vLLM Integrates TileRT for Low-Latency Decoding
vllm_project · x · 2026-07-16
vLLM and TileRT demonstrated a concrete use case of a decoupled inference stack:
- By separating prefill and decode, the decode side can be freely swapped based on workload.
- TileRT connects to vLLM prefill via the vLLM V1 connector interface without modifying vLLM code, forking, or patching.
- It defaults to vLLM's native decode for throughput; for latency-sensitive scenarios, it can switch to TileRT decode, making it ideal for agents and real-time assistants.
- Both maintain OpenAI-compatible APIs and prefix caching, with the switch essentially being a routing-level choice.
- The text also mentions TileRT reported single-user decode speeds of roughly 618 tok/s on GLM-5.1-FP8, 8×B200 with MTP—nearly double its speed without MTP.
