Claude just released a brand new model called Opus 4.8, but the thing most people are missing is a new setting that quietly launched right alongside it. In this video, I will show you what is actually new in Opus 4.8 and how to use the new effort control to get better answers, no matter what you use Claude for.

We will start with a quick, honest look at what changed in Opus 4.8, including where it improved and where it did not, so you know what to actually expect. Then I will walk you through the new effort control, the setting that lets you decide how hard Claude thinks about your request, and show you the real difference between the lowest and highest levels using a simple example. You do not need to be a coder for any of this. It works the same whether you use Claude in your browser, on your phone, in Claude Code, or in the Cowork app, and the whole thing takes just a couple of minutes to understand. By the end you will know exactly when to turn the effort up, when to leave it alone, and how to get more out of every answer.
