Overview
Aleph Alpha is a German AI company founded in 2019 in Heidelberg by Jonas Andrulis and Samuel Weinbach. It develops its own large language models — starting with the Luminous family — and positions them as sovereign alternatives that run on European infrastructure, sold to enterprises and government agencies rather than consumers. The company emphasizes transparency about the sources behind generated results and publishes open research artifacts, such as German-web classifiers, on Hugging Face. In 2026 Cohere and Aleph Alpha announced a merger under which Cohere would acquire Aleph Alpha.
