German Sovereignty: Aleph Alpha Open-Sources Weights of 78B Parameter Kolibri Model

The European continent is attempting to counter the American proprietary monopoly with its own open architecture. On October 4, 2026, German firm Aleph Alpha confirmed the global release of its flagship bilingual model `Kolibri`, featuring a Mixture-of-Experts (MoE) architecture. The model contains 78.1 billion parameters, with 3.46 billion active per token.

Aleph Alpha published the full weights under the open Apache 2.0 license, boasting support for a context window of up to 1 million tokens and pretraining on 20 trillion tokens. The central thesis of the release is sovereign artificial intelligence tailored for regulated European industries. German automotive manufacturers, financial institutions, and the public sector gain a powerful foundation for fully local (on-premise) deployment. This step delivers a palpable blow to US hyperscalers’ business models within the EU: Europe’s enterprise sector is increasingly betting on its own robust open weights to prevent confidential information leaks to American cloud servers.
