zeekay a30ff37468 Restore the Qwen names a blog rewrite erased
b3b6eb0 ran a find-and-replace over the posts forked from the QwenLM
blog that turned "Qwen2" and "Qwen2.5" into "zen": Qwen2-57B-A14B read
as zen7B-A14B, Qwen2-72B as zen-72B, Qwen2AudioForConditionalGeneration
as a class that does not exist, and links such as
github.com/QwenLM/Qwen2 and the qianwen-res image paths pointed at
nothing. Every token is put back from the original post, aligned
against the rewritten one: 536 lines across 29 posts, and 116 of the
example files under public/cases.

These 44 posts are about another lab's releases and now say so with
"upstream: true" in their frontmatter. Two Zen posts lose the
base-model names they carried, and the Zen 3 post stops calling itself
the next generation.

Previously, we opensourced a series of Qwen1.5 model ranging from 0.5 to 110 billion parameters. Now, we release a larger model, Qwen-Max-0428. Qwen-Max-0428 is an instruction-tuned model for chat service. Very recently, it is available via [Chatbot Arena](https://chat.lmsys.org/) and it has now become the top-10 in the leaderboard. Furthermore, our evaluation of MT-Bench also demonstrates that the new model outperforms our previous largest model Qwen1.5-110B-Chat.

We provide a demo of chat service of Qwen-Max-0428 ([link](https://huggingface.co/spaces/Qwen/Qwen-Max-0428)) in Hugging Face Spaces:

It is also accessible through the official DashScope API ([link](https://dashscope.aliyun.com)). Additionally, now the DashScope API is compatible with the OpenAI API format. Below is an example of usage:
```python
from openai import OpenAI
client = OpenAI(
api_key="$your-dashscope-api-key",
base_url="https://dashscope.aliyuncs.com/compatible-mode/v1"
)
completion = client.chat.completions.create(
model="qwen-max",
messages=[{'role': 'system', 'content': 'You are a helpful assistant.'},
{'role': 'user', 'content': 'Tell me something about large language models.'}]
)
print(completion.choices[0].message)
```
This model is available in our web service and APP ([link](https://tongyi.aliyun.com/qianwen/), only accessible in mainland China). Enjoy!
