# Chuxin-1.6B-Base
## 介绍 (Introduction)
**Chuxin-1.6B-Base**是16亿参数规模的模型。Chuxin-1.6B完全基于开源数据构建,在经过超大规模数据训练后,Chuxin-1.6B在各类下游任务上具有非常强的竞争力。
**Chuxin-1.6B-1M**是基于Chuxin-1.6B-base模型在1M窗口下训练后的结果,大海捞针实验显示其具有非常强的上下文检索能力。
如果您想了解更多关于Chuxin-1.6B开源模型的细节,我们建议您参阅我们的[技术报告](https://xxxx)
**Chuxin-1.6B-Base** is a model with 1.6 billion parameters. Chuxin-1.6B is built entirely on open-source data. After being trained with large-scale data, Chuxin has very competitive capabilities in various downstream tasks.
**Chuxin-1.6B-1M** is the result of training the Chuxin-1.6B-base model with a 1M windows. Experiments such as searching for a needle in a haystack demonstrate its strong contextual retrieval abilities.
If you would like to learn more about the Chuxin-1.6B open-source model, we suggest you refer to our [technical report](https://xxxx).
## 快速使用(Quickstart)
您可以通过以下代码轻松调用:
You can easily call the model with the following code:
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("chuxin-llm/Chuxin-1.6B-Base", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("chuxin-llm/Chuxin-1.6B-Base", device_map="auto", trust_remote_code=True, bf16=True).eval()
inputs = tokenizer('蒙古国的首都是乌兰巴托(Ulaanbaatar)\n冰岛的首都是雷克雅未克(Reykjavik)\n埃塞俄比亚的首都是', return_tensors='pt')
inputs = inputs.to(model.device)
pred = model.generate(**inputs, max_new_tokens=15, do_sample=False)
print(tokenizer.decode(pred.cpu()[0], skip_special_tokens=True))
# 蒙古国的首都是乌兰巴托(Ulaanbaatar)\n冰岛的首都是雷克雅未克(Reykjavik)\n埃塞俄比亚的首都是亚的斯亚贝巴(Addis Ababa)...
```
