五、阅读理解。
Recently, the world has been very excited about AI models. DeepSeek - R1 is one of them. The company behind it, also called DeepSeek, is a business in Hangzhou, Zhejiang.
The new AI model first appeared on Jan. 20, 2025. In just one week, it beat OpenAI's ChatGPT and became No. 1 free application (应用程序) in the App Store in China.
According to DeepSeek, the new AI model is as good at dealing with difficult activities as other AI models. But it needs much less computing power (算力) to do that. It is also one of the cheapest of its kind.
How does DeepSeek - R1 learn? Instead of using the traditional ways, DeepSeek mainly uses reinforcement learning (RL, 强化学习). It helps the AI model learn by working out the right way to do things on its own to get points. This makes DeepSeek - R1 better at reasoning and solving hard problems.
What's more, DeepSeek - R1 is open - source (开放源代码的). Everyone is free to get a copy of its code (代码). They can also change the code to meet their own needs. "Being open - source is very important for sharing knowledge and making technology (技术) better for everyone," said Liang Wenfeng, who set up DeepSeek.

五、阅读理解。
最近，全球对人工智能模型都十分关注。深度求索 - R1（DeepSeek - R1）就是其中之一。其背后的开发公司也叫深度求索（DeepSeek），是一家位于浙江杭州的企业。
这款新的人工智能模型于2025年1月20日首次亮相。仅仅一周时间，它就超越了OpenAI的ChatGPT，成为中国应用商店（App Store）排名第一的免费应用程序。
据深度求索介绍，这款新的人工智能模型在处理复杂任务方面的能力与其他人工智能模型相当。但它完成这些任务所需的算力要少得多。它也是同类模型中成本最低的之一。
深度求索 - R1是如何学习的呢？深度求索没有采用传统的方法，而是主要运用强化学习（RL）。这种学习方式通过让人工智能模型自主找出做事的正确方法来获取分数，从而帮助它学习。这使得深度求索 - R1在推理和解决难题方面表现得更为出色。
此外，深度求索 - R1是开放源代码的。任何人都可以免费获取它的代码副本。他们还可以根据自己的需求修改代码。深度求索的创始人梁文峰表示：“开放源代码对于知识共享以及让技术更好地服务于每个人都非常重要。”
（ ）1. 第二段主要介绍了深度求索 - R1的什么特点？
