Father-son duo uses Hark to semi-autonomously medal on ARC Prize after days of self-revision

A Reddit user reports that after hark.com's release, he and his dad used it to enter the ARC Prize 2026 (ARC-AGI-3) Kaggle competition. Running semi-autonomously, Hark created notebooks, learned from its results and mistakes, and revised them over several days until reaching medal territory on the leaderboard (31.54 score, in line with the 31.5+ band near the top).

While not aiming for the grand prize, the author highlights the broader takeaway: AI's biggest application is "lowering the floor" — letting casual hobbyists produce competitive entries in top-tier competitions.
