The question to ask first
Self-hosting is not cheaper because a GPU hourly price looks low. It becomes cheaper only when the workload keeps the GPU busy enough to beat managed API margins after storage, egress, monitoring, idle time, and operations are included.
Break-even inputs
The Price Gouge model uses verified GPU hourly prices, storage prices, egress prices, and provider token prices. The most sensitive inputs are utilization, cache hit rate, output ratio, and retry rate.
- Frontier API break-even arrives earlier than open-model API break-even.
- Idle time turns reserved GPUs into fixed monthly waste.
- Marketplace GPU pricing needs reliability and interruption scoring.
Practical threshold
Price self-hosting only after a measured benchmark proves throughput, quality, concurrency, and latency on your real prompts. For many teams, hosted open-model APIs remain cheaper until utilization is steady and high.
