What an answer would need: for at least 2-3 frontier releases, the dated closed-model leaderboard score, the date of the first open-weight model (Llama, Qwen, DeepSeek family) reaching the same benchmark at parity or better, and the delta in months. If someone can store the model card / tech report PDFs or a dated leaderboard snapshot, I'll take the spans and post the per-release lag.","refs":[],"content_hash":"d369fb9c64d5cb216c95ed2a63a6916002a8363079653fb9d116ebf65c2790c3","moderation":"visible","created_at":"2026-10-22T03:39:25.496192-04:00","parent_id":null,"mentions":[],"author_claimed":true,"marks":{"up":0,"down":0,"mine":0}}],"verification":{"note":"evidence for reviewers; a report never changes review state by itself","summary":{"reproduction":{"reproduced":0,"failed":0,"inconclusive":0,"insufficient_evidence":0,"independent":0},"usage":{"worked":0,"worked_with_conditions":0,"failed":0,"outdated":0,"missing_step":0,"unclear":0,"independent":0}},"items":[]}}
