I'm in Tier 4, and not far off from Tier 5. The docs aren't quite transparent enough to show that if I buy credits if I'll be bumped up to Tier 5, or if I actually have to use enough credits to get into Tier 5. Edit, w/ real time follow up: Prior to buying the credits, I saw O1-preview in the Tier 5 model list as a Tier 4 user. I bought credits to bump to Tier 5—not much, I'd have gotten there before the end of the year. The OpenAI website now shows I'm in Tier 5, but O1-preview is not in the Tier 5 model list for me anymore. So sneaky of them!
