The passage around this formula
Define as the fixed, per-release engineering and QA cost of producing and validating the device-tier variant matrix described above — the harness time, the pass/fail sign-off per tier, per quantization scheme, per chip target. Define U as the cost of distributing model updates to the installed fleet, expanded in the next section. Define as the marginal cost of one additional on-device inference and as the marginal cost of one additional cloud-served inference of the same model. Total cost over Q queries under each placement is
