Blogger patiencecave tested Kimi K3.1 Pro on MazeBench, a spatial-reasoning maze benchmark. The model solved a multistep puzzle after 20 attempts — only 5 other models have managed this before. It showed clear exploration gains over the previous Kimi K3, but stalled on concave blocks and could not progress further. Screenshots compare the two models' maze exploration traces.
