The result is a capability demonstration, not an official contest medal and not a contribution of new theorems. OpenAI independently reported the same score from a separate experimental model; that is a different event. Human gold medalists still exist above and at this score. This does not count toward Net Good.","ledger_type":"capability","primary_domain_id":"23d935bb-b857-4b2b-9471-d568bb848a66","event_status":"verified","event_date":"2025-07-21T00:00:00.000Z","discovery_date":"2025-07-21T00:00:00.000Z","first_published_date":"2025-07-21T00:00:00.000Z","last_reviewed_date":"2026-10-28T00:00:00.000Z","geographic_scope":"International (IMO 2025, Australia)","affected_population":"Mathematics and AI-reasoning research communities","base_impact_tier":3,"base_score":"10.00","attribution_multiplier":"0.9000","evidence_multiplier":"0.5000","realization_multiplier":"0.5000","durability_multiplier":"0.7000","current_event_score":"1.575000","confidence_level":"high","score_explanation":"Officially graded gold-threshold IMO performance is a major capability milestone (tier 3), not Net Good.
