BitNet on Windows

Build and run Microsoft BitNet on Windows with Visual Studio tools and conda

Windows builds of native LLM stacks are sensitive to compiler environment. BitNet is no exception: you need the correct Visual Studio developer shell, a working Clang, and CMake before Python steps from installation.

Recommended layout

  • Install Visual Studio 2022 (or newer) with C++ desktop workload.
  • Use conda for Python 3.9 as described in getting started.
  • Open x64 Native Tools or run VsDevCmd / Enter-VsDevShell so clang resolves correctly.

Verify Clang

Run clang -v. If the command is not found, your shell is not initialized for MSVC/Clang—see the detailed Command Prompt and PowerShell snippets in our FAQ (Windows Clang section).

GPU on Windows

If you target NVIDIA GPUs, install drivers and a CUDA version compatible with your BitNet checkout, then follow CUDA setup. Mixed driver/toolkit combinations often surface as cryptic link errors.

After a successful build

Download a GGUF model per Hugging Face guide and run inference. For errors, start with troubleshooting.
