There is no systematic unfair advantage over the humans described in the Human Performance section (e.g. AI systems are allowed to have multiple outputs autograded while humans aren't, or AI systems have access to the internet when humans don't).\n\nHuman cost parity. Having the AI system complete the task does not use more compute than could be purchased with the wages needed to pay a human to complete the same task to the same level. Any additional costs incurred by the AIs or humans (such as GPU rental costs) are included in the parity estimation.\n\nThe PASS@k elicitation technique (which automatically grades and chooses the best out of k outputs from a model) is a common example that we do not accept on this benchmark because human software engineers do not have access to automatic grading of their solutions, so PASS@k would constitute an unfair advantage.\n\nIf there is evidence of training contamination leading to substantially increased performance, scores will be accordingly adjusted or disqualified.\n\nIf a model is released in 2026 but evaluated after year-end, the resolver may include it at their discretion (if they think that there was not an unfair advantage from being evaluated later, for example the scaffolding used should have been available within 2026).\n\nEli Lifland is responsible for final judgment on resolution decisions.\n\nHuman cost estimation process:\n\nRank questions by human cost. For each question, estimate how much it would cost for humans to solve it. If humans fail on a question, factor in the additional cost required for them to succeed.\n\nMatch the AI's accuracy to a human cost total. If the AI system solves N% of questions, identify the cheapest N% of questions (by human cost) and sum those costs to determine the baseline human total.\n\nAccount for unsolved questions. For each question the AI does not solve, add the maximum cost from that bottom N%. This ensures both humans and AI systems are compared under a fixed per-problem budget, without relying on humans to dynamically adjust their approach based on difficulty.\n\nBuckets are left-inclusive: e.g., 4-4.5 months includes 4.0 but not 4.5.","image":null,"icon":null,"active":true,"closed":false,"start_date":"2026-01-16T20:49:25.363000Z","end_date":"2027-01-01T04:59:59Z","closed_time":null,"volume":44004.40079575599,"volume_24hr":0.0,"volume_24h_change":null,"normalized_vol_24hr":null,"normalized_volume":42.91374206542969,"liquidity":10000.0,"open_interest":null,"categories":["Science
