  description: "Best Practice for Qwen3.6-35B-A3B on Ascend NPU"
---

<Note>
This page focuses on optimal configuration and benchmark results for Qwen3.6-35B-A3B on the Ascend NPU. For environment setup, model weight download, feature configuration, and deployment instructions, etc., see the [Qwen3.6-35B-A3B Model Tutorial](/docs/hardware-platforms/ascend-npus/model-tutorials/qwen3_6_35b_a3b).

On A3 each card has 2 dies, so `--tp-size` is twice the card count; see [Ascend NPU Reference](/docs/hardware-platforms/ascend-npus/ascend_npu_reference#hardware) for details.

Use image **SGLang `>= v0.5.14`** for these NEXTN configurations. Without `--dataset-path`, `bench_serving --dataset-name random` downloads ShareGPT from Hugging Face; in offline environments, pass a local dataset path (for example a ShareGPT JSON file).

#### Benchmark

We tested it based on the `generated-shared-prefix` dataset with 90% cache hit (`repeat_rate = 0.9`):
`--gsp-system-prompt-len 58982` = `int(65536 * 0.9)` is the shared prefix portion.
`--gsp-question-len 6553` = `int(65536 * (1 - 0.9))` is the unique per-request suffix.
`--gsp-num-groups 1` keeps all requests in one prefix group for maximum cache reuse.

```bash Command
python -m sglang.bench_serving \
    --dataset-name generated-shared-prefix \
    --backend sglang \
    --host 127.0.0.1 \
