Which is still horrifically slow and unoptimized. I’m not sure why streaming tokens from an api into an electron app is difficult but OpenAI managed to bungle it somehow.
Also, you may be underestimating how buggy Swift and the rest of Apple's stack are. It's hard to get those bugs resolved unless you happen to work at Apple. Thus, a lot of time is spent working around bugs up the stack. So I don't find it surprising that a company moving fast like OpenAI ships _some_ bugs. The mac app just came out this month? Give it time.
