Microsoft and academic researchers want to give AI models a new kind of home: the AI Model Virtual Machine (MVM). Think of it like the JVM, but for LLMs—an interface layer that standardizes how models plug into host software.

The MVM enforces security, isolation, and tool-calling rules, while also unlocking interoperability through protocols like MCP and access frameworks like AC4A and FIDES.

Big picture: This is a shift toward treating LLMs less like magic black boxes and more like proper runtime components—bounded, controllable, swappable. Like OS processes, but weirder.
