The leader opens the doors

Tufa Labs says two NVIDIA GB300 NVL72 racks are live in Stockholm. Our commissioned feature above follows DELTA’s deployment film, with a timestamped guide for readers who cannot watch. The announcement puts new substance behind Tufa’s earlier compute bravado. It establishes installed capacity, without tying that installation to any particular ARC submission. Dries Smit remains on Tufa’s closing roster; the immense citadel and its spider crew are editorial fantasy.

Turducken takes third; the leading pair stays clear

Tufa closes at 68.91, with Yi-Chia Chen second at 67.49: both scores are unchanged from the previous close. Team Turducken rises from fifth to third after adding 3.90 points to reach 52.82, passing mtg and the last dance. That is a consequential reshuffle behind the leaders, although Turducken still trails Chen by 14.67 points. Grigoriy Zatravkin gains 2.17 points and closes sixth at 47.19.

The top ten and the gold chase

artificialagencylab.com closes seventh at 45.41. Its recorded score event rose from 41.74 to 45.41; the previous-close comparison is unavailable, so that event is not a verified net daily gain. 復活の混テキスト is eighth, Majkel1337 ninth and NVARC3 tenth. NVARC3’s score stays 43.94 despite losing a place. The provisional gold boundary is 37.98; Lord Han Solo remains 23rd at 37.07, below that line.

Disselhoff makes the afternoon move

Jan Disselhoff closes 45th at 34.77. The observed afternoon event took him from 770th to 45th, a gain of 5.34 points; the wire’s 734th-place comparison began in a different window. The edition has no previous-close comparison for him. Farther down, Tong Hui Kang gains 107 places against the previous close to finish 61st at 33.99. The wire also recorded Pushpak Teja, Sunstone North Lab and Fighting Gold reaching the top 100 earlier in the day; those are dated moves, not four fresh closing gains.
