I'm getting:
Project ... does not have access to model gpt-5-mini-2025-08-07'
Project ... does not have access to model gpt-4o`'
messages when I send API request.

Where I can find available models for my project (not every available models) on the platform.openai.com?

Hi @solid rose. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

You’re running into two separate things:

  1. Your project/org doesn’t have access to those specific models.
  2. The docs pages show all public models, not just what your project can use.

From the knowledge sources, the only API that returns what your org/project can actually call is the Models endpoint:

GET <https://api.openai.com/v1/models>
Authorization: Bearer YOUR_API_KEY
OpenAI-Project: YOUR_PROJECT_ID   # optional but recommended if you use projects

This returns a list of model objects your key/project can use (IDs like gpt-5.2, gpt-5-mini, gpt-4.1, etc.). [API reference][Models API]

Key points:

  • The Models docs describe this explicitly as “Lists the currently available models” for your org. [API reference]
  • The public Models catalog page (/docs/models) shows all models OpenAI offers, not filtered to your account. [Models catalog]

So, to see only the models available to your project:

  1. Call GET /v1/models with your API key (and OpenAI-Project header if you’re using projects).
  2. Use one of the returned id values (e.g. gpt-5.2, gpt-5-mini, etc.) in your model field for API calls.

The knowledge sources do not show any project-specific UI in the dashboard that lists only your allowed models; they only document the API-based listing.
