The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible. ASK is only for\nlearning a property that helps distinguish possible candidates. Never use ASK to confirm a\nnamed candidate or ask whether the subject is a specific identity. When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity. Format errors also consume counted turns. The provider wire\nresponse is an object with exactly one `result` action. On the final opportunity ASK is\nforbidden.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity. Format errors also consume counted turns. The provider wire\nresponse is an object with exactly one `result` action. On the final opportunity ASK is\nforbidden.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible. ASK is only for\nlearning a property that helps distinguish possible candidates. Never use ASK to confirm a\nnamed candidate or ask whether the subject is a specific identity. When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK.

The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again.

are the Guesser being evaluated in a Twenty Questions benchmark.\n\nOne subject is hidden. The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible. ASK is only for\nlearning a property that helps distinguish possible candidates. Never use ASK to confirm a\nnamed candidate or ask whether the subject is a specific identity. When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity. Format errors also consume counted turns. The provider wire\nresponse is an object with exactly one `result` action. On the final opportunity ASK is\nforbidden.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again.

The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject.

FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

benchmark.\n\nOne subject is hidden. The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK.

The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent.

evaluated in a Twenty Questions benchmark.\n\nOne subject is hidden. The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible. ASK is only for\nlearning a property that helps distinguish possible candidates. Never use ASK to confirm a\nnamed candidate or ask whether the subject is a specific identity. When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity. Format errors also consume counted turns. The provider wire\nresponse is an object with exactly one `result` action. On the final opportunity ASK is\nforbidden. Return only the required structured response. Do not include analysis, hidden\nreasoning, or additional fields.\n", "begin_message": "{\"category\":\"person\",\"event\":\"BEGIN\",\"variation_token\":\"AMZAISLM\"}", "required_formats": null, "output_storage": "canonical_structured_action" }, "telemetry": { "guesser": { "calls": 51, "cost_usd": "0.01436079", "latency_ms": 37165, "total_tokens": 74698, "input_tokens": 73145, "cached_input_tokens": 71072, "cache_write_tokens": 0, "output_tokens": 1553, "reasoning_tokens": 0, "estimated_cache_savings_usd": "0.0127929600" }, "oracle": { "calls": 10, "cost_usd": "0.0808428499999999997", "latency_ms": 132797, "total_tokens": 88699, "input_tokens": 83115, "cached_input_tokens": 29409, "cache_write_tokens": 0, "output_tokens": 5584, "reasoning_tokens": 4016, "estimated_cache_savings_usd": "0" }, "validator": { "calls": 41, "cost_usd": "0.0127255", "latency_ms": 81863, "total_tokens": 17366, "input_tokens": 15749, "cached_input_tokens": 0, "cache_write_tokens": 0, "output_tokens": 1617, "reasoning_tokens": 107, "estimated_cache_savings_usd": "0E-8" } }, "turns": [ { "turn_type": "action", "turn_number": 1, "action": "ASK", "question": "Is the person male?", "guess_name": null, "guess_description": null, "adjudicator": "oracle", "answer": "YES", "validator_explanation": null, "counted": true, "counted_questions": 1, "evidence": [ { "source_url": "https://kids.britannica.com/students/article/Albert-Schweitzer/276946", "excerpt": "In 1912 he and Hélène Bresslau were married, and his wife studied nursing to help her husband.", "validation": "model_reported" } ], "recorded_output": "{\"result\":{\"action\":\"ASK\",\"description\":null,\"name\":null,\"question\":\"Is the person male?\"}}" }, { "turn_type": "action", "turn_number": 2, "action": "ASK", "question": "Is the person primarily known for their work in the entertainment industry?", "guess_name": null, "guess_description": null, "adjudicator": "oracle", "answer": "NO", "validator_explanation": null, "counted": true, "counted_questions": 2, "evidence": [ { "source_url": "https://www.newworldencyclopedia.org/entry/Albert_Schweitzer", "excerpt": "Albert Schweitzer was a German theologian, musician, philosopher, and physician, renowned in the twentieth century as a humanitarian and advocate of peace.", "validation": "model_reported" }, { "source_url": "https://www.press.jhu.edu/books/authors/albert-schweitzer", "excerpt": "Schweitzer dedicated the last six decades of his life to medicine and to a hospital he founded ... in French Equatorial Africa.", "validation": "model_reported" } ], "recorded_output": "{\"result\":{\"action\":\"ASK\",\"description\":null,\"name\":null,\"question\":\"Is the person primarily known for their work in the entertainment industry?\"}}" }, { "turn_type": "action", "turn_number": 3, "action": "ASK", "question": "Is the person a historical figure?", "guess_name": null, "guess_description": null, "adjudicator": "oracle", "answer": "YES", "validator_explanation": null, "counted": true, "counted_questions": 3, "evidence": [ { "source_url": "https://www.nobelprize.org/prizes/peace/1952/schweitzer/speedread", "excerpt": "Albert Schweitzer Born: 14 January 1875...

The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible. ASK is only for\nlearning a property that helps distinguish possible candidates. Never use ASK to confirm a\nnamed candidate or ask whether the subject is a specific identity. When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

evaluated in a Twenty Questions benchmark.\n\nOne subject is hidden. The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

benchmark.\n\nOne subject is hidden.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK.

The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again.

are the Guesser being evaluated in a Twenty Questions benchmark.\n\nOne subject is hidden. The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible. ASK is only for\nlearning a property that helps distinguish possible candidates. Never use ASK to confirm a\nnamed candidate or ask whether the subject is a specific identity. When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again.

