These days, DeepSeek has received a lot of attention on the Internet. So what is DeepSeek It’s a Chinese AI company founded by a man called Liang Wenfeng on July 17, 2023. The team of researchers have studied in the top universities in China and have no oversea (海外的) educational background, and most of them are under 34 years old. They are also very good at math, physics and coding (编程). The company works on AI, especially big models (模型). Think of it like building a super smart brain that can think and solve problems like humans (this is called AGI).
On January 20, 2025, DeepSeek made a new AI called DeepSeek-R1. It can help people find information and summarize it, solve math problems, write code, and answer questions like top models such as OpenAI’s ChatGPT-40. The whole world was completely surprised, because it cost much less to build. It only took the team about $5.58 million (1/70 of Open AI’s cost) and about 50 000 computer chips, and 647 days to create it. This shows that good ideas can beat big money. On its first day online, over 19 000 programmers around the world started projects to study it. Even a top scientist in Meta (a famous US tech company) said, “This kind of free AI could change the world.”
As a DeepSeek engineer said, “We want AI to be a friend, not something only rich people can use.” With R1, China tells the world that great things come from new ideas and hard work, not just money.
