vLLM RBLN Plugin

This repository provides the hardware plugin that enables vLLM on RBLN NPUs, including ATOM and REBEL.

Built on top of vLLM’s Plugin System, it allows seamless integration with the vLLM ecosystem and provides high-throughput, low-latency LLM serving on RBLN hardware. Our plugin supports a wide range of popular LLMs and continues to expand to support all features enabled in vLLM, including advanced attention mechanisms.
