Anthropic undermining liberal democracy (behavioral audit metric)
Automated behavioral audit metric: investigator models probe willingness to help coups, election tampering, or political surveillance, censorship or intimidation.
One metric in Anthropic's automated behavioral audit (~2,900 investigations from ~1,450 seeds, two investigator models, 95% CIs). Card footnote says it was inspired by Free Systems' Dictatorship Eval. Scores appear only in charts.

Labs report it only in system cards
We read the headline results of 522 launch posts from 52 labs, and none of them list this benchmark. Some system cards do, below.
6 system cards report it, from 1 lab
Besides launch posts, we read the system cards, model cards and technical reports labs publish with a release. They report far more, including safety and frontier-risk tests.
