I can use o1 via 3rd parties but not via my Tier 5 API key. I had an email saying that it has been rolled back and that nobody has acces to it , but this does not seem to be accurate since I can acces it via 3rd parties without issue. I would rather give open ai my money than some 3rd party reseller.
The roll-out appears to be happening over the course of a couple of weeks. I’m also Tier 5 and don’t have access yet.
