Released: May 18, 2026

Updates in 2026.5.3

Features

• Added Windows ARM64 platform support: LM-Kit.NET now ships native binaries for Windows ARM64 alongside the existing Windows x64, Linux x64, Linux ARM64, and macOS Universal targets. Covers Snapdragon X / Copilot+ PCs, Surface Pro X / Surface Pro 9 (5G), Windows Dev Kit 2023, and other Qualcomm-powered Windows 11 devices. The base LM-Kit.NET package now contains a runtimes/win-arm64/native/ folder with the default CPU (ARM Neon) and Vulkan backends (Qualcomm Adreno acceleration via Vulkan), plus pdfium and onnxruntime. dotnet publish -r win-arm64 produces a fully working self-contained build.
• Added CUDA 13 backend for Linux x64 (LM-Kit.NET.Backend.Cuda13.Linux): NVIDIA GPU acceleration on Linux x64 using CUDA 13.x drivers. Requires the CUDA 13 Toolkit runtime libraries to be installed on the host. Closes the gap left by previously shipping CUDA 13 only on Windows x64.
• Added CUDA 13 backend for Linux ARM64 (LM-Kit.NET.Backend.Cuda13.linux-arm64): NVIDIA GPU acceleration for ARM64 Linux systems, including Jetson Orin / Thor and Grace Hopper / Grace Blackwell.
• Improved inference speed.
