A second advance takes ibyyue into the top ten

ibyyue reaches tenth on 65.56 after a second recorded improvement, from 56.81 earlier today. The Early edition had covered its move into provisional gold; this later advance takes it past ARC Raiders, now eleventh on 65.00, and Arcnights, twelfth on 64.17. The full previous-close comparison for ibyyue is unavailable, so the latest score event should not be mistaken for its whole daily gain. Tufa Labs remains first on 88.06, ahead of Yi-Chia Chen on 83.89 and rabbithole on 80.56, all unchanged since the previous close.

A stronger score can still cost a place

Arcnights has gained 15.42 points and five places since the previous close, yet finishes one place below the eleventh reported in the afternoon special. ARC Raiders has added 0.42 points and still slipped two places to eleventh. Majkel1337 holds seventh on 68.19 after its recorded rise from 62.08. The provisional gold score is now 55.00, up from 53.06 at the previous close; masspeaks occupies fifteenth exactly on that score. Osaka Metropolitan University’s 大阪公立大学 shiiin9 is eighteenth on 52.08 after a 6.25-point daily gain. Improvement alone does not secure a place when the field advances too.

The wider chase

Daniel Franzen’s 16.81-point score event took him to 46.67 and twenty-first when first recorded this afternoon; that is a dated observation rather than a fresh closing-rank claim. The same afternoon wire recorded Ravi Teja Chilakala reaching 40.69. Elsewhere, Ryo Takaki closes twenty-seventh on 43.47, up 185 places and 11.25 points since the previous close. Odd Dice is thirty-second on 42.08 after a three-point daily improvement. These separate entries show how much movement continues beyond the gold line; none of these gains establishes a method or a new team formation.

A separate benchmark headline

ARC Prize’s Argon announcement reports 91.3% on ARC-AGI-2 at $0.32 per task. This is a Verified model evaluation, not a Kaggle submission, so it does not displace Tufa from the competition lead. The afternoon special documented a discrepancy between the results page’s introductory figure and its table; this edition attributes 91.3% specifically to the organizer’s announcement. Public competition positions remain provisional.
