Qwen3-1.7B

This version of Qwen3-1.7B has been converted to run on the Axera NPU using w8a16 quantization.

This model has been optimized with the following LoRA:

Compatible with Pulsar2 version: 5.2

For those who are interested in model conversion, you can try to export axmodel through the original repo : https://huggingface.co/Qwen/Qwen3-1.7B

Pulsar2 Link, How to Convert LLM from Huggingface to axmodel

AXera NPU LLM Runtime

Convert the original Huggingface Qwen3-1.7B to axmodel, and then apply the w8a16 quantization to get the final axmodel for axllm runtime.

export FLOAT_MATMUL_USE_CONV_EU=1 # only support AX650, for better performance, please set this env var before running the conversion command.

# context window size 2048, prefill length 1024

How to use

安装 axllm

方式一：克隆仓库后执行安装脚本：

git clone -b axllm https://github.com/AXERA-TECH/ax-llm.git
cd ax-llm
./install.sh

方式二：一行命令安装（默认分支 axllm）：

curl -fsSL https://raw.githubusercontent.com/AXERA-TECH/ax-llm/axllm/install.sh | bash

方式三：下载Github Actions CI 导出的可执行程序（适合没有编译环境的用户）：

如果没有编译环境，请到： https://github.com/AXERA-TECH/ax-llm/actions?query=branch%3Aaxllm 下载 最新 CI 导出的可执行程序（axllm），然后：

chmod +x axllm
sudo mv axllm /usr/bin/axllm

模型下载（Hugging Face）

先创建模型目录并进入，然后下载到该目录：

mkdir -p AXERA-TECH/Qwen3-1.7B
cd AXERA-TECH/Qwen3-1.7B
hf download AXERA-TECH/Qwen3-1.7B --local-dir .

Okay, the user asked, "Who are you?" I need to respond appropriately. Let me think.

First, I should introduce myself clearly. My name is Assistant, but I should mention that I'm an AI developed by Alibaba Group. That's important to set the context.

Next, I should explain my purpose. I'm here to help with questions, provide information, and assist with tasks. It's important to highlight that I can't perform actions like accessing external data or making decisions, but I can offer help based on the information I have.

I should also mention that I'm designed to be helpful and friendly, but I can't replace real people. It's good to remind the user that if they have specific questions, they should ask directly.

I need to keep the tone friendly and approachable. Avoid technical jargon. Make sure the response is concise but covers all the key points. Let me check if I missed anything. Oh, maybe mention that I can help with various topics, but I can't provide personal advice. That's a good point to include.

Alright, putting it all together in a natural, conversational way.
