The specified model does not exist or access to it is denied.

The 404 status error in the OpenAI API, indicating that the model does not exist or you do not have access to it, can be due to several reasons:

Incorrect Model Name

• The model name opaaaaaaaa might be incorrect or mistyped, as OpenAI models have specific names (e.g., gpt-3.5-turbo, gpt-4o).

Access Restrictions

• You may not have the necessary access tier or permissions to use the specified model. For example, some models like o1 or gpt-4o are only accessible to certain tiers, such as Tier 5 users.

Endpoint or Parameter Issues

• The error could be due to using the wrong endpoint or incorrect parameters when calling the API. Each model might have specific requirements for how it is accessed.

Model Availability

• The model might not be available or might have been deprecated. Newer models or specific versions might not be accessible immediately after their announcement, or they might be subject to rollout delays.
