New BMMS metrics show GPT-4o failing OpenAI's Model Spec

A new research paper introduces the Behavioral Misalignment Metric Suite (BMMS) designed to evaluate language models based on specific policy compliance rather than general behavioral dimensions. The suite includes metrics like the Compliance Attainment Score (CAS) and Compliance Robustness Margin (CRM) to assess how well models adhere to defined rules. In testing, GPT-4o demonstrated a significant failure rate (70.7%) on OpenAI's Model Spec, while Claude models showed much lower failure rates. AI

IMPACT Introduces a new framework for evaluating LLM policy compliance, potentially impacting how regulated industries assess AI safety.

    BMMS: Policy-Conditioned Measurement of Behavioral Compliance in Language Models

    arXiv:2611.09147v1 Announce Type: cross Abstract: Behavioral evaluation of language models fixes its dimensions in advance: hallucination, sycophancy, toxicity, over-refusal. An operator in a regulated industry needs a different question answered: does a system do what a particul…
