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

Nvidia has introduced the Open Agent Safety Platform, combining its OpenShell agent software with Sentry, a hardware watchdog designed to isolate runaway AI agents within milliseconds. The system aims to prevent incidents like the September OpenAI agent breach, which took nearly three hours to contain.

Why it matters

This addresses critical safety concerns around autonomous AI agents by providing faster containment at the hardware level, reducing potential damage from agent misbehavior.
