  ## Overview

  Qwen3-14B is a Qwen3 dense model with hybrid thinking and non-thinking modes.
  Intel Xeon 6 CPU serving was validated with BF16.

  ## Prerequisites

  - Hardware: Intel Xeon 6 CPUs
  - vLLM >= 0.8.5

  ### pip (Intel Xeon 6 CPUs)

  Follow the [CPU pre-built wheels](https://docs.vllm.ai/en/latest/getting_started/installation/cpu/#pre-built-wheels)
  installation instructions.

  ### Docker (Intel Xeon 6 CPUs)

  ```bash
  docker pull vllm/vllm-openai-cpu:latest-x86_64
  ```

  ## Intel Xeon 6

  Choose tensor parallelism based on the system topology; the recipe does not
  prescribe a fixed TP/DP layout or hard-code NUMA node IDs.

  ```bash
  vllm serve Qwen/Qwen3-14B
  ```

  Docker:

  ```bash
  docker run \
    --privileged --ipc=host -p 8000:8000 \
    -v ~/.cache/huggingface:/root/.cache/huggingface \
    vllm/vllm-openai-cpu:latest-x86_64 Qwen/Qwen3-14B \
    --tensor-parallel-size 1 \
    --enable-auto-tool-choice \
    --tool-call-parser hermes
  ```

  ## Configuration Notes

  - TP/DP values and explicit CPU bindings are intentionally not prescribed.
  - The `qwen3` reasoning parser is available in vLLM 0.9.0 and later.

  ## Runtime and Platform Tuning

  The following settings are intentionally not prescribed as portable CPU model
  defaults because they depend on the workload, hardware, or runtime environment:

  - `--max-num-batched-tokens`: scheduler/throughput tuning.
  - `--max-num-seqs`: concurrency and scheduler-capacity tuning.
  - `--gpu-memory-utilization`: platform memory-budget tuning.
  - `--no-enable-prefix-caching`: workload/benchmark cache-policy tuning.
  - `VLLM_ENGINE_ITERATION_TIMEOUT_S`: operational runtime timeout.

  These settings may still appear in validated hardware-specific overrides. Tune
  them at deployment time based on platform resources, workload shape, and
  latency/throughput goals.
