Your task is to extract the\n            values of the following keys from the letter and return them in a JSON file where the values\n            corresponding to each key should be stored as a list, even if there is only a single value for a\n            key:\n\n            - letter_title: Title of the letter.\n            - sender_persons: Name(s) of the person(s) who wrote the letter.\n            - send_date: The exact or approximate date the letter was written.\n            - receiver_persons: Name(s) of the person(s) who received the letter.\n\n            Take a deep breath and think step by step about how to best accomplish this goal. Map out all the claims\n            and implications on a virtual whiteboard in your mind. Do not use OCR. Use the ISO format YYYY-MM-DD for\n            dates. If a piece of information is not included in the letter, set the value for the corresponding key\n            to \"null\". Do not return anything except the JSON file.\n\n            EXAMPLE:\n\n            {\n                \"letter_title\": [\"Petition for Environmental Protection\"],\n                \"send_date\": [\"1993-03-12\"],\n                \"sender_persons\": [\"Lisa Simpson\"],\n                \"receiver_persons\": [\"Mayor Joe Quimby\", \"Seymour Skinner\"],\n            }\n\n            OUTPUT:", "results": {"text": "{\"metadata\":{\"send_date\":[\"1928-04-03\"],\"letter_title\":[\"Kauf \u201eRheinfelden\u201c\"],\"sender_persons\":null,\"receiver_persons\":null}}", "model": "gpt-5.6-sol", "provider": "openai", "finish_reason": "stop", "usage": {"input_tokens": 6966, "output_tokens": 195, "total_tokens": 7161, "cached_tokens": 5888, "input_cost_usd": 0.03483, "output_cost_usd": 0.00585, "estimated_cost_usd": 0.04068}, "duration": 9.335676431655884, "timestamp": "2026-07-25T20:37:41.929497", "parsed": {"metadata": {"send_date": ["1928-04-03"], "letter_title": ["Kauf \u201eRheinfelden\u201c"], "sender_persons": null, "receiver_persons": null, "document_number": "letter23"}}, "conversation_id": "54671028-862f-43d5-a003-b448c5f7ca3f", "score": {"send_date_tp": 1, "send_date_fp": 0, "send_date_fn": 0, "sender_persons_tp": 0, "sender_persons_fp": 0, "sender_persons_fn": 2, "receiver_persons_tp": 0, "receiver_persons_fp": 0, "receiver_persons_fn": 0}, "raw_response": "{\"id\":\"chatcmpl-E5bXeneSI5F7CfTK3wqlAGMe8uoMn\",\"choices\":[{\"finish_reason\":\"stop\",\"index\":0,\"logprobs\":null,\"message\":{\"content\":\"{\\\"metadata\\\":{\\\"letter_title\\\":[\\\"Kauf \u201eRheinfelden\u201c\\\"],\\\"receiver_persons\\\":null,\\\"send_date\\\":[\\\"1928-04-03\\\"],\\\"sender_persons\\\":null}}\",\"refusal\":null,\"role\":\"assistant\",\"annotations\":[],\"audio\":null,\"function_call\":null,\"tool_calls\":null,\"parsed\":{\"metadata\":{\"send_date\":[\"1928-04-03\"],\"letter_title\":[\"Kauf \u201eRheinfelden\u201c\"],\"sender_persons\":null,\"receiver_persons\":null}}}}],\"created\":1785004658,\"model\":\"gpt-5.6-sol\",\"object\":\"chat.completion\",\"service_tier\":\"default\",\"system_fingerprint\":null,\"usage\":{\"completion_tokens\":195,\"prompt_tokens\":6966,\"total_tokens\":7161,\"completion_tokens_details\":{\"accepted_prediction_tokens\":0,\"audio_tokens\":0,\"reasoning_tokens\":144,\"rejected_prediction_tokens\":0},\"prompt_tokens_details\":{\"audio_tokens\":0,\"cached_tokens\":5888}}}"}, "scoring": {"f1_macro": 0.58, "f1_micro": 0.56, "cost_summary": {"total_input_tokens": 219673, "total_output_tokens": 7830, "total_tokens": 227503, "input_cost_usd": 1.0983649999999996, "output_cost_usd": 0.2349, "total_cost_usd": 1.3332650000000001}}, "normalized_score": 57.99999999999999}
