魔搭Llama3 8b中文Agent智能体模型

本模型使用Llama3-8b-instruct基模型进行训练,适配中文通用场景,且支持ReACT格式的Agent调用。

模型使用

推理

# 安装依赖
pip install ms-swift -U
# 推理
swift infer --model_type llama3-8b-instruct --model_id_or_path swift/Llama3-Chinese-8B-Instruct-Agent-v1
# 部署
swift deploy --model_type llama3-8b-instruct --model_id_or_path swift/Llama3-Chinese-8B-Instruct-Agent-v1

本模型可以联合ModelScopeAgent框架使用,请参考:

模型训练信息

为了适配中文及Agent场景,我们针对语料进行了一定混合配比,训练Llama3使用的语料如下:

- COIG-CQIA:https://modelscope.cn/datasets/AI-ModelScope/COIG-CQIA/summary 该数据集包含了中国传统知识、豆瓣、弱智吧、知乎等中文互联网信息

- 魔搭通用Agent训练数据集: https://modelscope.cn/datasets/AI-ModelScope/ms-agent-for-agentfabric/summary

- alpaca-en: https://modelscope.cn/datasets/AI-ModelScope/alpaca-gpt4-data-en/summary

- ms-bench魔搭通用中文问答数据集: https://modelscope.cn/datasets/iic/ms_bench/summary

模型评测信息

评测模型 ARC CEVAL GSM8K
Llama3-8b-instruct 0.7645 0.5089 0.7475
Llama3-Chinese-8B-Instruct-Agent-v1 0.7577 0.4903 0.652

GSM8K英文数学能力下降了8个点左右,经过消融实验我们发现去除alpaca-en语料会导致GSM8K下降至少十个点以上。

Inference Examples
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.
