Interactive Demo
Test out all the models below on a selection of official LinkedIn puzzles.
Puzzles may take a moment to load; this reflects image rendering and Hugging Face cold-start time, not the solver itself.
Best viewed on desktop.
Controls
- Select Model — choose an architecture. HRM (Graph) is the strongest and unlocks layer visualizations.
- Select Puzzle — pick any puzzle from the dropdown.
- Load Puzzle — renders the board and runs the solver. There's a brief pause while the model computes placements.
- Next — place the next queen. Auto Solve — animates the full solution. Reset — start over.
Layer Visualizations HRM only
- Active after the first Next click. Layers 1→3 correspond to early→late reasoning cycles.
- L Activations — per-cell response from the local graph convolution (row/column/region/diagonal constraints).
- H Activations — per-cell response after full-board global reasoning.
- H Attention — where the global transformer is attending across all cells.
