Hidden Costs to Watch For
- Egress fees: AWS $0.09/GB, GCP $0.12/GB. Dedicated GPU clouds charge zero egress.
- Storage: Hyperscalers $0.10-$0.20/GB/month. Dedicated providers include 20-100GB free.
- Setup/idle time: Charges start at provisioning, not when your job starts.
- Support tiers: AWS Business Support starts at $100/month. Dedicated clouds include support free.
Tips to Save Money
- Use spot instances - save 40-70% on RunPod Community and Vast.ai.
- Reserve capacity for 24/7 workloads - save 20-40%.
- Optimize models first - quantize to 4-bit, use Flash Attention.
- Match GPU to workload - RTX 4090 at $0.40/hr beats A100 for 7B model inference.
- Compare prices regularly - use GPUCloudList to monitor all providers.
