Duolingo如何利用人工智能更快地创建课程

You’ve probably heard plenty of buzz on the internet about artificial intelligence, or AI, and how it's rapidly weaving its way into the tech products you use daily. Here at Duolingo, we've been using AI for years, and we’ve recently brought the power of AI to our learners through Duolingo Max—but we’re also using AI behind the scenes to build courses faster and better than ever.

您可能在互联网上听到过很多关于人工智能（AI）的讨论，以及它是如何快速融入您日常使用的科技产品中的。在Duolingo，我们使用人工智能已有多年，最近我们通过Duolingo Max将人工智能的力量带给了我们的学习者--但我们也在幕后使用人工智能来构建比以往更快更好的课程。

The type of AI we use is called a Large Language Model (LLM), and it’s very good at predicting the most likely way to complete a string of text, like a sentence. This is what’s at work on your phone when it suggests next words to type in text messages!

我们使用的人工智能类型被称为大语言模型（LLM），它非常擅长预测完成一串文本（如句子）的最可能方式。当您的手机在短信中建议输入下一个单词时，这就是它的工作原理！

A Large Language Model “thinks” kind of like this:

大语言模型是这样 "思考 "的：

With a powerful Large Language Model in the hands of Duolingo’s teaching experts, we can generate vast amounts of content for our lessons with the click of a button.

有了Duolingo教学专家手中强大的大型语言模型，我们只需点击一下按钮，就可以为我们的课程生成大量的内容。

How AI helps us create lessons

人工智能如何帮助我们创造课程

AI is nothing new at Duolingo. In fact, we’ve been using an AI model called "Birdbrain" to make sure the exercises you see on Duolingo are at the perfect difficulty level based on your strengths and weaknesses. Until now, every single exercise chosen by Birdbrain was written, reviewed, edited, and translated by human experts who constantly think about maximizing both the entertainment and learning value of every Duolingo lesson.

人工智能在Duolingo并不是什么新鲜事。事实上，我们一直在使用一个名为 "Birdbrain "的人工智能模型来确保您在Duolingo上看到的练习都是根据您的优势和劣势而设置的完美难度。到目前为止，Birdbrain选择的每一个练习都是由人类专家编写、审核、编辑和翻译的，他们不断思考如何最大化每节Duolingo课程的娱乐和学习价值。
