Harvey LAB-AA v1.1 Benchmark Leaderboard
v1.1 の変更点
v1.1 は v1.0 を置き換えるもので、バージョン間でスコアは比較できません。Harvey が法律専門家と行った調査では、幻覚が弁護士がどの出力を好むかを左右する主要な要因であることがわかりました。そこで Harvey と協力し、採点に幻覚チェックを追加しました。
- タスクと基準を改善した、Harvey の最新の非公開データセット
- すべての成果物をタスクのソース文書と照合する新しい幻覚チェック。重大な幻覚は採点でペナルティを受けます
- 採点者を GPT-6 Sol、Grok 4.7、Claude Opus 5.5 に更新しました。自己選好はごくわずかでしたが、偏りを抑えるため3つの結果を平均します
