## {model_name}
ChatGLM-6B 是开源中英双语对话模型,本次训练基于ChatGLM-6B 的第一代版本,在保留了初代模型对话流畅、部署门槛较低等众多优秀特性的基础之上开展训练。
本项目经过多位网友实测,中文总结能力超越了GPT3.5各版本,健康咨询水平优于其它同量级模型,且经优化目前可以支持无限context,远大于4k、8K、16K......,可能是任何个人和中小企业首选模型。
*首先,用40万条高质量数据进行强化训练,以提高模型的基础能力;
*第二,使用30万条人类反馈数据,构建一个表达方式规范优雅的语言模式(RM模型);
*第三,在保留SFT阶段三分之一训练数据的同时,增加了30万条fitness数据,叠加RM模型,对ChatGLM-6B进行强化训练。
通过训练我们对模型有了更深刻的认知,LLM在一直在进化,好的方法和数据可以挖掘出模型的更大潜能。
训练中特别强化了中英文学术论文的翻译和总结,可以成为普通用户和科研人员的得力助手。
