Been doing a very complex refactoring all week. Still an area where LLMs aren't great....
That said. Claude 4 Sonnet Thinking has been a seriously amazing pair programmer.
Always try and push the models beyond what you think they're capable of. You'll almost always be surprised.
I havenāt yet used the Thinking model but Claude 4 Sonnet is such a step up from 3.7!
I had a problem with Claude the other day where it would redo an artifact and be a few new versions but then nothing changed in the final document. I could see it making the right changes, then it spit out the old artifact with a new version on it. I haven't used thinking very much. It also seems to struggle a lot of the project knowledge base is more than 50% full or there abouts.
They suck at doing small changes in huge code.
