Regions & Providers
Spheron sources GPU and CPU capacity from seven providers across North America, Europe, the Middle East, and Asia Pacific. Most GPUs are NVIDIA; Spheron AM supplies AMD Instinct, and Intel Gaudi2 is available through Sesterce and Spheron MS.
GPU inventory changes as providers add and withdraw hardware. The tables below list representative capacity; check the GPU catalog for live availability and pricing.

Instance Lifecycle Support
Stopping an instance keeps its disk while the GPU stops billing. Restarting reboots it in place. Neither is available on every provider, and the two do not line up with each other.
| Provider | Stop and start | Restart |
|---|---|---|
| Spheron AI | Yes, depending on machine type and region | Yes |
| Spheron ES | Yes | No |
| Spheron MS | No | Yes, on virtual machines |
| Spheron AM | No | Yes |
| Massed Compute | No | Yes |
| Verda | No | No |
| Sesterce | No | No |
On a provider that cannot stop an instance, the instance bills at the full hourly rate until you destroy it. Some machine types also carry a provider minimum runtime longer than the 20 minute default, charged in full even if you terminate early; the deploy wizard shows the figure before you commit. See Instance lifecycle for stopped rates, capacity risk on start, and the API endpoints.
Provider Details
Verda
Verda operates in EU regions across three Finland data centers: Finland 1, Finland 2, and Finland 3. It provides both Spot and Dedicated instances with NFS volume support.
CPU Node: Verda is the only provider offering CPU nodes at spot rates, from $0.09/hr. Sizes run 4 vCPU / 16 GB, 8 vCPU / 32 GB, 16 vCPU / 64 GB, and 32 vCPU / 128 GB. See CPU Nodes.
Verda volumes (NVMe_Shared NFS type) support multi-instance attachment: a single volume can be mounted on multiple GPU instances simultaneously. Each instance supports at most one shared volume.
Local storage for Dedicated instances: When deploying a Verda Dedicated instance you choose between two root-disk sizes: 500 GB (default) or 1 TB. Select 1 TB when your workload requires more local dataset or checkpoint space than the default provides.
Sesterce
Sesterce provides Dedicated GPU instances across North America, Europe, India, Japan, Singapore, and Australia (GDPR, SOC 2 Type II, ISO 27001 certified). Inventory spans B300 SXM6 and H200 SXM5 at the high end down to L4 and A10 for inference.
Sesterce volumes attach as raw block devices formatted with ext4. A volume binds at instance creation and cannot be attached or detached afterwards, and each instance takes a single volume. See the Sesterce volume mounting guide.
CPU Node: Sesterce offers Dedicated CPU nodes across the widest region choice of any provider, from 4 vCPU / 4 GB up to 32 vCPU / 128 GB, in Europe (Helsinki, Frankfurt, Oslo, London), North America (Ashburn, Dallas, Des Moines, Houston, Kansas City, Calgary, Montreal), and Tokyo.
Spheron AI
Spheron AI provides on-demand and spot GPU instances across North America and Europe, sourced from Tier 3 data centers. Current inventory includes H100 (NVL/PCIe), A100 80GB (NVL/PCIe/SXM4), L40, and RTX 4090 across Canada 1, Montreal 1, Norway 1, Oslo 1, and the United States. Stock rotates; check the catalog for what is deployable right now.
Startup scripts (cloud-init) are fully supported. Spheron AI volumes are block-device backed and can be created up to 50 TB per volume in the new regions, with up to 10 volumes attached to a single instance. See the Spheron AI volume mounting guide for setup. The size slider in the create-volume wizard adapts to the per-region storage ceiling.
OS images: 11 OS images are available, including Ubuntu 22.04/24.04, AlmaLinux 9, Debian 12, and CUDA-enabled variants (R535, R550, R570). The default is Ubuntu Server 22.04 LTS with CUDA 12.8 and Docker pre-installed.
SSH access: Port 22 opens automatically on every new Spheron AI instance; no firewall configuration is needed for SSH.
CPU Node: Spheron AI offers Dedicated CPU nodes from 4 vCPU / 4 GB up to 32 vCPU / 64 GB in Norway 1 and Canada 1.
Spheron ES
Spheron ES (Extra Supply) provides on-demand and spot GPU instances across five regions: EU North 1 (Finland), EU West 1 (France), UK South 1 (United Kingdom), ME West 1 (Middle East), and US Central 1 (United States). Inventory currently spans B300 SXM6, B200 SXM6, H200 SXM5, H100 SXM5, L40S, and RTX Pro 6000, all flagged with the Tier 3 DC compliance badge.
