Equation 21 · Part 1 · The Real Economics of Shipping a Model to a Device
Symbol C_dev
What this part means
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.
Its job in the formula
ev is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it
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.
The passage around this formula
The equation also explains something the variant-matrix section set up: rises with every additional tier, chip target and quantization scheme a release has to validate, which means rises too. A feature built once and validated across three device tiers has a lower bar to clear than the same feature validated across six, holding…
