NVIDIA launches BlueField-4 to power the operating system of AI factories

NVIDIA announced the BlueField-4 data processing unit at GTC Washington, D.C., positioning it as the core operating system for next-generation Artificial Intelligence factories. BlueField-4 is part of the broader BlueField platform and is designed to accelerate gigascale Artificial Intelligence infrastructure, delivering high-performance inference, software-defined acceleration across storage, networking and security, and support for 800Gb/s throughput to meet rising demand for trillion-token workloads.

Technically, BlueField-4 pairs an NVIDIA Grace CPU with NVIDIA ConnectX-9 networking to provide what NVIDIA describes as six times the compute power and support for Artificial Intelligence factories up to four times larger than those possible with BlueField-3. The platform includes native support for NVIDIA DOCA microservices, enabling containerized services that secure, scale and simplify deployment and operations. BlueField-4 also supports a multiservice architecture with service function chaining, multi-tenant networking, rapid data access and cloud elasticity. ConnectX-9 SuperNICs are highlighted for ultralow-latency networking, optimized RoCE performance and predictable networking for demanding workloads when used with NVIDIA Spectrum-X Ethernet.

Security is anchored by the NVIDIA BlueField Advanced Secure Trusted Resource Architecture, which enables secure bare-metal compute instances with zero-trust tenant isolation and full software-defined infrastructure control. NVIDIA positions BlueField-4 as delivering consistent performance and security across its infrastructure portfolio, including NVIDIA RTX PRO Servers, HGX, DGX, GB200 and GB300 systems, as well as data-center designs like the Enterprise Artificial Intelligence Factory validated design, AI Data Platform, DGX SuperPOD and cloud partner reference architectures. A broad ecosystem of server and storage vendors, cybersecurity companies, cloud and Artificial Intelligence providers, platform software vendors and global systems integrators are planning BlueField-4 adoption. NVIDIA expects BlueField-4 to be available in early availability as part of Vera Rubin platforms in 2026.
