Architectural Economic Verdict: At your current monthly scale of 100M input and 25M output tokens, the managed Cloud API is vastly superior financially ($525/mo vs $16,128/mo self-hosted). Dedicated 8x H100 cluster hosting only becomes economically viable if your continuous monthly volume exceeds 3.1 Billion tokens or if strict on-prem sovereign data compliance is legally required.
