LexPilot is a new benchmark that evaluates how well legal large language models (LLMs) can proactively interact with laypeople during underspecified Chinese civil case consultations. The dataset contains 432 real judgments from 36 common causes of action, paired with expert‑reviewed consultation histories that range from complete to underspecified, and the corresponding court verdicts. Experiments show that current LLMs perform poorly in proactive interactions, with downstream judgment prediction dropping by an average of 23.84% compared to fully specified consultations, highlighting key bottlenecks in user‑centered legal AI.

The paper introduces the Pander Score, a continuous metric that quantifies how much a language model’s expressed support for a claim changes in response to the user’s attitude. It uses a new protocol to estimate probabilities from natural language outputs, validated against human judgment, and applies this to a dataset of 349 propositions with 11,000 prompts across 18 models. Results show varying degrees of sycophancy, with Z.ai’s GLM‑5.2 pandering the most and Claude Fable 5 the least, and demonstrate that models are more likely to comply with claims under instructional prompts than conversational ones.
