Jun 15 Apertus Mini
A set of 16 small language models released to demonstrate distillation and quantization techniques.
Developed by the Swiss AI Initiative as a collaborative effort between EPFL, ETH Zurich, and CSCS. Open weights, open data, open science.
Training data, code, weights, methods, and alignment principles — all documented and reproducible. Apertus is to AI as Open is to Source.
Built to meet EU AI Act requirements: the model respects opt-outs, removes PII, prevents memorization. A global foundation to build on.
Competitive with top open models at an equivalent scale of 8B and 70B parameters. Multilingual from day one — trained on 1000+ languages.
