Issue with o3-mini-high – Model Not Found Despite Tier 5

API
1

Hi everyone,

I just tried using the o3-mini-high model via API, but I received the following error:
The model o3-mini-high does not exist or you do not have access to it.
I also couldn’t find this model in the limits or model lists, even though I have Tier 5 access.

Is this a temporary issue, or is there something I’m missing? I’d really appreciate any clarification on whether this model is currently available and if I should expect access soon.

By the way, I absolutely love the performance of OpenAI’s new models—thank you for all the amazing work you’re doing! :rocket:

Looking forward to any insights.

Best,
Mykyta

Please do yourself a favor and create a new API key, copy it, debug your code, verify the endpoint addess is not a divergent base URL and make sure the API key is exactly matching. If you can access it in Playground, a mismatch is probable. If your Org is a company, you maybe have to apply for access. My personal Tier 3 account has access, while my company account does not.

Mate, don’t be so rude. I realise that you think you’re pretty smart and I hope you really are. However, I can make request using o3-mini model with the same api keys that I get an error with when calling o3-mini-high.

At the same time I completely realise that I might be missing something.

Here is curl that works:

curl --request POST \
  --url https://api.openai.com/v1/chat/completions \
  --header 'authorization: $apiKey' \
  --header 'content-type: application/json' \
  --data '{
  "model": "o3-mini",
  "messages": [
    {
      "role": "system",
      "content": "You are assistant"
    },
    {
      "role": "user",
      "content": "Tell me a joke"
    }
  ]
}'

Same curl but with o3-mini-high model doesn’t work. I am pretty sure (if I didn’t dream it up) that I was able to do a request to this model or at least see it in limits page 4 days ago.

Okay, I think I really dreamed that up.
o3-mini-high is just the UI appearance on the ChatGPT App lvl. To use it through the API I have to set reasoning_effort as high.

You are right. I also have tier 5 and I cannot see the model on the list.
