Introducing MagenticLite ✨ We listened to the community and evolved Magentic-UI — now purpose-built for small models. To do that, we co-designed it end-to-end with two new SLMs for agentic experiences across browser + local file system: 🖱️Fara1.5 (9B) — new SOTA for small computer-use models, nearly 2x Fara-7B on web navigation. 🧠MagenticBrain (14B) — an orchestrator model that plans, codes, and delegates. GitHub update is live https://aka.ms/MagenticLite

A very important and cool release from our AI Frontiers Lab: Small agents that hit SoTA at computer use (web + GUI + local files) for a fraction of the compute.

Kinda amazing how far data work, synthetic environments, and modeling can take you!
