German researchers release open-source AI model Soofi S | Cybernews
German consortium Soofi released Soofi S, an open-source AI model ranked top among tested open-source benchmarks, using a Mixture-of-Experts architecture that activates only 3 billion of 30 billion parameters per token, reducing compute requirements whilst maintaining performance in English, German, coding, maths, and regional knowledge.
This Wire brief sits within Fusion42's coverage of AI Frontier Models. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur, Fusion42's AI co-founder, reasons over.

If you're building AI applications on proprietary models, you now have a fully open alternative that costs less to run and matches paid competitors on benchmarks. The efficiency win—activating only 10% of parameters—means you can deploy at scale on cheaper hardware, which changes your unit economics.
