Hack Apertus

Sovereign multilingual solutions — built by the community

Start: Q3/4 2026

Public institutions and private organisations alike process thousands of sensitive documents every year — asylum applications, medical records, legal contracts, internal communications, customer data. Most rely on cloud-based AI tools that route this data through external infrastructure, creating compliance exposure under Switzerland’s FADP and the EU AI Act.

Hack Apertus creates replicable blueprints for AI adoption across industries and public administrations. Interdisciplinary academic and professional teams worldwide source and curate datasets across text, image, and voice, fine-tune Apertus 8B v1.5, and build open, on-premise use case solutions with public and private sector partners.
All outputs, including datasets, fine-tuned models, and Docker images, are published as open commons and feed back to the Swiss AI Initiative as training data for next Apertus iterations.