Spheron ES does not offer CPU nodes. Deploy CPU work on Verda, Sesterce, Spheron AI, or Massed Compute.
Shared volumes use the virtiofs protocol and support multi-instance attach, in-place resize, and up to 256 TiB per volume. See the Spheron ES volume mounting guide for setup.
Spheron MS
Spheron MS (Multi Supply) provides Dedicated GPU instances across a wider geographic footprint than any other provider on the platform: the United States (Austin, Ashburn, Chicago, Culpeper, Dallas, Dulles, Houston, New York, Phoenix, Salt Lake City, San Jose), Canada (Calgary), Norway (Oslo), Poland (Warsaw), Israel (Jerusalem), India (Mumbai), Japan (Tokyo), Singapore, and Australia (Sydney). Inventory runs from H200 SXM5 and H100 SXM5 at the high end down to L4 and A10 for inference, and includes Gaudi2.
Each offer names its region, and the region on the offer is the region you deploy into. A machine that is out of stock shows as sold out rather than disappearing, so you can set a stock notification instead of wondering where a GPU went.
Instance types: Dedicated only. Spheron MS does not offer spot pricing. Where an offer is a full physical server it is listed as bare metal and labelled on the card. See Instance types.
Volumes: A Spheron MS volume is selected during deployment and only then. There is no attach or detach for an instance that is already running, each instance takes one volume, and the volume must be in the same region as the instance. Size and name are fixed at creation. See the Spheron MS volume mounting guide.
Boot disk: Each machine type ships a fixed boot disk, so its size appears on the offer rather than being something you set. Pick a machine type with the disk you need, or attach a volume for the rest.
Lifecycle: Spheron MS cannot stop an instance, so an instance bills at the full hourly rate until you destroy it. Restart is available on virtual machines and reboots in place without changing billing. Bare metal instances support neither.
OS images: Ubuntu 20.04, 22.04, and 24.04, with CUDA 12.0, 12.2, 12.4, 12.8, and 13.0 variants. Startup scripts (cloud-init) are supported on every offer.
CPU Node: Spheron MS does not offer CPU nodes. Deploy CPU work on Verda, Sesterce, Spheron AI, or Massed Compute.
Spheron AM
Spheron AM supplies AMD Instinct MI300X, the first non-NVIDIA silicon on the platform. Each GPU carries 192 GB of HBM3e, and the catalog publishes 1x, 2x, and 4x GPU configurations from a single region, Michigan 1 in the United States.
The 192 GB per GPU is the reason to choose it: a model that needs several 80 GB NVIDIA cards to hold its weights can fit on fewer MI300X GPUs, which changes how you shard it.
Compute stack: These machines run ROCm, not CUDA. Most PyTorch and TensorFlow code runs unchanged, but nvidia-smi does not exist and CUDA-only wheels and Docker images do not work. See ROCm and AMD Instinct before you deploy.
Instance types: Dedicated only. Spheron AM has no spot option.
OS images: One image, Ubuntu with ROCm plus Docker or Podman. There is no image picker, because the machine type determines what it boots. Startup scripts (cloud-init) are supported.
Boot disk: Fixed by the machine type, so its size appears on the offer rather than being something you set.
Volumes: Not available. A deployment that asks for a volume is refused rather than created without it. Keep anything that must survive termination off the instance.
Lifecycle: Restart reboots in place. Stopping is not available, so an instance bills at the full hourly rate until it is destroyed. Terminate an instance you have finished with.
Minimum runtime: Each machine type carries its own minimum reservation, which can exceed the 20 minute default and is charged in full even if you terminate early. The deploy wizard shows the figure before you commit.
CPU Node: Spheron AM does not offer CPU nodes.
Massed Compute
Massed Compute provides Dedicated GPU instances in US regions (us-central-1 through us-central-9 and us-east-1) with H100 PCIe, A100 80GB PCIe, L40S, L40, RTX 6000 Ada, RTX Pro 6000, A6000, and A30 configurations. Massed Compute does not support volume mounting.
CPU Node: Massed Compute offers Dedicated CPU nodes at 8 vCPU / 32 GB, 14 vCPU / 40 GB, 28 vCPU / 80 GB, and 52 vCPU / 160 GB, from $0.12/hr, in us-central-2, us-central-3, and us-east-5. See CPU Nodes.
Compliance certifications: HIPAA, SOC 2 Type II.
