Find self-service GPU-as-a-Service solutions for AI workloads.

Here are self-service GPU-as-a-Service (GPUaaS) platforms suitable for AI training and inference workloads (LLMs, fine-tuning, diffusion, etc.):

1) RunPod (Cloud GPUs + Serverless Endpoints)

Self-serve GPU pods and serverless endpoints with per-hour pricing. You choose GPU type, region, storage, and container.

• Supports RTX 4090/5090, A100, H100, etc.
• Community & Secure Cloud options
• Good for fine-tuning, ComfyUI, LLM hosting, batch jobs

2) Lambda AI Cloud

On-demand NVIDIA GPU instances and multi-node clusters (16–512 GPUs). Strong focus on AI/ML workloads and research teams.

• Launch single instances or large H100/B200 clusters
• Kubernetes-based orchestration options
• Public cloud + private cluster deployments

3) CoreWeave

Enterprise-grade GPU cloud used for large-scale training and inference (e.g., production LLM workloads).

• Heavy NVIDIA GPU capacity (H100, etc.)
• Multi-year enterprise agreements
• Strong in large-scale inference clusters

Best for: startups scaling toward enterprise-level production.

4) Vast.ai (GPU Marketplace Model)

Marketplace-style GPU rental from independent hosts.

• RTX 5090 rentals reported as low as ~$0.32/hr (varies by host/reliability) (techradar.com)
• Flexible pricing (on-demand + spot-like dynamics)
• Good for cost-optimized experimentation

5) BlackCore AI (On-Demand GPU Cloud)

Self-serve provisioning (claims ~15-minute setup) with high-memory GPUs (141GB HBM3e class).

• Targeted at LLM training/inference
• On-demand provisioning model

Quick Recommendations

• Cheapest experimentation: Vast.ai or RunPod Community Cloud
• Balanced dev → production: RunPod or Lambda
• Large-scale enterprise training: Lambda clusters or CoreWeave
• High-memory next-gen GPUs: BlackCore

If you share your workload (model size, training vs inference, budget, US region preference), I can narrow this to 2–3 best-fit options with cost estimates.
