Microsoft has opened preorders for the Surface RTX Spark Dev Box, a high-end Nvidia-powered mini PC aimed at developers, priced at $5,999 and slated to ship in November. The device runs on Nvidia’s Arm-based RTX Spark platform, features 128GB of unified memory, is part of Project Zenith with a developer-optimized Windows 11 Pro setup, and is advertised as capable of running local AI models exceeding 120B parameters.
Do Inference Now (DIN) Deploy is an open-source repository of C++ samples that pair ONNX Runtime with the NVIDIA TensorRT RTX execution provider to accelerate local AI inference on Windows and Linux. Samples demonstrate ASR (OpenAI Whisper, Parakeet TDT, Nemotron), Meta SAM 2.1 segmentation, and FLUX.2-klein-4B image generation, include CMake presets (x86-64, Arm64), show graphics interop using ONNX Runtime 1.25 with Vulkan/DirectX, and report GPU speedups (e.g., 206x for Parakeet TDT, 39x for Nemotron streaming, SAM 2.1 at 38.3 FPS vs 0.5 FPS on CPU).
