Yesterday I used Claude on a different laptop that for some reason had an older version of the Claude Code plugin for VSCode and ran Sonnet 4.6 which I initially did not notice. I felt something was really off. Within half an hour I had several situations when I just could not believe how stupid Claude was (although I was only working on a simple static website). Luckily I eventually checked the version, but that experience made it clear to me how big the progress has been recently.
