vLLM has been adapted to work on ARM64 CPUs with NEON support, leveraging the CPU backend initially developed for the x86 platform.

ARM CPU backend currently supports Float32, FP16 and BFloat16 datatypes.

!!! warning
    There are no pre-built wheels or images for this device, so you must build vLLM from source.
