FAQ

Purpose

This page answers common questions about XAI OS.

Is XAI OS a Linux distribution?

No. XAI OS is not a Linux distribution.

Is XAI OS a BSD fork?

No. XAI OS is not a BSD fork.

Does XAI OS use GPUs?

No GPU is required. XAI OS targets CPU-only AI and has no CUDA, Metal, or GPU acceleration dependency.

Why CPU-only AI?

CPU-only AI is deployable on ordinary servers and appliances, avoids vendor GPU runtime dependency, and lets the OS control cores, memory placement, networking, and build/test work in one resource model.

Can XAI OS really beat Linux/BSD?

Only measured results can answer that. XAI OS has design targets for a narrow workload: CPU-only embedded app agents with explicit core ownership, memory arenas, and low-latency networking. It should not claim broad superiority over Linux/BSD.

What does near-zero migration mean?

It means hot AI workers should remain on their leased cores unless the service explicitly changes placement.

Why start with QEMU on macOS?

QEMU on macOS gives a reproducible correctness target for boot, memory, devices, and kernel basics. It is not a performance target.

Why Intel Desktop before Xeon?

Intel Desktop is accessible and exposes real P-core/E-core, NVMe, NIC, and sustained-performance behavior before the complexity of NUMA servers.

Why ARM/NVIDIA last?

ARM/NVIDIA N1X-compatible work needs the OS architecture to be stable before AArch64 boot, GIC, SMMU, and cluster policies are added.

What language will XAI OS be written in?

Early kernel code should be freestanding C99 plus minimal architecture assembly. C++ is allowed in userspace, runtime, and AI components.

Can apps still use C/C++?

Yes. XAI OS should support static C/C++ services early.

Can apps use C/C++?

Yes. This is the same policy as above: C and C++ are expected for early userspace, runtime, and application services.

Will Swift be supported later?

Possibly, but Swift is not an early kernel or bring-up requirement.

How will Git/code-changing agents be kept safe?

Through explicit permissions, scoped workspaces, build/test sandboxes, diff review, signed updates, audit logs, and rollback.
