LLM Inference Engineering Techniques Reshape AI Performance Tradeoffs and Push Efficiency Boundaries

LLM inference engineering is reshaping AI performance by splitting techniques into two categories: tradeoff managers like batch sizing and quantization that balance latency against throughput, and frontier-pushers like speculative decoding and kernel optimization that deliver compounding, systemwide efficiency gains applicable to both speed and scale simultaneously.

• LLM inference engineering operates on an efficient frontier where techniques either manage tradeoffs between latency and throughput or push the entire frontier outward to create universal efficiency gains.
• Tradeoff management techniques such as batch sizing, parallelism strategy, and quantization allow engineers to target specific performance points, sacrificing per-user speed for higher throughput or vice versa depending on deployment needs.
• Frontier-pushing techniques including kernel optimization, speculative decoding, and prefill/decode disaggregation compound with one another to deliver systemwide performance improvements that can be allocated toward lower latency, higher throughput, or both.
