I am only seeing two models on my openai cgpt API

API
1 
(test) pegasus@pegasus:~/Documents/gpt_test$ curl https://api.openai.com/v1/models \
  -H "Authorization: Bearer $OPENAI_API_KEY"
{
  "object": "list",
  "data": [
    {
      "id": "gpt-4o",
      "object": "model",
      "created": 1715367049,
      "owned_by": "system"
    },
    {
      "id": "gpt-4o-mini",
      "object": "model",
      "created": 1721172741,
      "owned_by": "system"
    }
  ]
}(test)

For my organization I need cheaper and newer models like 4.1.nano, 5.4.nano
But unable to use that.
I even bought 5 usd credit for API usage. And verified my individual account with National ID.

I am usage tier 1.
But how can I break from this limitation and access more model?

I have resolved the issue. There is a project level limits. Inside it there is block and allow list.
From there many other models can be added
