It's very cool that Apple shipped a 20B parameter on-device. You can't put 20B parameters in RAM at any reasonable precision. To make it work they are using pretty exotic architecture by today's standards.A small model predicts from the query (or prompt) which experts to load… pic.twitter.com/Zhe5HcbGuL— Awni Hannun (@awnihannun) June 9, 2026
We rebuilt the Linux microVM stack on Apple Silicon
Firecracker needs KVM and therefore a Linux host, and the image tooling around it needs loop mounts and Linux userland. We rebuilt the stack on Apple's Virtualization.framework to boot the same OCI images as microVMs on macOS and on Linux.
