PADM\'E: Preference Alignment Data Synthesis for Meta-Evaluation of LM Agent Evaluators

PADM'E is a method for synthesizing preference‑aligned data to meta‑evaluate language‑model (LM) evaluators of agentic behaviors. It reframes meta‑evaluation as a preference judgment problem, generating criterion‑based data with small LMs and no human involvement. In a prototype, PADM'E produced 1,000 samples across four domains and three criteria, and human validation showed agreement with human judgment rising from 73% to 85% compared to a naive baseline.

Personalized RewardBench: Evaluating Reward Models with Human Aligned Personalization

arXiv:2604. 07343v2 Announce Type: replace-cross Abstract: Pluralistic alignment has emerged as a critical frontier in the development of Large Language Models (LLMs), with reward models (RMs) serving as a central mechanism for capturing diverse human values.

Evaluating Criterion-Conditioned Behaviour of Large Language Models in Content Moderation

The paper introduces DECO, a diagnostic framework that factorises content into independent moderation criteria, allowing controlled evaluation of large language models (LLMs) at the criterion level. Using pairwise evaluation across four datasets and four LLMs, the authors find that high aggregate benchmark scores can mask significant failures when decisions hinge on specific content aspects required by individual criteria. The study underscores that aggregated labels do not guarantee reliable criterion-conditioned performance, highlighting the need for evaluation methods that explicitly assess this behavior.

DualEval: Joint Model-Item Calibration for Unified LLM Evaluation

arXiv:2606. 26429v1 Announce Type: new Abstract: Current LLM evaluation relies on two complementary but often disconnected signals: static benchmarks with objective correctness labels and arena-style preference data that better reflect open-ended user interactions.
