--8<-- [start:requirements]

• OS: Linux
• CPU flags: avx512f (Recommended), avx512_bf16 (Optional), avx512_vnni (Optional)

!!! tip Use lscpu to check the CPU flags.

!!! warning If deploying the pre-built images on machines without avx512f, avx512_bf16, or avx512_vnni support, an Illegal instruction error may be raised. It is recommended to build images for these machines with the appropriate build arguments (e.g., --build-arg VLLM_CPU_DISABLE_AVX512=true, --build-arg VLLM_CPU_AVX512BF16=false, or --build-arg VLLM_CPU_AVX512VNNI=false) to disable unsupported features. Please note that without avx512f, AVX2 will be used and this version is not recommended because it only has basic feature support.
