CoreWeave (CRWV) Expands AI Cloud Platform With NVIDIA HGX B300 Instances for Blackwell Ultra

CoreWeave Inc. (NASDAQ:CRWV) is one of the most promising stocks under $100 to buy. On March 16, CoreWeave announced a significant expansion of its AI-native cloud platform at the NVIDIA GTC conference, introducing the general availability of NVIDIA HGX B300 instances. This new generation of hardware, part of the Blackwell Ultra platform, features a 50% increase in memory and doubled node-to-node bandwidth to support long-context inference and models with over 100 billion parameters.

To maintain sustained peak performance for these mission-critical workloads, every server is managed by state-of-the-art liquid cooling technology to prevent thermal throttling. The platform expansion is specifically designed to support the industry shift from large-scale model training to the deployment of autonomous agents and physical AI.

Through a partnership with Weights & Biases, CoreWeave is introducing environment-free reinforcement learning and advanced production evaluations. These tools allow agents to learn through continual on-the-job training rather than costly simulated environments, while automated scoring and failure detection help researchers refine models based on real-world user interactions. Looking ahead, CoreWeave Inc. (NASDAQ:CRWV) expects to be among the first cloud providers to deploy the NVIDIA Vera Rubin NVL72 platform in H2 2026.
