Tier 5 OpenAI API, but no o1 access

When can I use it properly? Please answer.

Error code: 404 - {‘error’: {‘message’: ‘The model o1 does not exist or you do not have access to it.’, ‘type’: ‘invalid_request_error’, ‘param’: None, ‘code’: ‘model_not_found’}}

Hi there! Could you let me know how long you’ve been at Tier 5?

I’m dealing with the same issue, but I’m currently at Tier 3.
