Track for LLM serving: tokens/sec, p95 TTFT, p95 TPOT, queue time, OOM rate, cost/1M tokens. Report fractions like 36/40, not vague quality adjectives. Segment by language, plan tier, document length, or other slices that matter for the multi-tenant chat API.

Protocol
Freeze inputs and neighboring versions while evaluating LLM serving. Change one control. Pair results case by case on the multi-tenant chat API. Define hard gates (severe errors, privacy, latency) before the bake-off. Use deterministic checks where possible; humans for nuance; model judges only with calibration against gold.
Numeric reminder for LLM serving: approximate weight memory for 7B parameters at 16 bits = 7B × 2 bytes ≈ 14 GB, before KV cache and runtime overhead

Make it operational
Resist adding a twelfth metric before the first three for LLM serving on the multi-tenant chat API have owners. This workload improves faster when a small scorecard is trusted than when a warehouse of unused plots exists.
Also pin one numeric memory from this LLM serving chapter: approximate weight memory for 7B parameters at 16 bits = 7B × 2 bytes ≈ 14 GB, before KV cache and runtime overhead That number is not decoration; it is a template for how claims about LLM serving on the multi-tenant chat API should look in design docs. Scoped specifically to LLM serving / multi-tenant chat API / evaluation.

Common mix-ups
People confuse LLM serving with neighboring buzzwords when debugging the multi-tenant chat API. Before changing prompts, ask whether the broken stage was evidence gathering, the LLM serving judgment itself, validation, or the product action. Fixing the wrong stage creates folklore (“we tried LLM serving and it failed”) that blocks the next team on the multi-tenant chat API. Scoped specifically to LLM serving / multi-tenant chat API / evaluation.

Rehearsal (serving-llms/evaluation)
Write a five-line artifact for this page: goal, inputs, check, owner, stop rule. Invent one fluent failure that the check would catch. Keep details specific to serving llms rather than generic AI advice.

Why this matters
A demo of the multi-tenant chat API looks great on three hand-picked examples of LLM serving. What does that demo refuse to tell you?
