LisanBench
Models build the longest chain of distinct English words from a given start word, each differing from the last by one letter. The score sums valid chain lengths over all start words.
Three trials per start word, averaged. A difficulty-weighted score gives common words less weight. The site also tracks reasoning tokens and full-run cost. Tokenization affects letter-level tasks like this one.

Muse Wonder Full leads with 37152.2
Best score per entry from the benchmark's own leaderboard, read on November 12th, 2026. Where a model ran with several settings or harnesses, we keep its best. Every run is in the next chart. Names in gray aren't in our model list: fine-tunes, agent systems, products and older models. They don't count toward leaders.

Reasoning Tokens vs Path Length
Path Length against the average reasoning tokens per trial, on a log scale; runs without reasoning sit at zero. The line joins the runs that no other run beats on both measures. We redrew this chart from the numbers on the official leaderboard.
