Introducing NVIDIA HGX B300 on the Essential Cloud for AI

This post announces the general availability of NVIDIA HGX B300 on CoreWeave Cloud, specifically engineered for agentic AI workloads. It details how the HGX B300's enhanced interconnect speed (NVIDIA Quantum-X800 InfiniBand), BlueField-3 DPUs, and 800 Gbps ConnectX-8 SuperNICs improve NVFP4 inference performance and increase GPU memory capacity. Benchmarks demonstrate 3.42x faster token generation on Kimi K2.5 and 4.93x faster end-to-end request latency on DeepSeek-R1 compared to NVIDIA HGX H200. The post highlights the integration of HGX B300 with CoreWeave's existing AI infrastructure, including Mission Control for fleet management, CKS and SUNK for orchestration, and AI Object Storage for data access, emphasizing the platform's ability to accelerate agentic AI development through reduced friction, operational visibility, and high-throughput execution.
