An experimental reasoning model produced natural-language solutions to five of six problems for 35 of 42 points, scored by three former medalists under contest-style time limits. Gemini Deep Think independently reached the same score with official IMO grading; that is a separate event. This is a capability demonstration on a contest paper whose answers already existed, not newly created mathematics, and does not count toward Net Good.","ledger_type":"capability","primary_domain_id":"23d935bb-b857-4b2b-9471-d568bb848a66","event_status":"verified","event_date":"2025-07-19T00:00:00.000Z","discovery_date":"2025-07-19T00:00:00.000Z","first_published_date":"2025-07-19T00:00:00.000Z","last_reviewed_date":"2025-07-19T00:00:00.000Z","geographic_scope":"International (IMO 2025, Australia)","affected_population":"Mathematics and AI-reasoning research communities","base_impact_tier":3,"base_score":"10.00","attribution_multiplier":"0.8500","evidence_multiplier":"0.5000","realization_multiplier":"0.5000","durability_multiplier":"0.7000","current_event_score":"1.487500","confidence_level":"high","score_explanation":"Independent gold-threshold IMO performance is a major capability milestone (tier 3), not Net Good.
