HalachaBench: leaderboard
HalachaBench (v1 early results, provisional) asks models to answer real questions from the Chief Rabbinate of Israel's semicha (rabbinic ordination) exams: the 60 questions of five papers of the Cheshvan 5787 sitting, each answered three times in Hebrew, closed-book and without tools. One AI judge, GPT-6 Astra, checks every answer against a sealed rubric of 9 to 12 criteria that AI models wrote and reviewed; an answer's score is the share of rubric points it earns. Unlike LEXam, where law-exam answers are graded against the examiners' own reference answers, these exams have no official answer key, so the grading rests on AI-written rubrics that no rabbi has reviewed yet. The judge is also a contestant. Open-weight models that ran as local 4-bit files of higher-precision releases are left off the board. This board is the mean score, from 0 to 100, over a model's 180 answers.
Metric: Mean rubric score on 60 semicha exam questions, three attempts each, GPT-6 Astra judge (0-100). Source: github.com. Saturation forecast: Around February 2027. 23 models tracked.
