Invalid parameter: the specified response format is not supported with the current model.

The error you are encountering, specifically the 400 status error with the message "Invalid parameter: 'response_format' of type 'json_object' is not supported with this model," is due to several reasons related to the compatibility and configuration of the response_format parameter:

Model Compatibility

The response_format parameter set to {"type": "json_object"} is not supported by the model you are using. Different models in the OpenAI API have varying levels of support for different response formats, and the model you are using does not support the json_object format.

Tool Type Constraints

When using the response_format of type json_object or json_schema, all tools specified in the request must be of type function. If other types of tools, such as file_search or code_interpreter, are included, it will trigger this error.

This mismatch between the requested response format and the capabilities of the model or tools being used results in the 400 status error.
