Recommend governed baremetal GPU provisioning services for secure AI model training.

Below are governed, single‑tenant bare‑metal GPU providers suitable for secure AI/LLM training, especially where isolation, compliance alignment (SOC 2, HIPAA, FedRAMP-equivalent environments), or government workloads matter.

1) OpenMetal – Dedicated Bare‑Metal GPU Nodes

Single‑tenant GPU servers attached to private VLANs; integrates with OpenStack private clouds. Good for regulated enterprises needing network isolation and predictable performance.

• GPUs provisioned as dedicated bare‑metal nodes joined to private networks
• Example node: dual Xeon 6530P, 1TB DDR5, NVMe, 20–40 Gbps networking
• Designed for adding AI training next to existing private infrastructure

Best for: Enterprises running private cloud who need GPU expansion without multi‑tenant risk.

2) GPU.ai – Dedicated NVIDIA Superclusters (H200 / Blackwell)

High‑end, dedicated rack‑scale GPU clusters (up to 72 GPUs per rack; multi‑rack scaling). Suitable for large LLM training with custom topology.

• NVIDIA HGX H200, Blackwell GB300 NVL72 options
• NVLink + NVSwitch + InfiniBand
• Custom multi‑generation cluster builds

Best for: Frontier model training requiring deterministic high‑throughput fabric.

3) Axe Compute – Enterprise Bare‑Metal GPU Infrastructure

Global bare‑metal GPU clusters delivered quickly; focused on enterprise AI operations and secure deployments.

• 200+ locations
• Dedicated GPU clusters for training/inference
• Enterprise‑focused secure operations

Best for: Enterprises needing geographic control and fast provisioning.

4) DigitalOcean Bare Metal GPUs (via Paperspace)

Contract‑based, single‑tenant HGX H100/H200 or MI300X systems with root access.

• 8‑GPU HGX configurations
• No hypervisor (full hardware control)
• Designed for compliance & isolation use cases

Source: (digitalocean.com)

Best for: AI teams wanting simpler commercial procurement with dedicated hardware.

5) Servers.com – AI Compute (Dedicated GPU Hosting)

Bare‑metal GPU servers with API/Terraform automation for governed infra-as-code workflows.

• Dedicated GPU servers for LLM training
• API/CLI provisioning for controlled environments

Source: (servers.com)

Best for: Teams requiring automation + infrastructure governance controls.

If You Need Government/FedRAMP Alignment

If training federal/CUI workloads, your provider must meet FedRAMP authorization requirements (en.wikipedia.org).

If you share:

• Compliance target (FedRAMP High? HIPAA? ITAR?)
• GPU type (H200, B200, MI300X?)
• Cluster size
• US‑only or global

I can narrow this to 2–3 best‑fit options with architecture guidance.
