DeepMind researcher finds Kimi 3.1 Pro strong on benchmarks but weak in a real test

DeepMind researcher Samuel Albanie shared a mixed first impression of Kimi 3.1 Pro: on a moderately hard prompt asking for benchmark-based visualizations to estimate the China-vs-West frontier AI gap, the model performed poorly — despite spending roughly two hours reasoning.

He caveats the sample size of 1, noting the model looks very strong on public benchmarks and he's keen to see others' reactions.
