No The value is a research benchmark that measures model probability calibration on scenarios with exactly computable ground truth. Designing those scenarios and the probability-quality methodology requires research expertise in probability and evaluation, which vibe coding cannot substitute for.
What it would actually take: Reproducing it requires designing natural-language scenario generators whose true outcome probabilities can be computed exactly, which means probabilistic modeling expertise, plus an evaluation harness that runs many LLMs and computes KL divergence and cost. The hard part is the methodology and the ground-truth construction, which need an ML research team and a stated theory of what a 'true' probability means here.
