Third round: [{'role': 'user', 'content': 'What day is today'}, {'role': 'assistant', 'tool_calls': [{'id': '2235c7b1-1b77-42f1-a0d8-6b4be977be3d', 'type': 'function', 'function': {'name': 'weekday', 'arguments': '{"year": 2023, "month": 4, "day": 14}'}}]}, {'role': 'tool', 'content': 'April 14, 2023 is Friday.', 'name': 'weekday', 'tool_call_id': '2235c7b1-1b77-42f1-a0d8-6b4be977be3d'}, {'role': 'assistant', 'content': 'According to the information in API-REPONSE, today is Friday.'}]
