Soofi: Sovereign AI from Europe​

Soofi (Sovereign Open Source Foundation Models) is a German and European project for the development of sovereign AI foundation models. Leading research institutions, universities, and AI start-ups are working together on open foundation models that address European requirements for transparency, traceability, and technological sovereignty. The consortium is coordinated by the German AI Association (KI-Bundesverband). The project is funded by the Federal Ministry for Economic Affairs and Energy (BMWE).​



Soofi S is the first foundation model in the Soofi model family and is designed for the traceable and efficient use of AI in industrial application scenarios. The open-source model forms the foundation for future, larger Soofi models – including specialized variants for multimodal and industrial applications.​

Fraunhofer in the Soofi Consortium for Sovereign AI

Two institutes from the Fraunhofer Society are involved in the development of Soofi S: the Fraunhofer Institute for Integrated Circuits IIS and the Fraunhofer Institute for Intelligent Analysis and Information Systems IAIS. Both institutes contribute their extensive expertise in artificial intelligence, natural language processing, and large language models to the project, with the goal of developing high-performance European foundation models.​

 

Fraunhofer IIS Expertise for Soofi S

Fraunhofer IIS makes key contributions to the further development of Soofi S, particularly in the areas of post-training, evaluation, and domain-specific optimization.

 

Strengths: Knowledge, Reasoning, and Coding

Soofi S is being optimized for complex problem-solving, agentic systems, and the processing of large volumes of information. A key focus lies on expanding core model capabilities: profound general and domain-specific knowledge, complex multi-step reasoning, support for coding and agent-based systems, as well as the processing of large context volumes. Its focus on German and English, along with precise adherence to user instructions, ensures strong practical usability.

 

Optimization for Productive Applications

Through its modern post-training pipeline, Fraunhofer IIS improves the quality, reliability, and safety of Soofi S. At the same time, capabilities such as logical reasoning, coding, and tool use are being specifically expanded. Current development efforts are focused on adapting the model to industry-relevant data, modalities, and specific use cases.

 

Quality Made Measurable

Extensive evaluations in the areas of language, mathematics, natural sciences, coding, tool use, and safety ensure the performance of Soofi S and provide the foundation for its continuous further development.
