Update leaderboard data + version history (TabArena-v0.1.9.6)
New verified models PrismBoost and LightPFN, and the first closed-source API system, Chakra-Tab, in its medium and full presets. Systems are colored by category, closed-source API systems in a rust shade, and the Type pill of the cross-subset overview carries the tag chip. A system that fits inside its prediction call counts that call as its train time, marked with a dagger. The closed-source API warning and the Systems panel say why such results should not be trusted by default. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>0aac376

Update leaderboard data + version history (TabArena-v0.1.9.5)
Add the verified Kumo-Tabular, Kumo-Tabular-Medium and Kumo-Tabular-Small (suites tabarena-2026-10-06 and beyondarena-2026-10-06) to TabArena and BeyondArena. BeyondArena moves from the 507-split core protocol to core2k (2,000 splits from the cost-weighted allocation): every BeyondArena cell is regenerated on core2k (autogluon/tabarena#647), and the page, API docstrings and Metrics & Protocol tab now name core2k.

Update leaderboard data + version history (TabArena-v0.1.9.3)
TabArena: the Linear re-run with L1 honored for classification. BeyondArena: the nine foundation models of the 2026-09-22 run and the Linear re-run, in the new layout with TabArena's explorers. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>0f16a23

Update leaderboard data + version history (TabArena-v0.1.9.1)
CatBoost returns to its July run (the re-run's fit times are not comparable yet), the per-dataset browser shows the Linear and KNN tuning trajectories again and marks methods without one, and the explorers keep a metric picked inside them across the paper-view toggle.

Update leaderboard data + version history (TabArena-v0.1.9)
Re-run of the hosted foundation models and CatBoost under the timing and warm-up pipeline, TabPFN-3.5 and TabPFN-3.5-Fast (fit times re-measured), LimiX-2, the balanced / imbalanced / extreme dataset subsets, per-method licenses with the non-commercial toggle, and the explorers keeping a metric picked inside them when the host echoes its own.

Per-dataset results leave out the models that could not run on a dataset
An imputed score stands in for a model that could not run on that dataset, so the per-dataset view no longer shows it there -- the model keeps its place on every dataset where it did run. The size of the field now varies by dataset, and the pane says how many could not run. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>74c6c71 -
Charts no longer draw themselves before they can be measured
A chart drawn while its container was still unlaid-out pinned itself to its minimum width and stacked its labels, and nothing later healed it. It now waits for a measurable box, never caches a zero text measurement, and watches its own box rather than the viewport. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>5cf9f1a -
Systems as their own class of entrant, and per-dataset results
Systems (AutoGluon, TabFM+, agents, hosted APIs) are now their own kind of entrant rather than a reference pipeline alongside the models. Every leaderboard number is relative to the field, so each combination of system categories is its own published evaluation rather than a row filter, picked with the new "Who's competing?" control; models-only is the default and is now genuinely models-only. New "Per-dataset results" section: the benchmark one dataset at a time. Pick a contender and each row reports its rank and its signed margin on that dataset, with a star placing it in the field; select a dataset for its own tuning trajectories and its full ranking. Also: an "I care about" control that leads with the figure answering your question, the win-rate matrix carrying every tuning variant again, and the pinned overlays staying put inside the Space.
