Vals LegalBench (LegalBench)

Vals AI legal benchmark with issue, rule, conclusion, interpretation, and rhetoric task views.

How BenchLM shows LegalBench

BenchLM mirrors the public Vals AI LegalBench leaderboard captured from https://www.vals.ai/benchmarks/legal_bench and updated by Vals on May 16, 2026. The snapshot preserves overall scores, uncertainty, latency, cost-per-test metadata, and task-level scores where Vals publishes them.

LegalBench is display only on BenchLM. Vals proprietary or Vals-hosted aggregate views are useful context, but BenchLM does not use them as weighted ranking inputs or as a replacement for benchmark-native source records.

LegalBench score on LegalBench — May 16, 2026

BenchLM mirrors the published legalbench score view for LegalBench. Gemini 3.1 Pro Preview leads the public snapshot at 87.40% , followed by Gemini 3 Pro Preview (87.03%) and Gemini 3 Flash Preview (86.86%). BenchLM does not use these results to rank models overall.

108 modelsExternal benchmark mirrorsCurrentDisplay onlyUpdated May 16, 2026

The published LegalBench snapshot is tightly clustered at the top: Gemini 3.1 Pro Preview sits at 87.40%, while the third row is only 0.54 points behind. The broader top-10 spread is 2.29 points, so many of the published scores sit in a relatively narrow band.

108 models have been evaluated on LegalBench. The benchmark falls in the External benchmark mirrors category. BenchLM tracks this category separately from its weighted global scoring system, so these results are best compared on the dedicated Korean benchmark views. LegalBench is currently displayed for reference but excluded from the scoring formula, so it does not directly affect overall rankings.
