European Tech Sovereignty: Aleph Alpha signs itself into CohereBackground
Samuel Weinbach co-founded Aleph Alpha, the German AI company, in 2019 with Jonas Andrulis, and has served as its co-chief research officer since. His scientific work spans tokenisation, language-model training, explainability and image generation. Aleph Alpha itself was founded in Heidelberg and built its reputation on European, GDPR-aligned large language models before the Cohere combination.
Once Aleph Alpha's combination with Cohere closes, Weinbach is set to become Cohere's chief research officer, advancing the combined firm's research and technology programme. The appointment keeps Aleph Alpha's original research leadership inside the merged company rather than seeing it depart at the point of combination.
