How to trade model quality vs latency in production?

medium

Answer

  • (1) Distill large model into smaller.
  • (2) Ensemble → single model.
  • (3) Quantize (fp32 → int8) — usually <1% quality loss.
  • (4) Prune (remove low-magnitude weights).
  • (5) Two-stage: cheap first, expensive rerank on top-K.
  • (6) Adaptive compute: run cheap model, escalate uncertain cases to expensive.
  • (7) Cache results for repeated queries.
  • (8) Speculative decoding for autoregressive.
  • Measure Pareto frontier: for each latency budget, what's best quality?
  • Choose based on business SLA.
Check yourself — multiple choice
  • Random
  • Distill + quantize + prune + two-stage + adaptive compute + cache + speculative decoding; measure Pareto frontier (quality vs latency); pick per business SLA
  • Just faster
  • Not real

Quality/latency: distill + quant + prune + two-stage + Pareto frontier.
