Meta now has the most insane AI agent

Meta's AI agent represents a shift from large language models to large action models (LAMs) that can interact with computers through visual understanding and mouse/keyboard control. The system uses vision transformers to parse screen pixels, DOM annotation for web interaction, and operates in ephemeral sandboxed microVMs for security. By working at the UI layer rather than requiring APIs, it enables probabilistic automation of complex workflows across legacy systems, marking a transition from text-to-text models to multimodal input-to-executable-action systems.
