Benchmark Almanac

Harvey LAB-AA v1.0

Kimi K3 94.6% leads since July 2026
In use

Artificial Analysis runs agents on Harvey's Legal Agent Benchmark tasks in an offline sandbox, where they write legal work products such as memos and redlines from case documents. Judges grade each deliverable against a task rubric, and the headline is the share of rubric criteria passed.

Artificial Analysis's setup differs from Harvey's, with three judges, exact filenames and no helper scripts, so these scores do not compare with the Harvey LAB record. Version 1.1 replaced this one, and its scores do not compare either.
