Unrecognized request argument supplied. Please check the parameters provided in the request.

The error "Unrecognized request argument supplied: openai_api_key" with a 400 status code in the OpenAI API typically indicates that the API request contains an invalid or unrecognized parameter. Here are some possible reasons for this error:

• Incorrect Parameter Name: The parameter openai_api_key is not a valid argument for the OpenAI API endpoints. API keys should be passed in the Authorization header, not as a request body parameter.

• Invalid Request Structure: The API request might be structured incorrectly, with the API key or other parameters placed in the wrong location or with incorrect naming conventions.

• Model-Specific Parameters: Different models or API versions might have specific parameters that are recognized, and using an unrecognized parameter can result in this error. For example, some models use max_tokens while others use max_completion_tokens.

In general, this error signifies that the request does not conform to the expected format or parameters as defined in the OpenAI API documentation.
