Opus 4.7 is horrible at writing

Just a short rant. I have been working on my Master's thesis and been using Opus 4.6 throughout, and today switched to Opus 4.7 (using it in Claude Code), and man is it bad at writing. It's such a stark contrast, sloppy, unprecise, very empty sentences. Thankfully I have reached the conclusion chapter of the thesis already, and can continue in the web version with 4.6 but boy is it bad.
