Deutsche Telekom has released Soofi S 30B-A3B, a sovereign, open-source Mixture-of-Experts foundation model optimized for German and English. Built on the German Industrial AI Cloud, the model activates only 3 billion of its 30 billion parameters per token to maintain near-constant inference cache as context grows.

  • Pretrained on roughly 27 trillion tokens with up-weighted German data.
  • Matches dense 14 to 27B models on aggregate English and German benchmarks.
  • Achieves the best code aggregates in both languages among 17 open base models.
  • Outperforms every European sovereign baseline, including those with far larger active parameters.
  • Obtains the highest English and German evaluation scores among fully open models, ahead of Olmo 3 32B and Apertus 70B.

The release includes weights, intermediate checkpoints, data accounting, hyperparameters, and training code under highly permissive terms.
