prompt = "9.11和9.8哪个数字大"  
#INT4: 
"""
要比较9.11和9.8的大小，我们可以按照以下步骤进行：

1. 首先，将两个数都转换为相同的小数形式。这里我们使用小数点前的零来方便比较。

   9.11 = 9.1100 (保留两位小数)
   9.8 = 9.8000 (保留两位小数)

2. 现在，比较这两个小数：
   - 第一位：9 和 9 相等。
   - 第二位：第一位是相同的，都是1。
   - 第三位：第一个数是1，第二个数是8，所以8 > 1。

因此，9.8大于9.11。

最终答案：9.8更大。
"""

##BF16: 
"""
要比较9.11和9.8的大小，我们可以按照以下步骤进行：

1. **直接比较**：将两个数相减：
   \[
   9.11 - 9.8 = -0.69
   \]

2. **理解结果**：-0.69表示的是一个负数。因为9.11比9.8小。

因此，9.8比9.11大。

"""once upon a time, there was a young girl named Lily who lived in a small village nestled between two mountains. She had always been fascinated by the natural world and dreamed of exploring it further.

One day, while wandering through the forest, she stumbled upon an old, mysterious book that seemed to have been written on its pages. As she read, she realized that the book contained secrets about the hidden treasures of the earth.

Lily was determined to uncover these secrets and become a true explorer. She spent hours poring over the pages, trying to understand what the author was trying to tell her.

Finally, after many days of research and study, Lily discovered the location of the treasure. It lay deep within the heart of the mountain range, guarded by powerful forces that only those with the right knowledge could reach.

With great excitement, Lily set out on her journey to find the treasure. She traveled for weeks, crossing treacherous terrain and battling fierce beasts along the way. But even as she"""

Generate the model

Here is the sample command to generate the model. We observed a larger accuracy drop in Chinese tasks and recommend using a high-quality Chinese dataset for calibration or smaller group_size like 32.

bash

auto-round \
--model  Qwen/Qwen2.5-0.5B-Instruct \
--device 0 \
--group_size 128 \
--nsamples 512 \
--bits 4 \
--iter 1000 \
--disable_eval \
--model_dtype "fp16" \
--format 'auto_gptq,auto_round' \
--output_dir "./tmp_autoround" 

Ethical Considerations and Limitations

The model can produce factually incorrect output, and should not be relied on to produce factually accurate information. Because of the limitations of the pretrained model and the finetuning datasets, it is possible that this model could generate lewd, biased or otherwise offensive outputs.

Therefore, before deploying any applications of the model, developers should perform safety testing.

Caveats and Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