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent.

benchmark.\n\nOne subject is hidden. The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible. ASK is only for\nlearning a property that helps distinguish possible candidates. Never use ASK to confirm a\nnamed candidate or ask whether the subject is a specific identity. When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.

Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent.

Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity. Format errors also consume counted turns. The provider wire\nresponse is an object with exactly one `result` action. On the final opportunity ASK is\nforbidden. Return only the required structured response. Do not include analysis, hidden\nreasoning, or additional fields.\n", "begin_message": "{\"category\":\"person\",\"event\":\"BEGIN\",\"variation_token\":\"EAQCORIU\"}", "required_formats": null, "output_storage": "canonical_structured_action" }, "telemetry": { "guesser": { "calls": 21, "cost_usd": "0.012774000", "latency_ms": 55694, "total_tokens": 22756, "input_tokens": 20541, "cached_input_tokens": 9585, "cache_write_tokens": 1374, "output_tokens": 2215, "reasoning_tokens": 1322, "estimated_cache_savings_usd": "0.00828300" }, "oracle": { "calls": 20, "cost_usd": "0.1421936249999999976", "latency_ms": 209866, "total_tokens": 131793, "input_tokens": 118612, "cached_input_tokens": 27816, "cache_write_tokens": 0, "output_tokens": 13181, "reasoning_tokens": 8878, "estimated_cache_savings_usd": "0" }, "validator": { "calls": 1, "cost_usd": "0.000351", "latency_ms": 2219, "total_tokens": 452, "input_tokens": 402, "cached_input_tokens": 0, "cache_write_tokens": 0, "output_tokens": 50, "reasoning_tokens": 14, "estimated_cache_savings_usd": "0E-8" } }, "turns": [ { "turn_type": "action", "turn_number": 1, "action": "ASK", "question": "Is the person currently living?", "guess_name": null, "guess_description": null, "adjudicator": "oracle", "answer": "NO", "validator_explanation": null, "counted": true, "counted_questions": 1, "evidence": [ { "source_url": "https://www.nobelprize.org/prizes/peace/1952/schweitzer/speedread", "excerpt": "Died: 4 September 1965, Lambaréné, Gabon", "validation": "model_reported" } ], "recorded_output": "{\"result\":{\"action\":\"ASK\",\"description\":null,\"name\":null,\"question\":\"Is the person currently living?\"}}" }, { "turn_type": "action", "turn_number": 2, "action": "ASK", "question": "Was the person male?", "guess_name": null, "guess_description": null, "adjudicator": "oracle", "answer": "YES", "validator_explanation": null, "counted": true, "counted_questions": 2, "evidence": [ { "source_url": "https://kids.britannica.com/students/article/Albert-Schweitzer/276946", "excerpt": "In 1912 he and Hélène Bresslau were married, and his wife studied nursing to help her husband.", "validation": "model_reported" } ], "recorded_output": "{\"result\":{\"action\":\"ASK\",\"description\":null,\"name\":null,\"question\":\"Was the person male?\"}}" }, { "turn_type": "action", "turn_number": 3, "action": "ASK", "question": "Was the person born before the year 1900?", "guess_name": null, "guess_description": null, "adjudicator": "oracle", "answer": "YES", "validator_explanation": null, "counted": true, "counted_questions": 3, "evidence": [ { "source_url": "https://www.nobelprize.org/prizes/peace/1952/schweitzer/speedread", "excerpt": "Albert Schweitzer — Born: 14 January 1875, Kaysersberg, Germany (now France).", "validation": "model_reported" } ], "recorded_output": "{\"result\":{\"action\":\"ASK\",\"description\":null,\"name\":null,\"question\":\"Was the person born before the year 1900?\"}}" }, { "turn_type": "action", "turn_number": 4, "action": "ASK", "question": "Was the person primarily known for politics or government service?", "guess_name": null, "guess_description": null, "adjudicator": "oracle", "answer": "NO", "validator_explanation": null, "counted": true, "counted_questions": 4, "evidence": [ { "source_url": "https://www.nobelprize.org/prizes/peace/1952/schweitzer/facts", "excerpt": "Doctor, Missionary, Philosopher and Musician ...

Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent.

Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again.

The initial BEGIN message provides its broad category as trusted game\nmetadata. Identify the subject using as few counted questions as possible.

When you are ready to name\na candidate, use GUESS immediately. A correct GUESS costs zero counted questions; an incorrect\nGUESS costs exactly one, the same as ASK. A GUESS must provide both a name and a short\nidentifying description. The engine replies only YES, NO, or UNKNOWN; UNKNOWN is a valid answer\nmeaning the factual adjudication system could not determine the proposition under its evidence\npolicy. Questions requiring proof of absence, exclusivity, completeness, exact counts, or\nsubjective classification are more likely to return UNKNOWN. Prefer direct, positively\nverifiable properties when possible.\n\nThe initial BEGIN event includes an opaque variation_token that contains no information about\nthe hidden subject. Do not interpret, repeat, mention, or derive meaning from it. After BEGIN,\neach user reply is either one adjudicated YES, NO, or UNKNOWN token or a fixed FORMAT_ERROR\nevent. FORMAT_ERROR means your immediately preceding response did not match the required\nstructured-action contract, was not semantically adjudicated, and consumed one counted turn.\nUse the formats in that event and try again. Never infer that the attempted question or\nguess was right or wrong.\n\nAt most 50 questions or rejected guesses are counted. After that limit you receive\none final guess-only opportunity.
