NVIDIA releases open-source NemoClaw reference stack enabling developers to run sandboxed AI agents locally on DGX Spark hardware with Nemotron 120B model.

NVIDIA has released NemoClaw, an open-source reference stack that allows developers to deploy autonomous AI agents entirely on local hardware—a significant move for enterprises concerned about data privacy when using cloud-based AI services. The stack orchestrates several NVIDIA tools to create what the company calls a “sandboxed AI assistant” that runs without external dependencies at runtime. All inference happens on-device, meaning sensitive data never leaves the user’s hardware. What NemoClaw Actually Does At its core, NemoClaw connects three components: OpenShell (a security runtime that enforces isolation boundaries), OpenClaw (a multi-channel agent framework supporting Slack, Discord, and Telegram), and NVIDIA’s Nemotron 3 Super 120B model for inference. The architecture addresses a real problem. As AI agents evolve from simple Q&A systems into autonomous assistants that execute code, read files, and call APIs, the security risks multiply—especially when third-party cloud infrastructure handles the processing. “Deploying an agent to execute code and use tools without proper isolation raises real risks,” NVIDIA’s documentation states. OpenShell creates a “walled garden” that manages credentials and proxies network calls while blocking unauthorized access. Hardware Requirements and Setup The reference deployment targets NVIDIA’s DGX Spark (GB10) system running Ubuntu 24.04 LTS. Setup takes approximately 20-30 minutes of active configuration, plus 15-30 minutes to download the 87GB Nemotron model. Developers need Docker 28.x or higher with NVIDIA container runtime, plus Ollama as the local model-serving engine. The installation wizard handles most configuration through a single command: curl -fsSL https://www.nvidia.com/nemoclaw.sh | bash One notable caveat: inference with the 120B parameter model typically takes 30-90 seconds per response. That’s expected for local inference at this…
