DeepSNR CLI tools
Download standalone DeepSNR CLI packages here. PixInsight users
should use the DeepSNR repository
so PixInsight can keep the module updated.
Choose between two download formats:
- Installer: sets up the tool and its support files
in the standard installation location.
- ZIP: a portable archive for manual setup. Extract all
files and keep the supplied folder layout. Extracting a ZIP does not
run an installer or automatically add the tool to PATH.
If you are unsure which one you need, choose the installer
for your operating system. Both formats provide the same command-line
tool; neither adds a graphical interface. See the
FAQ for more about installation and running
the tool from a terminal.

Windows
DeepSNR CLI for Windows 1.3.2-0147 ORT x64 Released 2026-09-19 273.3 MB
Current Windows DeepSNR CLI package with DirectML support and CPU fallback.
Windows CLI packages include ONNX/ORT with DirectML support. They use the DirectML library supplied by Windows, normally located at C:\Windows\System32\DirectML.dll; we do not bundle that DLL. GPU acceleration also requires a compatible DirectX 12 GPU and driver. If DirectML initialization fails, the tool falls back to CPU. Keep Windows and your GPU driver updated; see the Windows GPU instructions for requirements and troubleshooting.
System requirements
- Requires 64-bit Windows 10 or Windows 11.
- Windows ONNX/ORT packages support DirectML acceleration with CPU fallback when DirectML is unavailable.
- ONNX/ORT with DirectML support is included; DirectML.dll is supplied by Windows, not bundled. GPU acceleration requires a compatible DirectX 12 GPU and driver.
