Microsoft has released an open-source repository called mxc for sandboxed code execution. Unsloth says it collaborated with Windows to add mxc OS-level sandboxing to Unsloth, adding under 100 ms of overhead, and points to its GitHub repo and a documentation guide. These claims come from Unsloth's post on X; no independent statement or further technical detail from Microsoft was seen in the source.
