Aleph Alpha open-sources German sovereign model Kolibri-1, free to try in browser

Aleph Alpha open-sourced its Kolibri-1 weights on German Unity Day, and third party Tesseracted Labs has hosted it for free browser-based trials with no GPU or signup, including optional Brave Search grounding.

In the quote thread, Jonas Andrulis recalls an early 2021 finding on multilingual LLMs: English-first models default to American cultural context even when addressed in a foreign language — ask one in German about its favorite sports team and it answers baseball or American football. He poses the question of what the most authentically German answer from a truly sovereign German model would look like.
