Officials say the machine, powered entirely by renewable energy, is the world’s most energy-efficient supercomputer. Alekandra Przegalińska, vice rector for innovation at Koźminski University and a senior research associate at Harvard University, told TVP World that Jupiter would help Europe close the gap in the global AI race while also retaining key talent and building strategic independence in semiconductors and computing. Experts say the breakthrough will give Europe greater technological sovereignty, long dominated by the U.S. and China, and will enable advances in fields from artificial intelligence training and climate modeling to drug discovery.
