Ⅳ. 任务型读写。
On January 20, 2025, a Chinese tech company named DeepSeek made a new AI called DeepSeek - R1. It is free to use and change. On its first day online, more than 19000 programmers worldwide started projects to study it.
This smart program can work out math problems, write code, and answer questions like top models such as Open AI's GPT 4.0, but it costs much less to build. The team spent only 5.58 million (1/70 of Open AI's cost) and used 2048 computer chips for two months. A German scientist said experiments with R1 cost 10 instead of 300 with other AIs.
DeepSeek - R1 learns by trying many times and getting better, like how students practice math. Other AIs need lots of prepared examples, but R1 improves by itself. For example, in a global math test, it got 79.8% right, slightly higher than Open AI's model.
Experts say China is catching up fast. A report in Nature magazine called R1 a “big step forward”, proving 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.”
