RunPod vs Vast.ai GPU Cloud

Compare →Size memory before shopping by hourly price.
Model weights, precision, context, KV cache, framework overhead and batching determine whether a workload fits. A cheaper GPU that cannot complete the run is not a saving.
Compare the dated rate, then calculate successful completed-job cost.
The official-source index records VRAM, billing unit, region evidence, storage and transfer boundaries. Then add setup, retries and idle time so one hourly number does not become a false total-cost comparison.

Checkpoint before trusting a long run.
Keep important artifacts outside the disposable compute instance, test restoration and document every billable resource that must be stopped.
Price hosted model APIs before renting infrastructure.
Use the same monthly request and token assumptions across official model rates, then compare a separate GPU deployment scenario only when the workload can use an open-weight model.
