LLM Inference Optimization Overview

Why it matters

Inference optim shapes serving cost. Understanding shapes design.

The architecture

Quantize weights.

PagedAttention + KV compression.

Continuous batching.

Speculative decoding.

Optimized kernels.

How it works end to end

vLLM + TRT-LLM + SGLang combine techniques.

Speculative decoding + FP8 latest.

Chunked prefill for TTFT.
