Big tasks. Small models.

MagenticLite is the next generation of Magentic-UI — an agentic application from Microsoft AI Frontiers, redesigned to do more with less. It pairs an on-device-friendly orchestrator model (MagenticBrain) with a specialized browser-use model (Fara) so you can automate real work without depending on frontier-scale compute.

• Built for small models, efficient by design. Strong agentic performance without heavy compute — no frontier-scale models required.
• Works across the browser and your local file system. Web research, form filling, file management — in one workflow.
• Keeps you in the loop and in control. Steer, approve, or take over at any point. MagenticLite stops and checks in before taking critical actions.
• Safe by design. Browser sessions run inside a lightweight VM sandbox (Quicksand) so the agent can't reach the rest of your machine without your say-so.
