January 20, 2025, a Chinese tech(技术) company named DeepSeek made a new AI called DeepSeek-R1. This smart program can solve math problems, write code (代码), and answer questions like top models such as OpenAI’s GPT-4o, but it costs much less to build. The team spent only $5.58 million (1/70 of OpenAI’s cost) and used 2,048 computer chips (芯片) for two months to make it. This shows that good ideas can beat(打败) big money.
DeepSeek-R1 learns by trying many times and getting better, like how students practice maths. Other AIs need lots of prepared examples, but R1 improves by itself. In a global math test, it got 79.8% right, a little higher than OpenAI’s model. A simple version (版本) of R1 can even run on low-cost computers, helping schools and small companies.
DeepSeek-R1 is free to use and change. On its first day online, over 19,000 programmers worldwide started projects(项目) to study it. A German scientist said experiments with R1 cost $10 instead of $300 with other AIs. Even Meta (a famous U.S. tech company) top scientist said, “This kind of free AI could change the world.”
U.S. tech companies are worried. Meta planed to spend $65 billion more on AI research. Experts said China was catching up fast. A report in Nature magazine called R1 a “big step forward”, confirming that smart ideas beat expensive tools.
As a DeepSeek engineer said, “We want AI to be a friend, not something only rich people can use.” With R1, China shows the world that great things come from new ideas and hard work, not just money.
26．How much did it cost to build DeepSeek-R1
A．$2025 million. B．$5.58billion. C．$2048. D．$19,000.
27．What can we learn about DeepSeek-R1 from paragraph 2

C．It copies answers from other AIs. D．It only works with expensive tools.
28．Why did Meta plan to spend more money on AI research
A．To help Chinese companies. B．To build more computer chips.
C．To compete with DeepSeek-R1. D．To hire German scientists.
29．What does the underlined word “confirming” mean in paragraph 5
A．证实 B．竞争 C．拒绝 D．交流.
30．Which of the following can be the best title for the text
A．Competition between GPT-4o and DeepSeek-R1 B．Comparison of Chinese and American AI Models
