A new leader at the front

Yi-Chia Chen took first in ARC-AGI-3 when a recorded score rose from 55.77 to 59.17. Tufa Labs also improved, from 55.89 to 56.52 in a later recorded event, but sits second. Majkel1337 holds third at 42.66. The public lead is Chen’s for now; the morning board does not tell us which submissions still await evaluation.

A shake-up behind third

NVARC3 made the sharpest move near the leaders: its recorded score climbed from 37.51 to 40.97 as it moved from ninth to fourth. SparseTech traveled farther up the order, from 391st to tenth on a rise from 29.33 to 37.98. Those are observed score events, not a claim about each team’s net change across the full overnight window.

The last dance 🕺 is fifth at 39.30, followed by dreach.ai at 39.11, artificialagencylab.com at 38.62, mtg at 38.33 and 復活の混テキスト at 38.15. Lord Han Solo is twelfth at 36.61; David Hartmann sits 336th at 29.83. With the top ten reshuffled and morning evaluations still open, the next published scores can change the order again. Public medal bands remain provisional.
