How to set o3-mini API

How To
1

I’m using Cursor ver0.45.11 and can use GPT-4o API with no issue.

But when I use the same API key and add a model “o3-mini,” it gives me 404:

(status code 404)
{
“error”: {
“message”: “The model o3-mini does not exist or you do not have access to it.”,
“type”: “invalid_request_error”,
“param”: null,
“code”: “model_not_found”
}
}

What is wrong with my Cursor? Is API access to o3-mini disabled?
Am I supposed to pay $20 for a limited number of access to o3-mini?

Hey, if you have tier 3-5, this might be available to you. If you don’t have access yet, please wait, as OpenAI is doing a rolling release, not to all users at once.
