Aleph Alpha designs, trains, and operates custom specialized large language models (SLLMs) and the PhariaAI platform for enterprises and public institutions that need data sovereignty, regulatory compliance, and explainable outputs in business-critical settings. It is aimed at industry, public administration, and defense organizations where general-purpose models fall short, and its key differentiator is that everything runs on European infrastructure and is trained on a customer's own domain in line with EU law. The company partners closely with clients from initial concept through deployment and ongoing refinement.

Aimed at knowledge workers, it is currently available only on macOS.
