Cost optimization tips

  • Use spot instances with checkpointing to save 56% on this run
  • Mixed-precision (BF16/FP8) can reduce training time 30–50% on H100 80GB
  • Gradient checkpointing trades ~30% speed for lower VRAM, enabling larger batch sizes

How these estimates work

Training cost

GPU-hours × rate × utilization factor. GPU-hours = GPU count × wall-clock hours. Utilization accounts for idle time during data loading, checkpointing, and communication overhead.

Inference cost

GPU-hours are fixed (GPUs run 24/7 for serving). Cost per request = daily GPU cost ÷ daily requests. Concurrency = requests/sec × latency in seconds.

Break-even

Reserved pricing is billed for all hours in the commitment period regardless of usage. Break-even is the daily utilization at which reserved total cost equals on-demand total cost.
