嘿，大家好！这里是一个专一于AI自动体的频道！
首先，让咱们来聊聊LLM。这些模型经过在海量数据集上预训练，曾经展现出了惊人的才干，无论是了解还是生成自然言语，它们都能做得很好。但疑问来了，这些模型的规模和训练老本都很高，这让它们在实践运行中有点不实际践。
这时刻，MoA退场了！MoA经过应用多个LLM的群体长处，提供了一个翻新的处置打算。构想一下，假设每个自动体都能奉献自己的一份力气，那么最终的输入结果将会如许弱小！
MoA的结构就像是一个分层的修建，每一层都有多个LLM自动体。每个自动体都会处置上一层的输入，而后生成更精细的照应。这个环节会不时迭代，直到发生一个最终的、弱小的输入。
这种结构的好处在于，LLM之间有一种自然的单干性。钻研标明，当LLM能够参考其余模型的输入时，它们会发生更高品质的照应，哪怕这些辅佐照应的品质低于模型独立输入的品质。
Together.ai就是MoA的一个典型例子。他们开发的Together MoA在AlpacaEval 2.0上的得分高达65.1%，超越了之前上游的GPT-4o的57.5%。这不只仅是一个数字的胜利，更是MoA方法在实践运行中的成功证实。
MoA的长处不只仅在于功能的优化，还在于老本效益和灵敏性。经过经常使用多个开源模型并优化层数和自动体的数量，MoA能够在坚持高功能的同时，老本也愈加可控。
Together的MOA框架曾经开源了~ ，上方是示例代码
