Switzerland launches Apertus-8B and 70B, fully open multilingual LLMs
The Swiss AI Initiative launched Apertus-8B and Apertus-70B, fully open multilingual LLMs trained on 15T tokens covering more than 1,800 languages. The release stands out for full openness (weights, data recipe, and training transparency) and unusually broad language coverage from a national effort.
