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\":[\"1932-12-16\"],\"letter_title\":null,\"sender_persons\":[\"Basler Personenschiffahrtsgesellschaft\"],\"receiver_persons\":[\"Basler Rheinschiffahrt A.-G.\"]}}", "model": "gpt-5.6-sol", "provider": "openai", "finish_reason": "stop", "usage": {"input_tokens": 3727, "output_tokens": 218, "total_tokens": 3945, "cached_tokens": 2816, "input_cost_usd": 0.018635, "output_cost_usd": 0.006540000000000001, "estimated_cost_usd": 0.025175}, "duration": 5.587884902954102, "timestamp": "2026-07-25T20:37:27.733789", "parsed": {"metadata": {"send_date": ["1932-12-16"], "letter_title": null, "sender_persons": ["Basler Personenschiffahrtsgesellschaft"], "receiver_persons": ["Basler Rheinschiffahrt A.-G."], "document_number": "letter59"}}, "conversation_id": "4530817f-61c0-4289-a250-7456ac76b89e", "score": {"send_date_tp": 1, "send_date_fp": 0, "send_date_fn": 0, "sender_persons_tp": 0, "sender_persons_fp": 1, "sender_persons_fn": 0, "receiver_persons_tp": 0, "receiver_persons_fp": 1, "receiver_persons_fn": 0}, "raw_response": "{\"id\":\"chatcmpl-E5bXPHDLaQyhwgNlip4VjycHrpvDk\",\"choices\":[{\"finish_reason\":\"stop\",\"index\":0,\"logprobs\":null,\"message\":{\"content\":\"{\\\"metadata\\\":{\\\"letter_title\\\":null,\\\"receiver_persons\\\":[\\\"Basler Rheinschiffahrt A.-G.\\\"],\\\"send_date\\\":[\\\"1932-12-16\\\"],\\\"sender_persons\\\":[\\\"Basler Personenschiffahrtsgesellschaft\\\"]}}\",\"refusal\":null,\"role\":\"assistant\",\"annotations\":[],\"audio\":null,\"function_call\":null,\"tool_calls\":null,\"parsed\":{\"metadata\":{\"send_date\":[\"1932-12-16\"],\"letter_title\":null,\"sender_persons\":[\"Basler Personenschiffahrtsgesellschaft\"],\"receiver_persons\":[\"Basler Rheinschiffahrt A.-G.\"]}}}}],\"created\":1785004643,\"model\":\"gpt-5.6-sol\",\"object\":\"chat.completion\",\"service_tier\":\"default\",\"system_fingerprint\":null,\"usage\":{\"completion_tokens\":218,\"prompt_tokens\":3727,\"total_tokens\":3945,\"completion_tokens_details\":{\"accepted_prediction_tokens\":0,\"audio_tokens\":0,\"reasoning_tokens\":157,\"rejected_prediction_tokens\":0},\"prompt_tokens_details\":{\"audio_tokens\":0,\"cached_tokens\":2816}}}"}, "scoring": {"f1_macro": 0.54, "f1_micro": 0.67, "cost_summary": {"total_input_tokens": 125565, "total_output_tokens": 4103, "total_tokens": 129668, "input_cost_usd": 0.6278249999999999, "output_cost_usd": 0.12309000000000002, "total_cost_usd": 0.7509149999999999}}, "normalized_score": 54.0}
