I often use Claude 3.7 on programming things never done before. Even extensive search in the web brings up zero hits. I understand that this is very uncommon but my work portfolio is more science than real programming. Claude 3.7 really „thinks“ about the questions i ask. But 3.5 regularly drifts into dream mode if asked anything over it‘s training data. So if you ask for code easy found on the web you will see no difference. Try asking things not so common and you will see a difference
