The efficient frontier of LLM inference

Inference engineering applies the concept of an efficient frontier to balance model-serving outcomes such as latency, throughput, cost, and quality, distinguishing between techniques that shift deployments along existing tradeoffs and those that improve overall performance. Batch sizing and GPU parallelism strategies, including tensor, expert, and attention data parallelism, allow operators to prioritize either faster individual responses or greater total throughput, while quantization generally improves serving efficiency but may introduce quality tradeoffs. Frontier-expanding approaches include kernel and runtime optimization, which reduce resources required per token; speculative decoding, which accelerates generation by predicting and validating likely tokens; and prefill/decode disaggregation, which assigns inference phases to specialized workers and can improve throughput while maintaining or modestly improving latency. The effectiveness of these methods depends on workload characteristics, and their benefits can compound when hardware and software improvements are combined.
