Throughput

Also known as token throughput, aggregate throughput

In plain English

Throughput is how much total work the system gets done each second across everyone using it.

Technical definition

Throughput is the total rate at which an inference system produces tokens across all active requests.

Typical unit

tokens/second/GPU (tok/s/GPU)

Engineering details

InferenceX commonly normalizes throughput as tokens per second per GPU so systems of different sizes can be compared. Higher batching or concurrency often raises aggregate throughput because weight reads and compute are amortized across more requests, but individual users may receive tokens more slowly.

Why it matters

Maximum throughput captures only one operating point. A system can lead in tokens per second while operating at interactivity too low for a real-time product. The useful comparison is throughput at a latency or interactivity target appropriate to the workload.

How to read it in InferenceX

On an InferenceX chart, throughput is read together with interactivity across the full concurrency sweep. The Pareto frontier removes operating points that are worse on both axes.
