- Quality parity is not guaranteed when swapping to open weights.
- Model the break-even QPS before buying hardware.

FAQ
How do I find break-even QPS?
Divide monthly GPU cost by per-request API cost from the calculator.
Should I include DeepSeek as a third option?
Yes — managed DeepSeek often sits between GPT-4o and self-host TCO.
Is OmniKit a hosting cost tool?
It estimates tokenized API-style spend; GPU quotes still need your infra spreadsheet.
