11.67% ARC-AGI-2 Local Eval on a Single 4090: The TOPAS Recursive Architecture

Doug_Bitterbot says TOPAS scored 11.67% on ARC-AGI-2 using one RTX 4090 after about 14 days of training. The 100M-parameter checkpoint hit 36% locally, but recursive TTT caused null outputs on nearly half of Kaggle puzzles. The key detail is time management: the author expects 20% after threshold tuning and 3-5 more weeks of training.

Why it matters: HKR-H/K/R all pass, but this is a single Reddit post with unstable Kaggle submissions. It clears featured, not the higher research-release band.
