The 'Hack Apertus Online Hackathon' is the initial phase of a three-stage open-source hackathon series focused on Switzerland's open large language model, Apertus. Teams will work on red-teaming, localizing the model to Swiss dialects and values, and building early prototypes for sovereign infrastructure. The event aims to foster Apertus adoption and create open, trustworthy solutions for both public and private sectors.
