Microsoft unveils Magentic: AI agent stack for smaller models
Microsoft has introduced a new AI agent system called Magentic, made up of MagenticLite, MagenticBrain, and Fara1.5. This system may allow smaller models (4B-27B parameters) to do tasks in browsers and file systems that used to need much larger models. The models work together for planning, acting, and securing user data, all inside a safe sandbox. Early reports suggest the 9B Fara1.5 model reaches about 65 percent success on a benchmark, and the system is available for developers but might still be in pilot stages for wider use.
