## Summary

OpenRouter says a self-hosted model on a rented RTX 3090 breaks even with the API at about 12% load for Qwen3.8 27B, but a DeepSeek V4.1 Flash setup on four rented H200s never beats the cheapest zero-data-retention endpoint. The break-even divides GPU rent per hour by the API cost of the tokens that GPU serves in the same hour. OpenRouter adds that provider.zdr and its EU and US domains cover most privacy needs without self-hosting.
