After #Teuken7b and #Olmo2, Apertus is the next big jump in capabilities and performance of #FOSS #LLMs, while also improving #epistemicresilience and #epistemicautonomy with its multilingual approach.

I believe that especially for sensitive areas like #education, #healthcare, or #academia, there is no alternative to fully open #AI models. Everybody should start building upon them and improving them.

What would it mean to build #AI as a commons, held in trust, accountable to communities—not owned, but stewarded?

Where do we see initiatives like #PublicAI fitting into this? openfuture.eu/our-work/ai-and-…

What more could we imagine together?
