DeepSeek-R1 is free t use and change. On its first day nline, ver 19,000 prgrammers all ver the wrld started prjects t study it. A German scientist said experiments(实验) with RI cst $10 instead f $300 with ther Als. Even Meta(a famus U. S. tech cmpany) tp scientist said, "This kind f free AI culd change the wrld."
