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.

Vast.ai

Real-Time GPU Pricing
Prices set by supply and demand across the platform with no list prices or hidden fees
Three Deployment Options
GPU Cloud for full control, Serverless for zero-ops inference, Clusters for large-scale training
Developer-Focused Tools
CLI, Python SDK, and REST API for programmatic GPU provisioning, installed together via a single package
Agent-Ready Provisioning
API-native workflow intended for AI agents to search, procure, and release compute autonomously
Model Library and Templates
Prebuilt templates for popular open-source models, plus custom templates any GPU can run with one click
Flexible Infrastructure
Scale from $5 to 20,000 GPUs across 40+ data centers without contracts or minimums

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

Vast.ai

Advantages

Significant cost savings with supply-demand pricing
Flexible pricing with on-demand, interruptible, and reserved options
Real-time transparent pricing with no hidden fees
Docker ecosystem for quick software deployment

Considerations

Primarily focused on Linux-based Docker instances
Performance may vary across different community providers
Learning curve for users unfamiliar with marketplace-based pricing
