HRM paper: 27M params, 1000 samples, near-perfect Sudoku and maze solving

burny_tech · x · 2026-11-10

The quoted post links the HRM paper (arXiv:2506.21734): a brain-inspired recurrent architecture with a slow abstract-planning module and a fast detailed-computation module that reasons in a single forward pass without CoT data. With only 27M parameters and 1000 training samples it nearly perfectly solves complex Sudoku and optimal maze pathfinding, and beats far larger models on the ARC benchmark.
