Microsoft open-sources MagenticLite, MagenticBrain 14B and Fara 1.5
ZacharyHuang12 · x · 2026-07-23
Microsoft says MagenticLite is now fully open source, with the whole stack released on Hugging Face: the MagenticBrain 14B orchestrator, the Fara 1.5 computer-use family, the app, and the harness.
The release positions the stack as an agentic system rather than a single model. Microsoft highlights:
- MagenticBrain: a 14B orchestrator
- Fara 1.5: 4B / 9B / 27B computer-use models
- MagenticLite: the application layer for browser and file-system tasks
