InsufficiencyBench: Evaluating LLM legal advice on underspecified user queries
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- InsufficiencyBench is a legal benchmark testing whether LLMs recognize when user queries lack material facts needed for accurate legal advice.
- Why it matters
- Matters for engineers building legal AI systems, especially those deployed to answer real user questions where critical details are often missing.
- Watch out
- No current frontier model exceeds F2 score of 0.46 on identifying missing elements; models either over-hedge or answer based on false assumptions.
