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\":[\"1926-02-16\"],\"letter_title\":[\"null\"],\"sender_persons\":[\"Basler Rheinschiffahrt-Aktiengesellschaft\"],\"receiver_persons\":[\"Herrn Christ\"]}}", "model": "z-ai/glm-5.3-flash", "provider": "openrouter", "finish_reason": "stop", "usage": {"input_tokens": 11865, "output_tokens": 82, "total_tokens": 11947, "input_cost_usd": 0.000889875, "output_cost_usd": 2.05e-05, "estimated_cost_usd": 0.000910375}, "duration": 9.894886493682861, "timestamp": "2026-09-08T09:45:06.131731", "parsed": {"metadata": {"send_date": ["1926-02-16"], "letter_title": ["null"], "sender_persons": ["Basler Rheinschiffahrt-Aktiengesellschaft"], "receiver_persons": ["Herrn Christ"], "document_number": "letter01"}}, "conversation_id": "6f718b6c-3c37-4877-89f5-78bd6949de6f", "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-1788853496-v0QLYveQDPfxA8m3iufg\",\"choices\":[{\"finish_reason\":\"stop\",\"index\":0,\"logprobs\":null,\"message\":{\"content\":\"{\\n    \\\"metadata\\\": {\\n        \\\"send_date\\\": [\\n            \\\"1926-02-16\\\"\\n        ],\\n        \\\"letter_title\\\": [\\n            \\\"null\\\"\\n        ],\\n        \\\"sender_persons\\\": [\\n            \\\"Basler Rheinschiffahrt-Aktiengesellschaft\\\"\\n        ],\\n        \\\"receiver_persons\\\": [\\n            \\\"Herrn Christ\\\"\\n        ]\\n    }\\n}\",\"refusal\":null,\"role\":\"assistant\",\"annotations\":null,\"audio\":null,\"function_call\":null,\"tool_calls\":null,\"parsed\":{\"metadata\":{\"send_date\":[\"1926-02-16\"],\"letter_title\":[\"null\"],\"sender_persons\":[\"Basler Rheinschiffahrt-Aktiengesellschaft\"],\"receiver_persons\":[\"Herrn Christ\"]}},\"reasoning\":null},\"native_finish_reason\":\"stop\"}],\"created\":1788853496,\"model\":\"z-ai/glm-5.3-flash\",\"object\":\"chat.completion\",\"service_tier\":null,\"system_fingerprint\":\"vllm-0.1.dev20051+g487ecf187-tp8-53169669\",\"usage\":{\"completion_tokens\":82,\"prompt_tokens\":11865,\"total_tokens\":11947,\"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\":0.00182075,\"is_byok\":false,\"cost_details\":{\"upstream_inference_cost\":0.00182075,\"upstream_inference_prompt_cost\":0.00177975,\"upstream_inference_completions_cost\":0.000041}},\"provider\":\"Reka\"}"}, "scoring": {"f1_macro": 0.55, "f1_micro": 0.56, "cost_summary": {"total_input_tokens": 395916, "total_output_tokens": 6312, "total_tokens": 402228, "input_cost_usd": 0.0296771512, "output_cost_usd": 0.0015675, "total_cost_usd": 0.0312446512}}, "pricing": {"bucket_date": "2026-09-08", "age_days": 0, "input_price_per_million": 0.075, "output_price_per_million": 0.25}, "timing": {"total_response_s": 318.83, "mean_response_s": 5.59, "slowest_response_s": 34.93, "inputs_timed": 57, "inputs_stored": 57, "span_s": 53.11}, "normalized_score": 55.00000000000001}
