Now the world is very interested in a new AI model. Its name is DeepSeek-R1. The company behind it, also called DeepSeek, is a business in Hangzhou, Zhejiang.
The new AI first came out on Jan. 20th, 2025. In just one week, it beat OpenAI's ChatGPT and became number one free application in the IOS App Store. What is so special about it?
According to DeepSeek, the new AI model is as good at difficult activities like math as other big-time models. But it needs much less computing power(算力) to do that. It is also the cheapest of its kind and took only about 5. 57 million dollars to make. That is way less than hundreds of millions or even billions that US businesses have to spend on making similar AI models, said Marc Andreessen, a technology expert in the US.
The achievement was largely due to an idea the scientists had while they trained it. Instead of using the traditional ways, DeepSeek mainly uses reinforcement learning(强化学习). It helps AI learn by working out the right way to do things on its own to get points. This makes 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. People can also change the code to meet their own needs. Being open-source is very important for sharing knowledge and making technology better for everyone, said Liang Wenfeng, who set up DeepSeek.

D. The importance of open-source codes.

答案： 1. C 词义猜测题。根据句意理解可知，科学家在训练它的过程中有了想法，所以此处画线词的意思是“训练”，与C项的意思相近。
2. C 细节理解题。根据第四段中的“It helps AI learn by working out the right way to do things on its own to get points.”可知，C项符合题意。
3. D 推理判断题。根据最后一段中“People can also change the code to meet their own needs. Being open-source is very important for sharing knowledge and making technology better for everyone”可知，DeepSeek-R1开放源代码能够让人工智能的应用更广泛。
4. A 主旨大意题。通读全文内容可知，本文主要介绍了来自杭州深度求索公司的DeepSeek-R1人工智能模型的面世时间、强大功能、低廉成本、技术亮点以及重大影响，故A项最符合文意。
