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\":[\"1932-10-04\"],\"letter_title\":[\"Best\u00e4tigung des Empfangs und Mitteilung \u00fcber die Erweiterung der Personenschifffahrt\"],\"sender_persons\":[\"Basler Rheinschiffahrt Aktiengesellschaft\"],\"receiver_persons\":[\"Dr. Max Vischer\"]}}", "model": "qwen/qwen3.5-27b-20260224", "provider": "openrouter", "finish_reason": "stop", "usage": {"input_tokens": 8173, "output_tokens": 113, "total_tokens": 8286, "input_cost_usd": 0.001593735, "output_cost_usd": 0.00017627999999999999, "estimated_cost_usd": 0.001770015}, "duration": 10.882357358932495, "timestamp": "2026-04-21T13:41:07.069621", "parsed": {"metadata": {"send_date": ["1932-10-04"], "letter_title": ["Best\u00e4tigung des Empfangs und Mitteilung \u00fcber die Erweiterung der Personenschifffahrt"], "sender_persons": ["Basler Rheinschiffahrt Aktiengesellschaft"], "receiver_persons": ["Dr. Max Vischer"], "document_number": "letter52"}}, "conversation_id": "cc3ed6e9-ab64-4390-a1ff-c6417251ba70", "score": {"send_date_tp": 1, "send_date_fp": 0, "send_date_fn": 0, "sender_persons_tp": 0, "sender_persons_fp": 1, "sender_persons_fn": 2, "receiver_persons_tp": 1, "receiver_persons_fp": 0, "receiver_persons_fn": 0}, "raw_response": "{\"id\":\"gen-1776771656-U4G6NHJ6Y5VhQLFs1Xos\",\"choices\":[{\"finish_reason\":\"stop\",\"index\":0,\"logprobs\":null,\"message\":{\"content\":\"{\\n  \\\"metadata\\\": {\\n    \\\"send_date\\\": [\\n      \\\"1932-10-04\\\"\\n    ],\\n    \\\"letter_title\\\": [\\n      \\\"Best\u00e4tigung des Empfangs und Mitteilung \u00fcber die Erweiterung der Personenschifffahrt\\\"\\n    ],\\n    \\\"sender_persons\\\": [\\n      \\\"Basler Rheinschiffahrt Aktiengesellschaft\\\"\\n    ],\\n    \\\"receiver_persons\\\": [\\n      \\\"Dr. Max Vischer\\\"\\n    ]\\n  }\\n}\",\"refusal\":null,\"role\":\"assistant\",\"annotations\":null,\"audio\":null,\"function_call\":null,\"tool_calls\":null,\"parsed\":{\"metadata\":{\"send_date\":[\"1932-10-04\"],\"letter_title\":[\"Best\u00e4tigung des Empfangs und Mitteilung \u00fcber die Erweiterung der Personenschifffahrt\"],\"sender_persons\":[\"Basler Rheinschiffahrt Aktiengesellschaft\"],\"receiver_persons\":[\"Dr. Max Vischer\"]}},\"reasoning\":null},\"native_finish_reason\":\"stop\"}],\"created\":1776771656,\"model\":\"qwen/qwen3.5-27b-20260224\",\"object\":\"chat.completion\",\"service_tier\":null,\"system_fingerprint\":null,\"usage\":{\"completion_tokens\":113,\"prompt_tokens\":8173,\"total_tokens\":8286,\"completion_tokens_details\":{\"accepted_prediction_tokens\":null,\"audio_tokens\":0,\"reasoning_tokens\":0,\"rejected_prediction_tokens\":null,\"image_tokens\":0},\"prompt_tokens_details\":{\"audio_tokens\":0,\"cached_tokens\":0,\"cache_write_tokens\":0,\"video_tokens\":0},\"cost\":0.001770015,\"is_byok\":false,\"cost_details\":{\"upstream_inference_cost\":0.001770015,\"upstream_inference_prompt_cost\":0.001593735,\"upstream_inference_completions_cost\":0.00017628}},\"provider\":\"Alibaba\"}"}, "scoring": {"f1_macro": 0.53, "f1_micro": 0.54, "cost_summary": {"total_input_tokens": 281791, "total_output_tokens": 6077, "total_tokens": 287868, "input_cost_usd": 0.054949244999999994, "output_cost_usd": 0.00948012, "total_cost_usd": 0.064429365}}, "normalized_score": 53.0}
