EUROPA, the EU's open AI model, is aiming for nearly 1 trillion parameters

AnnouncementModelNov 15, 2026

Domyn has run training trials for EUROPA, the EU's open AI model, on the JUPITER supercomputer in Jülich, Germany. The test setup has 951.9 billion parameters, exceeding the European Commission's 400 billion minimum, with 32.8 billion active per token under a mixture-of-experts design. Domyn raised throughput from 90 to 1,293 tokens per second per GPU. Weights are unreleased; no launch date was given. The European Commission and EuroHPC Joint Undertaking named the consortium winner in June.

Why it matters

Domyn, an Italian company leading the EUROPA consortium, has completed training trials for the European Union's planned open AI model on JUPITER, a public supercomputer in Jülich, Germany. The European Commission and the EuroHPC Joint Undertaking selected the consortium in June through the Frontier AI Grand Challenge, a contest meant to produce an open frontier model usable by public authorities, researchers and businesses across all official EU languages. Domyn's technical post describes a mixture-of-experts design with a total parameter count well beyond the Commission's minimum, though only a fraction is active per token. The company reports large throughput gains on shared scientific hardware not built for AI training, and says it will release the model's weights and training details at launch, without giving a date. The trials signal progress but leave the full training run and release timing unresolved.
