With this milestone, Europe enters the global league of high-performance computing.

Officially ranked as Europe's most powerful supercomputer and the fourth fastest worldwide, JUPITER combines unmatched performance with a strong focus on sustainability. The system runs entirely on renewable energy and features cutting-edge cooling and energy reuse, making it the world's most energy-efficient supercomputer module, as confirmed by its number-one position on the Green500 ranking.

With computing power exceeding one exaflop, JUPITER will transform science, innovation, and policymaking across Europe. Researchers will now be able to run climate and weather models at kilometre-scale resolution, enabling much more precise forecasts of extreme events such as heatwaves, heavy storms, and floods.

JUPITER will support the development and deployment of AI solutions; its supercomputing capability will support the future AI Factory (JAIF) announced in March 2025, which will train cutting-edge large language models (LLMs) for generative AI and next-generation digital technologies.
