| <font size=4>😉ChatYuan: 元语功能型对话大模型 | General Model for Dialogue with ChatYuan | |
| <br> | |
| 👏ChatYuan-large-v2是一个支持中英双语的功能型对话语言大模型，是继ChatYuan系列中ChatYuan-large-v1开源后的又一个开源模型。ChatYuan-large-v2使用了和 v1版本相同的技术方案，在微调数据、人类反馈强化学习、思维链等方面进行了优化。 | |
| <br> | |
| ChatYuan large v2 is an open-source large language model for dialogue, supports both Chinese and English languages, and in ChatGPT style. | |
| <br> | |
| ChatYuan-large-v2是ChatYuan系列中以轻量化实现高质量效果的模型之一，用户可以在消费级显卡、 PC甚至手机上进行推理（INT4 最低只需 400M ）。 | |
| <br> | |
| 在Chatyuan-large-v1的原有功能的基础上，我们给模型进行了如下优化： | |
| - 新增了中英双语对话能力。 | |
| - 新增了拒答能力。对于一些危险、有害的问题，学会了拒答处理。 | |
| - 新增了代码生成功能。对于基础代码生成进行了一定程度优化。 | |
| - 增强了基础能力。原有上下文问答、创意性写作能力明显提升。 | |
| - 新增了表格生成功能。使生成的表格内容和格式更适配。 | |
| - 增强了基础数学运算能力。 | |
| - 最大长度token数扩展到4096。 | |
| - 增强了模拟情景能力。.<br> | |
| <br> | |
| Based on the original functions of Chatyuan-large-v1, we optimized the model as follows: | |
| -Added the ability to speak in both Chinese and English. | |
| -Added the ability to refuse to answer. Learn to refuse to answer some dangerous and harmful questions. | |
| -Added code generation functionality. Basic code generation has been optimized to a certain extent. | |
| -Enhanced basic capabilities. The original contextual Q&A and creative writing skills have significantly improved. | |
| -Added a table generation function. Make the generated table content and format more appropriate. | |
| -Enhanced basic mathematical computing capabilities. | |
| -The maximum number of length tokens has been expanded to 4096. | |
| -Enhanced ability to simulate scenarios< br> | |
