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\":[\"1928-03-24\"],\"letter_title\":[\"Verkauf\"],\"sender_persons\":[\"Basler Personenschiffahrtsgesellschaft\"],\"receiver_persons\":[\"Basler Rheinschiffahrt A.-G.\"]}}", "model": "gpt-5.6-luna", "provider": "openai", "finish_reason": "stop", "usage": {"input_tokens": 6966, "output_tokens": 186, "total_tokens": 7152, "cached_tokens": 5888, "input_cost_usd": 0.006966, "output_cost_usd": 0.001116, "estimated_cost_usd": 0.008082}, "duration": 12.239630460739136, "timestamp": "2026-07-25T20:37:44.012669", "parsed": {"metadata": {"send_date": ["1928-03-24"], "letter_title": ["Verkauf"], "sender_persons": ["Basler Personenschiffahrtsgesellschaft"], "receiver_persons": ["Basler Rheinschiffahrt A.-G."], "document_number": "letter20"}}, "conversation_id": "66308324-51b4-4a05-9f5f-09b1cc76d2be", "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-E5bXijZ5t7pI8fzepJInv5nR1VBpv\",\"choices\":[{\"finish_reason\":\"stop\",\"index\":0,\"logprobs\":null,\"message\":{\"content\":\"{\\\"metadata\\\":{\\\"letter_title\\\":[\\\"Verkauf\\\"],\\\"receiver_persons\\\":[\\\"Basler Rheinschiffahrt A.-G.\\\"],\\\"send_date\\\":[\\\"1928-03-24\\\"],\\\"sender_persons\\\":[\\\"Basler Personenschiffahrtsgesellschaft\\\"]}}\",\"refusal\":null,\"role\":\"assistant\",\"annotations\":[],\"audio\":null,\"function_call\":null,\"tool_calls\":null,\"parsed\":{\"metadata\":{\"send_date\":[\"1928-03-24\"],\"letter_title\":[\"Verkauf\"],\"sender_persons\":[\"Basler Personenschiffahrtsgesellschaft\"],\"receiver_persons\":[\"Basler Rheinschiffahrt A.-G.\"]}}}}],\"created\":1785004662,\"model\":\"gpt-5.6-luna\",\"object\":\"chat.completion\",\"service_tier\":\"default\",\"system_fingerprint\":null,\"usage\":{\"completion_tokens\":186,\"prompt_tokens\":6966,\"total_tokens\":7152,\"completion_tokens_details\":{\"accepted_prediction_tokens\":0,\"audio_tokens\":0,\"reasoning_tokens\":122,\"rejected_prediction_tokens\":0},\"prompt_tokens_details\":{\"audio_tokens\":0,\"cached_tokens\":5888}}}"}, "scoring": {"f1_macro": 0.54, "f1_micro": 0.66, "cost_summary": {"total_input_tokens": 125565, "total_output_tokens": 5834, "total_tokens": 131399, "input_cost_usd": 0.12556499999999995, "output_cost_usd": 0.03500399999999999, "total_cost_usd": 0.16056900000000002}}, "normalized_score": 54.0}
