🤖Soofi S Debuts: Open-Source German Language Model

German AI Just Got a Major Boost

TL;DR

A German research group releases Soofi S, an open-source language model that outperforms rivals in both English and German benchmarks. It's trained to handle long inputs efficiently, making it a game-changer for multilingual tasks.

Soofi S is the latest addition to the AI landscape, boasting impressive performance across multiple languages. Trained on Deutsche Telekom’s cloud infrastructure with a focus on efficiency, this model stands out due to its hybrid architecture that activates only 3.2 billion parameters per token from a total of 31.6 billion. This makes it ideal for handling very long inputs without sacrificing speed or quality. Developers working in multilingual environments will find Soofi S particularly useful. Its superior performance on German benchmarks and English tasks, along with its ability to maintain throughput at high-context lengths, positions it as a strong contender for applications requiring robust language processing capabilities. The model was trained using 27 trillion tokens across three phases, with the data mix shifting towards higher-quality sources and more German-language content. It achieved scores of 73.8% on HumanEval and 84.2% on the German MBPP variant, significantly outperforming previous leaders like OLMo 3 32B and Apertus 70B.
