Kolibri Has Landed: A Sovereign Open-Weight Model

Aleph Alpha released Kolibri, a 78-billion-parameter English-German open-weight language model with only 3 billion active parameters, supporting up to 1 million token contexts and available under Apache 2.0 license. Designed specifically for sovereign, mission-critical applications in regulated sectors like public administration and aerospace, Kolibri is optimized for German language, reasoning, and math while prioritizing data sovereignty and supply-chain transparency. The model's efficient size enables on-premise deployment without requiring external data transfer, making it compliant and cost-effective for enterprise and government customers.
