大语言模型（LLM）的进化树，学习LLM看明白这一张图就够了

近期大语言模型迅速发展，让大家看得眼花缭乱，感觉现在LLM的快速发展堪比寒武纪大爆炸，各个模型之间的关系也让人看的云里雾里。最近一些学者整理出了 ChatGPT 等语言模型的发展历程的进化树图，让大家可以对LLM之间的关系一目了然。

最重要的进化树图：

进化的树图

现代语言模型的进化树追溯了近年来语言模型的发展,并强调了一些最著名的模型。同一分支上的模型关系更近。基于Transformer的模型显示为非灰色颜色:仅解码器模型显示为蓝色分支,仅编码器模型显示为粉红色分支,而编码器-解码器模型显示为绿色分支。时间轴上模型的垂直位置代表其发布日期。开源模型由实心方块表示,而闭源模型由空心方块表示。右下角的堆叠条形图显示来自各公司和机构的模型数量。

然后是按年进化的动图，主要内容和上图相同。

趋势

a) 仅解码器模型在语言模型的发展中逐渐占主导地位。在语言模型发展的早期阶段，仅解码器模型不如仅编码器模型和编码器-解码器模型流行。然而，在2021年之后，随着改变游戏规则的语言模型GPT-3的推出，仅解码器模型经历了显著的繁荣。与此同时，在BERT带来的初始爆炸性增长之后，仅编码器模型逐渐开始消失。

b) OpenAI在语言模型领域始终保持领先地位，无论当前还是未来。其他公司和机构正在努力追赶OpenAI开发可与GPT-3和当前的GPT-4相媲美的模型。这一领先地位可归因于OpenAI即使在最初并不广泛认可的情况下也坚定地坚持其技术路线。

c) Meta对开源语言模型做出了重大贡献，并促进了语言模型的研究。在考虑对开源社区的贡献时，特别是与语言模型相关的贡献，Meta作为最慷慨的商业公司之一脱颖而出，因为Meta开发的所有语言模型都是开源的。

d) 语言模型表现出倾向于闭源的趋势。在语言模型发展的早期阶段(2020年之前)，大多数模型都是开源的。然而，随着GPT-3的推出，公司越来越倾向于闭源其模型，如PaLM、LaMDA和GPT-4。因此，学术研究人员更难进行语言模型训练的实验。因此，基于API的研究可能成为学术界的主流方法。

e) 编码器-解码器模型仍然具有前景，因为这种体系结构仍在积极探索中，并且大多数都是开源的。Google对开源编码器-解码器架构做出了重大贡献。然而，仅解码器模型的灵活性和多功能性似乎使得Google坚持这一方向的前景不太乐观。

总之，仅解码器模型和开源模型在近年来占据主导地位，而OpenAI和Meta在推动语言模型创新和开源方面做出了重大贡献。与此同时，编码器-解码器模型和闭源模型也在一定程度上推动了发展。各家公司和机构在技术发展路径上面临不同的前景。
