Funnily enough, I test code generation both on unpaid Claude and ChatGPT.<p>When working with Python, I've found Sonnet (pre 3.5) to be quite superior to ChatGPT (mostly 4, sometimes 3.5) with regards to verbosity, structure and prompt / instruct comprehension.<p>I've switched to a JavaScript project two weeks ago and the tables have turned.<p>Sonnet 3.5 is much more verbose and I need to make corrections a few times, whereas ChatGPTs output is shorter and on point.<p>I'll closely follow if this improves if Claude are focussing on JS themselves.
