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

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.

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:

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)...

This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social visibility and check back later, or deploy to Inference Endpoints (dedicated) instead.
