The full stack, your way

When we think about work in the agentic age, it requires a ubiquitous intelligence platform that spans cloud and edge. But as a developer, how do you build these rich, agentic systems while staying firmly in control? That means staying in flow instead of waiting on tools and running experiments in minutes rather than hours. It starts at the silicon, and that’s where Surface RTX Spark Dev Box comes in – it’s designed for sustained workloads: long-running training jobs, agentic AI pipelines and local model fine-tuning. Powered by NVIDIA RTX Spark, it delivers up to one petaflop of AI compute and 128 GB of unified memory, capable of running up to 120B parameter LLMs with up to 1 million tokens context using agents locally without cloud GPU instances [3].

Windows Services for Linux (WSL) 2 with native GPU passthrough and full CUDA support comes pre-configured for developers, with Visual Studio Code, GitHub Copilot and many more of your favorite tools pre-installed. Surface RTX Spark Dev Box will be available later this year in the US via Microsoft. com. In the OS layer, Microsoft is making Windows an agent-native runtime. Microsoft Execution Containers (MXC), now in preview, gives developers and IT administrators a simpler way to create enterprise-grade sandboxed environments for agents, with containment enforced by the operating system itself.

Describe your requirements once, and Windows enforces them everywhere your agents run. This technology is now being used by OpenClaw on Windows, enabling execution of multi-step workflows inside these OS-enforced boundaries. NVIDIA’s OpenShell secure runtime for autonomous agents uses MXC and adds policy management, inference routing and PII obfuscation. Together, these capabilities give developers a safe environment for agent development and deployment and provide IT teams with the governance tools they need across local devices and cloud environments.
