Aleph Alpha releases Kolibri-1, a 78B MoE model with 1M context

On October 3, 2026, Aleph Alpha released an open-weight model called Kolibri, which the company positions as a "sovereign" model. The release first surfaced at 17:36 that day, when a Hacker News thread linked to an Aleph Alpha blog post titled "Kolibri has landed." That thread drew 171 points and 29 comments, but it disclosed nothing about model size, benchmark results, or licensing.

Roughly an hour later, at 18:43, a second Hacker News post in the AI section picked up the same story, describing Kolibri as Germany's new sovereign AI model and pointing to a third-party blog write-up rather than the company's own page. That discussion collected 160 points and 91 comments. Neither of the early threads included concrete specifications.

By 19:44 the details were filled in. A post on the r/LocalLLaMA subreddit, titled "Aleph Alpha releases Kolibri-1: 78B MoE with 1M context," identified the model as Kolibri-1, with 78B total parameters and 3.46B active parameters in an MoE architecture, a context window of up to 1M tokens, and an Apache 2.0 license. The post cited Aleph Alpha's official X account, linked to a technical report, and noted that the model was already available on Hugging Face.

As of these reports, Aleph Alpha has published a technical report and made the model downloadable, and the community discussion has settled on the Kolibri-1 specifications. None of the material includes benchmark scores or performance figures.
