Apertus: the Swiss AI model we are bringing to Helvira

Apertus is an open, multilingual and transparent language model born from Swiss research. Its aim: a modern, auditable and truly sovereign AI.

By adopting Apertus, we reduce reliance on closed solutions and strengthen data ownership. Architecture and datasets are documented, enabling audit, governance and compliance.

Helvira integrates Apertus to deliver reliable answers in French, German, Italian and English, while meeting high security and privacy expectations.

Transparency & open-source

Weights, code and training recipes are published—providing a verifiable basis for quality, security and audit. Perfect for organizations demanding traceability.

Sovereignty & Swiss hosting

Deploy and host in Switzerland to keep control of sensitive data, lower regulatory risk and simplify local compliance.

Multilingual performance

Optimized for FR/DE/IT/EN: better grasp of local context, more accurate domain terminology and a consistent experience for international teams.

Secure Helvira integration

Built-in connectors, logging and guardrails. Fine-grained settings (contexts, roles, limits) align the AI with your processes and internal policies.

Apertus is an open academic project. Helvira integrates it to deliver a sovereign and responsible AI.
