What you'll learn

Trace where the latency comes from

Follow a request from arrival to first token to last token, and see where the time gets lost: queueing, batching, and prefill versus decode.

Pick the right lever for the bottleneck

Match the fix to the problem: KV cache management, chunked prefill, quantization, or speculative decoding, and the compute-bound versus memory-bound tradeoff each one addresses.

Make it feel faster without changing the model

Use streaming and time-to-first-token to improve perceived speed, and batching and concurrency to improve throughput and cost.

Why this topic matters

A capable model can still feel sluggish in production. The lag usually lives in the inference path: how requests queue and batch, prefill versus decode, the KV cache, and whether you stream tokens. Abi does this for a living. She'll show you where the latency comes from, and patterns that make agentic systems feel faster while costing less. There's a hands-on exercise so you can see it yourself.
