# 雅意大模型 |
|
|
|
## 介绍 |
|
|
|
[雅意大模型](https://www.wenge.com/yayi/index.html)在百万级人工构造的高质量领域数据上进行指令微调得到,训练数据覆盖媒体宣传、舆情分析、公共安全、金融风控、城市治理等五大领域,上百种自然语言指令任务。雅意大模型从预训练初始化权重到领域模型的迭代过程中,我们逐步增强了它的中文基础能力和领域分析能力,并增加了多轮对话和部分插件能力。同时,经过数百名用户内测过程中持续不断的人工反馈优化,我们进一步提升了模型性能和安全性。 |
|
|
|
通过雅意大模型的开源为促进中文预训练大模型开源社区的发展,贡献自己的一份力量,通过开源,与每一位合作伙伴共建雅意大模型生态。 |
|
|
|
*News: 🔥 雅意大模型已开源基于 LLaMA 2 的中文优化模型版本,探索适用于中文多领域任务的最新实践。* |

# YaYi |
|
|
|
## Introduction |
|
|
|
[YaYi](https://www.wenge.com/yayi/index.html) was fine-tuned on millions of artificially constructed high-quality domain data. This training data covers five key domains: media publicity, public opinion analysis, public safety, financial risk control, and urban governance, encompassing over a hundred natural language instruction tasks. Throughout the iterative development process of the YaYi, starting from pre-training initialization weights and progressing to domain-specific model, we have steadily enhanced its foundational Chinese language capabilities and domain analysis capabilities. We've also introduced multi-turn conversation enhancements and integrated various plug-in capabilities. Furthermore, through continuous manual feedback and optimization from hundreds of users during the internal testing phase, we've meticulously refined the model's performance and security. |
|
|
|
By open-sourcing the YaYi model, we will contribute our own efforts to the development of the Chinese pre-trained large language model open-source community. Through this open-source initiative, we seek to collaborate with every partner to build the YaYi model ecosystem together. |
|
|
|
*News: 🔥 YaYi has open sourced the Chinese optimization model version based on LLaMA 2 to explore the latest practices suitable for Chinese multi-domain tasks.* |
