### What this PR does / why we need it?
Main updates include:
- update model IDs and default model paths in serving / offline
inference examples
- adjust some command snippets and notes for better copy-paste usability
- replace `SamplingParams` argument usage from `max_completion_tokens`
to `max_tokens`(**Offline** inference currently **does not support** the
"max_completion_tokens")
``` bash
Traceback (most recent call last):
File "/vllm-workspace/vllm-ascend/qwen-next.py", line 18, in <module>
sampling_params = SamplingParams(temperature=0.6, top_p=0.95, top_k=40, max_completion_tokens=32)

- fix **Qwen3-reranker** example usage to match the current **pooling
runner** interface and score output access
``` python
model = LLM(
model=model_name,
task="score", # need fix
hf_overrides={
"architectures": ["Qwen3ForSequenceClassification"],
"classifier_from_token": ["no", "yes"],
```
--->
``` python
model = LLM(
model=model_name,
runner="pooling",
hf_overrides={
"architectures": ["Qwen3ForSequenceClassification"],
"classifier_from_token": ["no", "yes"],
```
- modify **PaddleOCR-VL** parameter `TASK_QUEUE_ENABLE` from `2` to `1`
``` bash
(EngineCore_DP0 pid=26273) RuntimeError: NPUModelRunner init failed, error is NPUModelRunner failed, error
is Do not support TASK_QUEUE_ENABLE = 2 during NPU graph capture, please export TASK_QUEUE_ENABLE=1/0.
```
These changes are needed because several documentation examples had
drifted from the current runtime behavior and recommended invocation
patterns, which could confuse users when following the tutorials
directly.

Qwen3-Coder-30B-A3B
Introduction
The newly released Qwen3-Coder-30B-A3B employs a sparse MoE architecture for efficient training and inference, delivering significant optimizations in agentic coding, extended context support of up to 1M tokens, and versatile function calling.
This document will show the main verification steps of the model, including supported features, feature configuration, environment preparation, single-node deployment, accuracy and performance evaluation.
Supported Features
Refer to supported features to get the model's supported feature matrix.
Refer to feature guide to get the feature's configuration.
Environment Preparation
Model Weight
Qwen3-Coder-30B-A3B-Instruct(BF16 version): requires 1 Atlas 800 A3 node (with 16x 64G NPUs) or 1 Atlas 800 A2 node (with 8x 64G/32G NPUs). Download model weight
It is recommended to download the model weight to the shared directory of multiple nodes, such as /root/.cache/
Installation
Qwen3-Coder is first supported in vllm-ascend:v0.10.0rc1, please run this model using a later version.
You can use our official docker image to run Qwen3-Coder-30B-A3B-Instruct directly.

In addition, if you don't want to use the docker image as above, you can also build all from source:
- Install
vllm-ascendfrom source, refer to installation.
Deployment
Single-node Deployment
Run the following script to execute online inference.
For an Atlas A2 with 64 GB of NPU card memory, tensor-parallel-size should be at least 2, and for 32 GB of memory, tensor-parallel-size should be at least 4.
#!/bin/sh
export VLLM_USE_MODELSCOPE=true
vllm serve Qwen/Qwen3-Coder-30B-A3B-Instruct --served-model-name qwen3-coder --tensor-parallel-size 4 --enable_expert_parallel
Functional Verification
Once your server is started, you can query the model with input prompts:
curl http://localhost:8000/v1/chat/completions -H "Content-Type: application/json" -d '{
"model": "qwen3-coder",
"messages": [
{"role": "user", "content": "Give me a short introduction to large language models."}
],
"temperature": 0.6,
"top_p": 0.95,
"top_k": 20,
"max_completion_tokens": 4096
}'
