LLMs invent Japanese law articles more often when prompted in Japanese

By PulseAugur Editorial · [1 sources] ·

A new benchmark has been developed to test how well Large Language Models (LLMs) ground their answers in actual Japanese legal articles. The benchmark uses the official e-Gov Law API v2, containing over 6,900 articles, to verify citations made by LLMs. When prompted in Japanese, two out of three tested local LLMs invented legal articles more frequently than when prompted in English, suggesting a language-dependent grounding issue. AI
