GPT-4 works great, super impressive, but I am significantly less impressed by OpenAI as a business. I'm still locked out of creating a work account because I used up the two accounts-per-phone number limit that they have hardcoded (with no way to free up one of those slots by deleting an account) and can't create a new account. Dozens of posts on their support forum about the same thing, basically impossible to get any kind of human support from them to resolve it.
