Workspace and stored customer data: - hosted in Google Cloud's Zurich region (`europe-west6`), Switzerland. AI inference: - Google Vertex AI in Belgium; - Azure OpenAI in Switzerland North or Sweden Central; - processing therefore occurs in Switzerland and the EU, not exclusively in Switzerland. CASUS states that: - customer content is not used to train AI models; - inference uses zero data retention; - model providers do not perform human review of customer content; - there is no US inference for the listed production architecture.
