US EditionSwitzerland Releases an Open-Weight AI Model
Apertus was trained on 1,800 languages using 15 trillion tokens and supports compliance with European copyright laws, aiming to reduce reliance on non-European AI technologies.
- Switzerland launched Apertus, an open-source AI model, on Monday to offer an alternative to proprietary systems like ChatGPT and Claude.
- The launch followed concerns over dominant AI opacity, data privacy scandals, and regulatory pressure, including the EU’s AI Act scrutiny.
- Apertus was developed collaboratively by Swiss public institutions using supercomputing resources, includes over 1,800 languages, and supports commercial and research integration.
- The model comes in two configurations—one with 8 billion parameters and another with 70 billion—and was pretrained on 15 trillion tokens sourced from public datasets, while fully complying with EU copyright regulations and honoring AI data exclusion requests.
- This launch signals Switzerland’s move towards sovereign, trustworthy AI and may encourage global collaboration and greater transparency in AI development.

Switzerland releases an open-weight AI model
Switzerland launched an open-source model called Apertus on Monday as an alternative to proprietary models like OpenAI’s ChatGPT or Anthropic’s Claude, reports SWI as spotted by Engadget. The model’s source code, training data, model weights, and detailed development process are available on the AI model platform HuggingFace. Apertus, which is Latin for “open,” was designed to “set a new baseline for trustworthy and globally relevant open model…
Switzerland Launches Apertus: Transparent Open-Source AI Model
In a move that underscores Switzerland’s longstanding commitment to data sovereignty and transparency, the country has unveiled Apertus, a groundbreaking open-source artificial intelligence model designed with privacy at its core. Developed collaboratively by public institutions including the Swiss Federal Institute of Technology Lausanne (EPFL), ETH Zurich, and the Swiss National Supercomputing Centre (CSCS), Apertus represents a national effor…
Swiss launch open source AI model as “ethical” alternative to big US LLMs
In January, assumptions around AI were shaken up by DeepSeek, a small Chinese company that nobody had heard of. This week it was Switzerland’s turn to stir things up. Apertus (Latin for ‘open’) is a brand new large language model (LLM) that its creators, a group of Swiss universities in collaboration with the Swiss National Supercomputing Centre (CSCS), claim is one of the most powerful open-source AI platforms ever released. Benchmarked as roug…
A consortium of Swiss research institutes has published Apertus, a family of language models designed to provide a transparent and data protection-compliant alternative to commercial systems such as ChatGPT. The project focuses on traceability and multilingualism. The article Swiss AI Initiative introduces with Apertus completely open language model first appeared on THE-DECODER.de.
The EPFL (École polytechnique fédérale de Lausanne), ETH Zurich and the Swiss supercomputing centre CSCS have presented a language model called Apertus, which they developed. The name of the model stands for "open" in Latin. It emphasizes an essential feature of the model: the entire development process, including architecture, model weights and training data and methods, is freely accessible and comprehensively documented.
