DeepLearning.AI: Meta's Muse agent builds prompt injection defenses at the OS level

DeepLearning.AI argues that prompt injection defenses should not rely solely on a model's own training. In a post about Meta's Muse agent, it says the system assumes the model will be tricked and instead builds security at the OS level.

According to DeepLearning.AI, the model never handles real credentials, tools run in isolated Linux containers, and an independent gatekeeper verifies outbound calls. It linked a fuller analysis at https://hubs.la/Q04xZx500.
