Market context: Median H100 on-demand price across providers is $2.99/hr. Reserved instances offer 30-40% discounts. Industry projections suggest H100 may fall below $2/hr universally by mid-2026.²³

Lambda's zero egress fees and RunPod's free data transfer provide value not reflected in hourly rates for data-intensive workloads.

Commitment requirements

Lambda offers committed pricing reducing H100 costs substantially for organizations with predictable demand. The commitment structure suits production workloads with steady utilization. Spot and on-demand pricing accommodate variable workloads.

Paperspace's multi-year commitments lock organizations into pricing that may become uncompetitive as the market evolves. Organizations should carefully evaluate whether commitment duration matches their planning horizon. Shorter commitments or on-demand pricing preserve flexibility.

Vast.ai operates on purely on-demand pricing without commitment requirements. The flexibility suits experimentation and variable workloads. Organizations with steady demand may find better economics through committed pricing elsewhere.

Hidden costs

Data transfer fees significantly impact total cost for workloads moving substantial data. Lambda's zero egress policy eliminates this variable. Other providers charge $0.08-0.12 per GB for egress, which compounds quickly for large model weights or training datasets.

Subscription fees add to effective hourly rates for providers requiring paid tiers. Paperspace's Growth plan at $39 per month affects economics for light users. Heavy users amortize subscription costs across many GPU-hours.

Spot and preemptible instance interruption creates hidden costs through lost work. Checkpointing overhead, restart time, and occasional complete restarts affect effective throughput. Reliable instances may cost more per hour but less per completed workload.

Capability comparison

Beyond pricing, providers differ in available hardware, software ecosystem, and operational capabilities.

GPU availability

Lambda focuses on data center GPUs including A100 and H100 variants. The focus ensures consistent, production-grade hardware across instances. Consumer GPUs are not available, limiting options for cost-sensitive experimentation.

Paperspace offers both data center and consumer GPUs, from RTX 4090 through A100 and H100. The range enables matching hardware to workload requirements and budgets. Consumer GPUs suit inference and small training runs while data center GPUs handle larger workloads.

Vast.ai's marketplace includes the widest hardware variety, from consumer RTX cards through data center GPUs. The variety enables finding precisely matched hardware. Quality and performance vary by host, requiring evaluation of individual offerings.

Software and tooling

Lambda provides pre-configured ML environments with popular frameworks and tools. The environments reduce setup time and ensure consistent configurations. Custom environments are also supported for specialized requirements.

Paperspace's Gradient platform provides managed ML infrastructure with notebook serving, experiment tracking, and deployment pipelines. The platform approach suits teams wanting managed MLOps without building infrastructure. Standalone VMs are available for teams preferring custom setups.

Vast.ai provides basic VM access with user-supplied software stacks. The minimal platform requires more self-sufficiency but provides maximum flexibility. Template images and user documentation partially address the setup burden.

Multi-GPU and clustering

Lambda supports multi-GPU instances and cross-instance clusters for distributed training. High-bandwidth interconnects between GPUs enable efficient scaling. The capability suits large model training requiring multiple accelerators.

Paperspace offers multi-GPU instances but limited cluster capabilities. Single-node multi-GPU training works well. Distributed training across instances requires more manual configuration.

Vast.ai's distributed hosts lack coordinated networking for efficient multi-host training. Single-host multi-GPU configurations work when available. Organizations requiring clusters should look elsewhere.

Use case alignment

Different providers align with different use cases based on their characteristics.

Development and experimentation

Vast.ai's low prices make it ideal for experimentation where GPU cost sensitivity outweighs reliability requirements. Developers can try ideas cheaply before investing in production infrastructure. The marketplace model provides access to diverse hardware for compatibility testing.

Paperspace's user-friendly platform suits developers new to GPU computing. The low friction onboarding enables rapid prototyping. Managed notebooks reduce infrastructure overhead for small teams.

Production inference

Lambda's combination of competitive pricing, reliability, and zero egress fees suits production inference serving. Consistent hardware and software stacks simplify deployment. SLA-backed availability protects production workloads.

Hyperscalers remain dominant for production inference requiring integration with broader cloud services. Organizations with existing cloud infrastructure may prefer consistent providers despite premium pricing.

Large-scale training

Lambda and hyperscalers provide the multi-GPU and cluster capabilities large-scale training requires. High-bandwidth interconnects and coordinated scheduling enable efficient distributed training. Alternative providers generally lack these capabilities at scale.

Reserved capacity through commitment pricing makes economic sense for sustained training workloads. Organizations training large models regularly should negotiate committed pricing with capable providers.

Operational considerations

Provider selection involves operational factors beyond pricing and capabilities.

Support and SLAs

Lambda provides enterprise support options with defined response times and escalation paths. Support quality affects operational experience, especially during incidents. Enterprise agreements should include support terms.

Paperspace benefits from DigitalOcean's support infrastructure. The acquisition brought improved reliability and support compared to standalone startup operations. Enterprise customers access priority support.

Vast.ai's marketplace model provides limited platform support. Issues with individual hosts require host-level resolution. The model suits self-sufficient operators comfortable troubleshooting independently.

Security and compliance

Lambda operates its own infrastructure with defined security practices. Organizations with compliance requirements should evaluate Lambda's security posture against their needs. SOC 2 and similar certifications may be available.

Paperspace and DigitalOcean provide documented security practices and compliance certifications. The cloud provider model enables standardized security controls. Enterprise agreements address specific compliance requirements.

Vast.ai's distributed model complicates security assessment. Individual hosts have varying security practices. Organizations with strict security requirements should carefully evaluate marketplace suitability.

Hybrid strategies

Organizations can combine providers to optimize for different use cases. Vast.ai for experimentation, Lambda or RunPod for production inference, and CoreWeave for large-scale training creates a portfolio approach. The complexity requires management but optimizes economics and hedges against capacity constraints.
