What changed with NVIDIA Agent Toolkit
On May 31, 2026, at GTC Taipei, NVIDIA announced new Agent Toolkit software for enterprises building long-running agents: updated NemoClaw blueprints that connect popular agent harnesses, the OpenShell secure runtime for policy and privacy controls, and CUDA-X libraries such as cuDF, cuOpt and NeMo exposed to agents as skills. NVIDIA said NemoClaw was available and OpenShell was in early preview. Cadence, Dassault Systèmes, Siemens and Synopsys are using NemoClaw to build simulation and verification agents.
NVIDIA also announced Nemotron 3 Ultra, a 550-billion-parameter mixture-of-experts model post-trained for agent harnesses including OpenClaw, OpenHands, OpenCode, LangChain Deep Agents and Hermes Agent. Its Hugging Face model card lists a June 4, 2026 release, 55 billion active parameters, up to 1 million tokens of context and the OpenMDW 1.1 license, with a minimum of eight B200-class GPUs. NVIDIA also said it is working with Microsoft on Windows security features for agents, and that SAP and ServiceNow have integrated OpenShell.

Why NVIDIA Agent Toolkit matters for businesses
NVIDIA is assembling an open stack of models, sandbox runtime and skills that enterprise software vendors are already adopting. Agencies that need self-hosted agents for regulated clients get a fuller open alternative to closed agent platforms, though Ultra itself requires data-center hardware.
