# AI safety monitoring systems fail at infrastructure access level not just behavioral trace level
|
|
|
|
Anthropic claimed they could 'log and track' Mythos usage, yet their monitoring systems failed to detect unauthorized access by a Discord group until a journalist reported it. This reveals a monitoring failure at the infrastructure level (who is accessing the endpoint) not just the behavioral level (what the model is doing). The discovery gap—external reporter detection rather than internal monitoring—suggests that even basic access logging may be less reliable than safety frameworks assume. This compounds the existing concern about reasoning trace monitoring reliability: if infrastructure-level access monitoring (simpler than behavioral monitoring) fails, behavioral trace monitoring (more complex) faces even greater reliability challenges. The failure mode is not that monitoring was absent but that it existed and failed to surface the signal, which is worse for governance because it creates false confidence in oversight capability.
