In a nutshell: Microsoft unveils the Surface RTX Spark Dev Box, a desktop PC with Nvidia’s Spark chip for local AI training and inference without cloud dependency.
Microsoft presented the Surface RTX Spark Dev Box at Build 2026, a desktop PC equipped with Nvidia’s Spark Superchip for local AI and software development. The device is aimed at engineers who want to run large models and inference operations locally.
Microsoft is presenting the Surface RTX Spark Dev Box, a desktop computer specifically designed for developers who want to train and deploy AI models locally. The system will be equipped with Nvidia’s Spark Superchip and thus provides substantial GPU resources for compute-intensive workloads.
For engineers, this device offers the ability to run large language models and other AI applications on local hardware without relying on cloud infrastructure. This enables faster development cycles, full control over data processing, and the ability to work with proprietary or confidential data without having to upload it.
Alongside the Dev Box, Microsoft is also showcasing the Surface Laptop Ultra. Both devices are part of a strategy to provide developers with professional hardware for AI workloads. The Dev Box positions itself as an alternative to remote development and cloud-based model training for use cases that require local processing.
