Aleph Alpha, a German lab, has released Kolibri, a sovereign open-weight model with 78B parameters and 3.46B active parameters, capable of handling up to 1M tokens of context. Kolibri demonstrates performance comparable to models with up to four times its active parameter count, such as Nemotron 3 Super, across various tasks including math, coding, grounding, and long-context applications. This release highlights European efforts in developing open models.
