This shows that smart ideas are better than just spending a lot of money.DeepSeek-R1 is free to use, and people can even change it. On its first day, more than 19,000 computer experts around the world started using it. A German scientist said, “Using R1 for experiments costs only $10, but other AIs need $300.”Even a top scientist from Meta (a big U.

A report in Nature (a famous science magazine) called R1 a “big success”, showing that good ideas are more important than expensive tools.A DeepSeek engineer said, “We want AI to help everyone, not just rich people.” With R1, China shows that great things come from new ideas and hard work, not just money.22.
