<div class="ce-paragraph cdx-block ce-paragraph--left"><span md-inline="plain" class="md-plain" style="box-sizing: border-box;">你肯定被“大模型”这个词刷过屏：有人晒和 AI 畅聊的截图，短视频里 AI 一分钟写出论文，甚至连你用的各种 App 都在说接入了大模型……</span><span md-inline="softbreak" class="md-softbreak" style="box-sizing: border-box;">
</span><span md-inline="plain" class="md-plain" style="box-sizing: border-box;">听起来特别高深,但说实话，大模型并不神秘。它学识渊博，但它没有自我意识而且有时候会胡说八道。</span><span md-inline="softbreak" class="md-softbreak" style="box-sizing: border-box;">
</span><span md-inline="plain" class="md-plain" style="box-sizing: border-box;">今天，我们就用最通俗的大白话，来解释一下大模型！</span></div>

</span><span md-inline="plain" class="md-plain" style="box-sizing: border-box;">它在出厂前，人们就已经给它输入了互联网上几乎所有公开的人类文字（几十万亿字）。当你给它一个开头，它就能根据数学概率，一个词一个词地给你推测出一个完整的回答。</span></div>

</span><span md-inline="plain" class="md-plain" style="box-sizing: border-box;">所以当大模型读过无数个故事后，你给它一句话：“我买的苹果，一个很甜，一个坏了。”你问它“我买的什么？”它不仅回答“苹果”，还能顺带推理出坏了几个。</span><span md-inline="softbreak" class="md-softbreak" style="box-sizing: border-box;">
</span><span md-inline="plain" class="md-plain" style="box-sizing: border-box;">这种“举一反三”的能力，就是大模型最让人震撼的地方。</span></div>
