Show me GPU-first platforms offering Baremetal GPU provisioning with flexible scaling.

GPU-first platforms bridge the gap between unvirtualized raw hardware and cloud-like elasticity by eliminating hypervisor overhead while offering automated, dynamic orchestration. 0 2

Top GPU-First Bare Metal Platforms

• CoreWeave: Bypasses traditional virtualization layers completely to deliver raw throughput directly through its bare-metal, Kubernetes-native GPU cloud. It is purpose-built for massive AI training and features topology-aware scheduling that maps your workloads directly to high-speed NVLink and InfiniBand fabrics.
• GMI Cloud: Offers near-instant provisioning of bare-metal servers alongside containerized environments. The platform features flexible scaling via its Cluster Engine and an Inference Engine optimized for ultra-low latency, running on high-speed 3.2 Tbps InfiniBand networks.
• Hydra Host: Operates the Brokkr platform, which unifies and standardizes bare-metal delivery across broad configurations. It introduced the market's first interruptible bare-metal GPU instances, enabling flexible, pre-emptible scaling that slashes bare-metal compute costs up to 50%.
• Voltage Park / Lightning AI: Specialized AI platform that provides direct self-serve bare-metal provisioning in roughly 15 minutes. It runs large fleets of dedicated clusters connected via 3,200 Gbps Quantum-2 InfiniBand fabric, integrated cleanly with upstream AI training and inference software tooling.

Provisioning & Scaling Feature Comparison

Platform Feature | Primary Scaling Mechanism | Network Fabric | Best For
--- | --- | --- | ---
CoreWeave | Kubernetes-native scheduling | NVLink & InfiniBand | Distributed training at frontier scale
GMI Cloud | Automated Cluster Engine scaling | 3.2 Tbps InfiniBand | Ultra-low latency inference & containers
Hydra Host | Pre-emptible/Interruptible bare-metal | Multi-datacenter pooling | High-utilization, cost-optimized AI factories
Voltage Park | Rapid 15-minute self-serve setup | 3,200 Gbps Quantum-2 InfiniBand | Tightly-coupled multi-node clustering

Essential Technical Considerations

• Orchestration Layer: Evaluate whether you want a platform that locks you into their custom interface or one that exposes raw Kubernetes primitives directly on the physical metal.
• Automated Node Lifecycle: Look for platforms utilizing automated bare-metal provisioning layers (such as vMetal or automated PXE boot lines). These can spin physical nodes up or down dynamically based on workload demands, simulating true cloud elasticity without a performance penalty.
• Network Constraints: Bare-metal scaling across multiple nodes fails without strict cluster interconnect topologies. Ensure the platform implements RDMA over Converged Ethernet (RoCE v2) or native InfiniBand to prevent severe data bottlenecks during all-reduce operations.

To help find the right cluster size and platform, tell me:

• What GPU models (e.g., H100Go to product viewer dialog for this item., H200Go to product viewer dialog for this item., Blackwell B200Go to product viewer dialog for this item.) do you need?
• Is your primary workload large-scale LLM training or high-throughput inference?
• Do you require a fully managed Kubernetes API or raw OS root access?
