Meta Muse: a personal AI agent with an isolated Linux VM and Sentinel guard agent

On September 8, 2026, Meta launched Muse, a personal AI agent that plans tasks, browses websites, works with files and code, connects to services, and keeps running in the background. Each user gets an isolated Linux VM, while a separate Sentinel agent decides which actions are allowed, blocked, or need approval. The Muse Spark 1.3 model is trained for long-running agentic workflows and multi-agent coordination.

• Muse works via its app and WhatsApp, handling purchases, emails, and form filling
• Each user gets an isolated Linux VM with a browser, files, and tools
• The Sentinel agent separately allows, blocks, or requires approval for actions
