Monday morning AI and cyber briefing. Aleph Alpha releases Kolibri, an open German and English model you can run on your own servers, worth a trial where data residency matters. Anthropic's red team…
Aleph Alpha is a Heidelberg company that builds AI mostly for governments and heavily regulated industries in Europe.
On Saturday, which was German Unity Day, it published a model called Colibri as open weights.
That means the company has shared the finished model itself, the files that make it work on Hugging Face, the big public library for AI models, so anyone can grab a copy, host it on their own hardware, and adapt it.
The license is Apache two, a standard open license that lets a business use it commercially without asking.
Although it covers the model files rather than the training code.
It's also what's called a mixture of experts, where only a small slice of the model does the work for each word, so it's cheaper to run than its overall size suggests.
To host it yourself, you need one top-end data center graphics card or two from the previous generation.
The company's own tests look strong on maths and coding, but nobody independent has checked them yet.
And one outside comparison puts it ahead of last spring's open models and behind today's best.
It also arrives two weeks after Aleph Alpha agreed to combine with Cohere, the Canadian business AI company.
I want Tim on, who should actually spend a week testing this, because sovereign is a word that gets used very loosely.
And that's the real value.
It isn't going to beat the best American or Chinese models on raw ability, and nobody outside the company has measured it properly yet.
If you're a public body or a regulated firm with German language work and a rule that data stays in the country, put it in your next round of trials next to the open models you already use and test it on your own documents.
If you don't have that requirement, I'd note the name and carry on as you are.
