Quantization and parallelism push out the LLM inference efficient frontier
↗
The article explains how inference engineers use batch sizing, parallelism, and quantization to either target a point on or push out the efficient frontier of LLM serving tradeoffs.
Understanding the efficient frontier helps engineers make deliberate tradeoffs between latency, throughput, and quality when serving LLMs. Techniques like quantization and parallelism can shift the frontier, offering universal gains that can be allocated to whichever outcome matters most.

Batch sizing trades per-user latency against overall throughput and cost per token.
Parallelism strategies like TP, EP, and ADP let engineers favor either latency or throughput.
Quantization pushes out the serving frontier but introduces a jagged quality-efficiency tradeoff.
