LongJud-Bench - Issue Spotting: leaderboard
LongJud-Bench (LegalWorld, Zuo et al., 2026) makes a model the target lawyer in a simulated Chinese civil case, from client consultation to second-instance trial, with every other role played by Qwen3.5-Plus on a 100-case split. Issue spotting is the consultation-stage capability: a Claude Sonnet 4.6 judge scores each answer to the client's legal questions against a reference on legal relationship, applicable rules, risk explanation and actionable advice (0-10 each), normalized to percent; higher is better.
