Connection to OpenAI API failed. This typically occurs due to incorrect configuration or OpenAI API account issues. Please check your settings and verify your OpenAI API account status.

API Error: Status Code 400, { "error": { "message": "Unsupported parameter: 'temperature' is not supported with this model.", "type": "invalid_request_error", "param": "temperature", "code": "unsupported_parameter" } }

Hi, o3 like o1 does no support parameter like temperature. You need to implement it like o1-mini, but o1 mini does not support reasoning parameter. You can see this PR #1818
