TileRT

Also known as TileRT engine

In plain English

TileRT is an inference runtime built for very fast single-user generation, compiling a model into one resident program instead of many separate kernel launches.

Technical definition

TileRT is an inference engine that targets ultra-low-latency serving by abolishing the individual kernel as the unit of execution.

Engineering details

A conventional runtime dispatches a sequence of kernels for every decode step, and at very small batch sizes the launch and scheduling overhead between them dominates the arithmetic. A persistent engine kernel keeps the work resident on the accelerator instead, which is what makes the far-right end of the interactivity axis reachable at all.

Why it matters

The high-interactivity corner of the frontier is a different engineering problem from the high-throughput corner, and an engine tuned for one rarely wins the other. Recipes that reach hundreds of tokens per second per user matter for latency-critical products even when their aggregate throughput per chip is unremarkable.

How to read it in InferenceX

InferenceX reports TileRT as its own framework label and deliberately retains it in best-per-SKU views, because a curve that only survives where it dominates on throughput would drop the operating points TileRT exists to serve. Compare it at matched interactivity rather than on peak throughput alone.
