You don't have to use adaptive thinking. It had been turned off on my main work computer. I was using a different computer on a trip and I started getting so angry at Claude for doing a bad job. I evetually figured out it was adaptive thinking and set it to "hard" and it started working again. At the time I think "hard" was the top choice. With 4.7, my computer now shows "xhard", which I assume is the equivelent setting. There is one higher setting than this, which I haven't tried yet. I would tell you how to change these settings, but I don't remember. By the way, I have been happy with 4.7 so far. I actually did not like 4.6 and preferred 4.5 and used that most of the time until this new release.
