Switzerland just did something no other country has done with AI – and it’s about to change everything.

While tech giants keep their AI models locked behind corporate walls, Switzerland said “hold my fondue” and released Apertus – the world’s first 100% transparent AI model. We’re talking full access to everything: the code, the training data, the documentation, even the intermediate checkpoints.

This isn’t just another AI release. This is a blueprint for how AI should be built in the public interest.

What Makes Apertus Different?

Most AI companies give you the equivalent of a black box – you can use their model, but you have no idea what’s inside. Apertus flips that script completely.

Built by Switzerland’s top institutions (EPFL, ETH Zurich, and the Swiss National Supercomputing Centre), this model comes in two flavors:

• 8-billion parameter version – perfect for smaller applications
• 70-billion parameter version – the heavy hitter for complex tasks

Both are available under a permissive open-source license, meaning you can use them for research, education, or even commercial projects. No strings attached.

The Multilingual Powerhouse

Here’s where it gets really interesting. Apertus was trained on 15 trillion tokens across more than 1,000 languages. That’s not a typo – over a thousand languages.

But here’s the kicker: 40% of the training data isn’t in English. They included languages that most AI models completely ignore, like Swiss German and Romansh. This isn’t just about building another English-first AI system – it’s about creating something truly global.

Transparency That Actually Means Something

When most companies say “open AI,” they mean you can use their API. When Switzerland says it, they mean you can see everything:

• Full architecture details – exactly how the model is built
• Complete training dataset – every piece of data used to train it
• Training process documentation – step-by-step how they did it
• Intermediate checkpoints – snapshots of the model during training

This level of transparency is unprecedented. It’s like getting the recipe, ingredients, cooking process, and even photos of every step when making a dish.

Built for the Public Good

Martin Jaggi from EPFL put it perfectly: “With this release, we aim to provide a blueprint for how a trustworthy, sovereign, and inclusive AI model can be developed.”

This isn’t about profit margins or market dominance. It’s about creating AI infrastructure that serves everyone – like highways, water systems, or electricity grids.

The model follows strict ethical guidelines:

• Swiss data protection rules
• Swiss copyright law
• EU AI Act transparency requirements
• Personal data filtering
• Website opt-out respect

Real-World Applications Starting Now

Apertus isn’t just a research project sitting on a shelf. It’s already being deployed:

Swisscom is using it on their sovereign AI platform, giving business customers immediate access.

Developers can test it during Swiss AI Weeks (running until October 5, 2025).

International users will get access through the Public AI Inference Utility.

You can download it directly from Hugging Face or access it through Swisscom’s platform. The barrier to entry? Practically zero.

Why This Matters Beyond Switzerland

This release sends shockwaves through the AI industry. While companies like OpenAI and Anthropic keep their models proprietary, Switzerland just proved you can build world-class AI in the open.

Joshua Tan from the Public AI Inference Utility called it “the leading public AI model: a model built by public institutions, for the public interest.”

It’s proof that AI can be public infrastructure rather than corporate property.

The Ripple Effect

Other countries are watching. If Switzerland can build transparent, multilingual, ethically-compliant AI models, why can’t everyone else?

This could spark a new wave of public AI development:

• Government-funded models serving citizens
• Academic institutions collaborating across borders
• Transparent AI that we can actually trust

What’s Next for Apertus?

This is just the beginning. The Swiss team plans to:

• Expand the model family
• Improve efficiency
• Develop domain-specific tools for law, health, climate, and education
• Maintain strict transparency standards

Antoine Bosselut from EPFL emphasized: “The release of Apertus is not a final step, rather it’s the beginning of a journey, a long-term commitment to open, trustworthy, and sovereign AI foundations.”

The Bottom Line

Switzerland just changed the AI game. They proved you can build powerful, multilingual AI models without sacrificing transparency or ethics.

While tech giants fight over market share with closed systems, Switzerland built something for everyone. It’s AI as public infrastructure – transparent, accessible, and designed to serve the common good.

This could be the moment we look back on as when AI development split into two paths: corporate black boxes versus transparent public infrastructure.

Which path do you think the AI industry should take? Should more countries follow Switzerland’s lead and build transparent, public AI models, or do proprietary systems serve us better?
