→Swiss universities launch Apertus, a fully open foundation model built for sovereign AI
Apertus is a foundation model from the Swiss AI Initiative, built jointly by EPFL, ETH Zurich, and CSCS. Training data, code, weights, and methods are all open. It comes in 8B and 70B sizes and is trained on 1,000+ languages from day one. Compliance is the headline feature: it respects opt-outs, strips PII, and prevents memorization, targeting EU AI Act requirements. The team claims performance competitive with top open models of equivalent scale, though the post does not include specific benchmark scores. A set of 16 small models called Apertus Mini was also released on June 15 to demonstrate distillation and quantization techniques.

Swiss unis drop a fully open 8B/70B model targeting EU AI Act compliance, but no benchmark scores are shown.

I clicked because "sovereign AI" plus "fully open" is a loud combo right now. Built by EPFL, ETH Zurich, and CSCS, Apertus ships with training data, code, weights, and alignment principles all public. The compliance angle is the real pitch: it respects opt-outs, strips PII, and prevents memorization — clearly aimed at EU AI Act requirements. Training on 1,000+ languages from day one is also a bolder multilingual claim than most open models make.
But I'd hold off on the excitement. The page says performance is "competitive with top open models at equivalent scale" without a single benchmark number. No MMLU, no HumanEval, no multilingual eval sets — so we can't place it against Qwen or Llama variants yet. The 16 Apertus Mini models released June 15 are about distillation and quantization demos, not performance proof.
The missing piece is scores and real-world feedback. If the ACL 2026 paper fills that in, then it's worth a real comparison.
