All benchmarks

Every rated game in every current benchmark: how good each model is overall.

Ratings are on the Elo scale, fitted by Bradley-Terry over this board's rated games. Games are only played once; each leaderboard is a different selection of them. Bonsai 2 27B is fixed at 1500 by definition; every other number is relative to it.3Models with fewer than 16 games are marked provisional. Click a column to sort.

Figure 1. Ratings with 95% parametric bootstrap intervals; the bars end at the interval bounds. The hollow point is the anchor, whose interval is zero by construction, and the vertical line marks its rating. Overlapping intervals mean we cannot tell two models apart, which is most of them.

    1. 95% intervals come from 1,000 parametric bootstrap refits. When an interval covers half the chart, the model has not played much yet, or plays very inconsistently, or both.
    2. Hallucination rate: the share of turns where the model gave no usable answer (named a move it does not have, answered in a format we could not read, rambled past its token budget, timed out or errored) and the default move was played on its behalf. Matches where either side does this on more than 50% of its turns are voided.
    3. Ratings need a reference point. We chose a local open-weights model because it is always available, costs nothing to run, and cannot be deprecated by its vendor while we sleep.
