GPU vs API break-even
See whether renting an A100-class box beats list API prices.
GPU / vLLM TCO estimates when self-hosted GPU hours beat API list prices for a given throughput. You enter GPU $/hour, utilization, and sustained tokens per second, then compare break-even against catalog API models. It is chip rental versus token spend — not full datacenter TCO.
Add networking, ops, and egress in your own spreadsheet. Utilization below about 40% stretches break-even hard because you still pay for idle capacity.
Estimate when self-hosted GPU hours beat API list prices for a given throughput. Use it before committing to A100/H100 capacity for vLLM.
Enter GPU hourly cost and utilization, set sustained tokens per second, pick API models to compare, then read months-to-break-even and monthly delta. Use it before you commit capacity, not after the cluster is already idle.
Enter GPU hourly cost and utilization.
Set tokens/sec sustained throughput.
Pick API models to compare break-even against.
Read months-to-break-even and monthly delta.
No. This page is GPU dollars per hour versus API token spend at a throughput you enter. Networking, engineers, storage, and egress are extra. Treat the output as a first filter, not a purchase order.
When utilization is low, traffic is spiky, or you need many model SKUs. APIs win on burst and variety. Self-hosting wins on steady, high tokens/sec on one or two models you already trust.
GPU / vLLM TCO estimates when self-hosted GPU hours beat API list prices for a given throughput. You enter GPU $/hour, utilization, and sustained tokens per second, then compare break-even against catalog API models. It is chip rental versus token spend — not full datacenter TCO.
This tool focuses on GPU $/hr vs API token spend. Add networking, ops, and egress in your own spreadsheet for full TCO.
Break-even self-hosted GPU hours against API model pricing.
Calculators run on the numbers you enter in this tab. They do not upload a spreadsheet to OmniKit servers.

GPU / vLLM TCO lives at omnikitapp.net/tools/gpu-vllm-tco. Estimate when self-hosted GPU hours beat API list prices for a given throughput. Use it before committing to A100/H100 capacity for vLLM. Use it as an operator page, then confirm invoices, policies, or published facts on the source. OmniKit does not sell detector evasion or ranking guarantees.
