o1-pro and o1 with vision are open to the users with paid subscription now! But we have to disable o1-mini for free users as the error rate increase again.
o1-pro example: The o1-pro gives me a long long analyze for our logo.

Our $200 pro account is banned by OpenAI, it's only 1 day after we make the payment. So we have to disable the o1-pro for now. We would add more restrictions to the usages and make it back again.

All the services from OpenAI are down from 2 hr ago. So our service is also not avaliable. Need to wait for openai to fix it.

Service is restored.

As OpenAI is down, so our service is not avaliable now. Would restore the service after it fixed.
