Like what? In my experience, there are very few things that GPT-4 is definitively better at. It's good at explaining stuff, but not so good that I would deliberately avoid ChatGPT to use it. It's alright at coding, but code-optimized models regularly beat it in benchmarks. Plus, it's got the same lame filter and even an arbitrary request limit for paying customers.
I struggle to really imagine the "mysterious things you can do on advanced AI" that is impossible or impractical on local models. In my time using GPT-4, I was not really left wanting for more so much as I wanted it to stop saying "As an AI model..."

Evidently, people like you.
I feel it's a lot like looking at art. If you're happy with dogs playing poker painted on velvet then that's good for you, but I'm looking for something a little more satisfying. If your customers are happy with dogs playing poker painted on velvet then that's doubly good for you.
I've been trying to learn Chinese for a while, and GPT-4 has been a very useful tool to answer grammar questions. I have tried the same with GPT-3.5 and some local models and the answers are never as good.
