Features Comparison

Impossible Cloud

Bare Metal GPU Clusters
Dedicated NVIDIA systems without virtualization, from 2-GPU PCIe servers to 8-GPU SXM nodes and GB300 NVL72 racks, with InfiniBand or RoCE interconnect on larger clusters.
Published Term Pricing
Each listed cluster shows a per-GPU-hour rate for every available contract term, from one month to 60 months, along with region, node count and availability date.
Public Pricing Feed
The GPU offer list is published as an unauthenticated JSON feed, regenerated daily.
S3-Compatible Object Storage
Object storage compatible with the AWS S3 API, with no egress or API-call fees and no minimum storage duration.
Managed Inference
OpenAI-compatible inference endpoints for open-weight models (DeepSeek, Qwen, Kimi, GLM, gpt-oss, Nemotron), billed per million tokens; currently in early access.
Compliance
Headquartered in Germany with ISO 27001 certification and GDPR-aligned data handling in European data centers.

Spheron

Multi-provider marketplace
Access GPU capacity from multiple cloud providers and certified data centers from one account, without separate signups per provider
Per-minute billing
Instances are billed by the minute rather than rounded up to the hour, past a 20-minute minimum runtime (60 minutes for a 2x AMD MI300X)
Fast provisioning
NVIDIA instances are typically ready in under two minutes with no approval workflow or provisioning queue
Unified billing and cost tracking
Compute spend across every connected provider is tracked in a single dashboard
Full root access instances
Each VM or bare metal instance includes NVMe SSD storage, network bandwidth and full root access, with a dedicated IP on NVIDIA instances
Supplier matchmaking
Spheron sources large clusters, specific hardware and InfiniBand configurations from its partner data center network, with a typical quote turnaround of 24-48 hours

Pros & Cons

Impossible Cloud

Advantages

Per-GPU-hour rates published for every listed cluster and contract term
GPU compute and S3 object storage from one provider, so data and compute can sit in the same region
Dedicated bare metal hardware without virtualization
German headquarters and European data residency options

Considerations

No on-demand hourly rate; all GPU capacity is sold on committed terms
Many listed clusters have a future availability date rather than immediate capacity
Some listings show region, configuration or node count only on request

Spheron

Advantages

One account and dashboard spans several GPU clouds, avoiding per-provider lock-in
Per-minute billing past a short minimum runtime, with no contract or long-term commitment
Wide NVIDIA range from RTX 4090 through B300 plus the AMD MI300X, with GB200, GB300 and R100 available to reserve
Spot instances run the same hardware at up to 50% off dedicated rates

Considerations

Capacity is supplied by third-party data centers, so hardware, regions and operational experience vary by partner
Spot instances are interruptible and can be reclaimed when demand returns
Large clusters, custom configurations and reserved capacity go through sales rather than self-service
