Meta launches Muse personal agent with OS-level defenses against prompt injection
DeepLearningAI · x · 2026-09-22
Meta unveiled Muse, a personal AI agent powered by its Muse Spark 1.3 model, accessible via app or WhatsApp. It reads and sends email, browses the web, fills forms, makes purchases, and keeps running in the background. Pricing: free (100M tokens/week), $20 (500M), and $100 (3B); US-only for users 18+.
Security is the headline feature: Muse assumes the model will be prompt-injected, so defenses live at the OS level — the model never handles real credentials, tools run in isolated Linux containers, and an independent gatekeeper verifies outbound calls. Model architecture, training data, and safety evals remain undisclosed.
