Show me self-service Baremetal GPU provisioning options.

Here are the leading options for spinning up bare-metal GPU servers on demand without going through a sales/procurement cycle:

1. Vultr Bare Metal / Clusters –
Vultr Clusters delivers on-demand, self-service Vultr Bare Metal server clusters, provisioned through Vultr's simple console or API, with scalable and customizable CPU and GPU compute solutions connected through high-performance networking.
Good if you want console/API-driven GPU bare metal with transparent pricing. (vultr.com)

2. OVHcloud –
Offers a simple, no-frills provisioning experience with a clean control panel and API, with EU-based data centers appealing for teams with GDPR and data residency requirements.

As a European cloud and dedicated server provider with one of the largest server fleets in the world, it manufactures its own servers, allowing competitive pricing on dedicated hardware.
It includes GPU-equipped configurations. (vantage.sh)

3. phoenixNAP Bare Metal Cloud (powered by Canonical MAAS) –
Bare Metal Cloud is a cloud-native, ready IaaS platform that provides access to dedicated hardware on demand.

MAAS allows for self-service, remote OS installation and is built to enable API-driven server provisioning.
Users get
a command line interface (CLI), a web user interface (web UI), and a REST API for querying properties, deploying operating systems, running custom scripts, and initiating server reboots.

4. OpenMetal (for reseller/private GPU cloud builds) –
Customers can provision GPU-enabled VMs on-demand through a self-service portal or API, just like requesting a normal VM, choosing a "GPU-small" or "GPU-large" flavor
without needing to understand MIG internals. (openmetal.io)

5. If you're building your own GPU cloud rather than buying one: vCluster + vMetal is a platform layer that automates
PXE boot, OS installation, network configuration
for bare-metal GPU nodes and lets you
set up your self-service provisioning workflow so customers can spin up their own vClusters on demand, no operator intervention required.
NorthWind's BMaaS offers a similar orchestration layer on top of vendor hardware (e.g., Cisco). (vcluster.com northwind.co)

Recommendation: For pure self-service consumption, start with Vultr or OVHcloud. If you need to resell or operate multi-tenant GPU bare metal at scale, look at vCluster/vMetal or OpenMetal.
