Low-precision serving in practice: FP8, FP4, scaling factors and what to validate
How FP8 and FP4 serving works end to end: number formats, scaling granularity, weight versus activation versus KV quantisation, hardware support, calibration, the speed you actually get, and a validation routine before you ship.
