Nvidia wants to keep AI agents on a short leash with a watchdog built into its chips

Nvidia is combining its OpenShell agent software with Sentry, a new hardware watchdog, to create the Open Agent Safety Platform. Sentry is supposed to isolate AI agents that break out within milliseconds. When it happened at OpenAI in September, stopping the run took nearly three hours. Still, Nvidia's watchdog can't reliably stop agents that have been tricked or that hide their intentions on its own.
