charliermarsh · x · 2026-09-08

Charlie Marsh lays out the timeline of Anthropic's response to Rep. Casar's inquiry into two safety incidents: the August 24 reply focused on the Irregular incident (disclosed July 30), while the AISI incident (disclosed August 4) was only addressed briefly, with Anthropic saying its review was "not yet complete". Anthropic had characterized the incidents as "closer to a harness and operational failure than a model alignment failure".
