+# Qwen
+
+Qwen (通义千问) is a language model proposed by Alibaba Cloud[^1]. The architecture of Qwen is similar to Llama except for the bias in the attention layers.
+
+## Setup
+
+Download (from huggingface) and conver the model. By default, the model is `Qwen/Qwen-1_8B`.
+
+```sh
+python convert.py
+```
+
+This will make the `weights.npz` file which MLX can read.
+
+## Generate
+
+To generate text with the default prompt (default tokenizer is `Qwen/Qwen-1_8B`):
+
+```sh
+python qwen.py
+```
+
+To see a list of options, run:
+
+```sh
+python qwen.py --help
+```
+
+[^1]: For more details on the model see the official repo of [Qwen](https://github.com/QwenLM/Qwen) and the [Hugging Face](https://huggingface.co/Qwen).
