DiG-bench: every one of 70 games solved by a human first try, only two models cleared any Tier-7 task.

A group including Tri Dao, Jürgen Schmidhuber, Joshua Tenenbaum, Thomas Griffiths, and James Whittington encoded 70 hidden-rule discovery games as short strings where both the transformation rules and the win conditions must be inferred through experimentation (arXiv 2608.12593). All 70 solved by at least one human on first attempt. 21 public, 49 held private. Per Jack Clark's Import AI 469, Opus 5 and Fable 5 led, and only those two cleared any Tier-7 task at 0.2 success. Clark predicts human parity by mid-2027 and treats that as the gate on recursive self-improvement.
