I assume this doesn't have anything to do with their speed improvements. Grok 4.5 is so fast, it's great. And only $10/month subscription. It's slightly less censored as well.
I tried to use Grok once, but it required a Twitter Blue subscription, which required a 30-day-old Twitter account and for some reason they kept flagging my account for fraud sooner than that. Are they still doing these requirements?
No Twitter for me, just throwaway email.
