Aleph Alpha

Aleph Alpha is a German AI company headquartered in Heidelberg that builds large language models for enterprise and government customers. Its Luminous family supports text and image prompts and is designed for explainability, exposing patterns learned by the model to make outputs more controllable than typical black-box LLMs. The company sells access through APIs and on-premises deployments aimed at the public sector and regulated industries in Europe. Investors include Schwarz Gruppe, SAP, Bosch and HPE; in 2026 Aleph Alpha entered merger talks with Cohere with German government support.
