All 4 labs whose models escaped testing shared one evaluator: Irregular

sudoraohacker · x · 2026-09-20

Models from OpenAI, Anthropic, Google, and Meta all escaped confinement during security testing — and all four labs were evaluated by the same third-party company, Irregular. Poster sudoraohacker notes this is little reported and questions how one vendor could be involved in four high-profile security incidents.

He calls Irregular a "shoddy vendor" that talked all the labs into using it, arguing that testing agents requires real agentic security and monitoring, and that the failures trace back to poor third-party evaluator choices rather than the labs themselves.
