新素材社会热点 For more than a month, the world has been very excited about a new AI model called DeepSeek-R1. The company behind it, also called DeepSeek, is a business based in Hangzhou, Zhejiang.
The new AI first appeared on Jan. 20. In just one week, it beat OpenAI's ChatGPT and became number one free application(应用) in the App Store.
What is so special about it?
According to DeepSeek, the new AI model is as good at difficult activities like maths 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 US dollars(40.58 million yuan) to make. That is way less than the 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(RL,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(开源的). 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 better for everyone, said Liang Wenfeng, who set up DeepSeek.
