Kimi K3.1 Pro reportedly first Chinese model to solve 20x20 nonograms

A Reddit user ran the nonobench (nonogram-based LLM reasoning benchmark) on Kimi K3.1 Pro, claiming it's the first Chinese model known to solve 20x20 nonograms.
- 5x5: 10/10 correct, 43s average per puzzle
- 10x10: 9/10 correct (90%), 4.9 min average, 21K tokens per puzzle
- 15x15: 5/10 correct (50%), 10 min average, 43K tokens
- No hard failures across 30 puzzles; total cost $6.75 and 671K tokens
Accuracy and speed degrade sharply with puzzle size, but the result highlights strong long-chain spatial reasoning for the Moonshot model.
