I don't agree. I avoided grok because of Musk for a long time, but having used it more, I think it is one the best models around and grok.com is an extremely good chat app. My evaluation was based on trying it before gpt-5.5 and obvious before grok 4.3, but it was, for me, the 2nd best model/chat app after claude. It's much less edgelordy than you might think based on the news.
All my usage of Grok for technical topics shows it regularly deeply misunderstanding things and just parroting back my question in fancy language. It’s the only frontier model I get this impression of. That makes it super annoying when it tries to market itself as good at engineering tasks when it seems (to me) to be much worse at them.
