German AI company Aleph Alpha has introduced Kolibri, an open-weight language model designed for public authorities, industry, and other sectors with strict data control requirements. The model supports German and English and has 78 billion parameters, but activates only around 3.5 billion per token to improve computational efficiency.
The model weights are available under the Apache 2.0 license, allowing organizations to run Kolibri on their own infrastructure. Kolibri supports complex text processing, reasoning, and tool use, with a context window of up to one million tokens. The release strengthens Germany’s ambitions to help build a sovereign European AI ecosystem.
