API-call generate HTTP-404 model_not_found 'gpt-40' does not exist or

I have an API key with all permissions.
I have integrated this key in my application.
Activating the first question generates the following error message:
(The HTTP request failed with HTTP-404: model_not_found ‘gpt-40’ does not exist or you have no access to it.)

The simular application with COHERE API runs well.

This is because the model name is incorrect.
Change it from

gpt-40

to

gpt-4o

gpt-4o (small O-letter instead of zero) with the same error-message.
