude Code has a "bypass permission mode" that executes almost all operations without confirmation. While it's useful for CI/CD pipelines and containerized environments, misuse can lead to prompt injection attacks, data leaks, and irreversible damage. This guide covers the 6 permission modes, specific risks, and how to use bypass mode safely.

We re-compared Claude Code and Codex against the official documentation as of September 2026. Both run in the terminal, IDEs, desktop apps, the cloud, and on your phone, and their core features now match. The differences are whether you can try them for free, whether the sandbox works on Windows, and which plans get computer use and automatic PR review. We cover how pricing and limits work, how to choose in nine scenarios, and corrections to the earlier version.

A comparison of Claude (Anthropic) and ChatGPT (OpenAI) pricing as checked in September 2026: how the free plans differ, $20 Pro/Plus, the $100 and $200 tiers, team seats and API rates. Which one is cheaper flips depending on the tier and how you use it. Find the plan that fits you.

Ever asked a generative AI a question only to hear "that's beyond my knowledge"? Every generative AI has a training data deadline called a knowledge cutoff. Here's a side-by-side comparison of cutoff dates and web search support across 8 major tools.

With Anthropic's Claude Agent SDK, you can build AI agents that autonomously reason and execute tasks. This guide covers everything from core concepts to hands-on implementation.

Claude had three separate entrances for a long time: Chat, Cowork, and Code. On September 16, 2026, two of them — Chat and Cowork — were merged into one, so you no longer have to decide which one to work in, and everything Cowork could do is now available from any conversation. That does not make it all the same thing, though: the Claude app and Claude Code, which runs in your terminal, are still separate, and even inside the app there is a clear split between asking on the spot and handing off a job and letting it run. This article lays out what Claude looks like after the merge and where you should do what, with a map of where the old Cowork features went so that anyone who learned the name Cowork is not left guessing.
