- What happened
- ELMOD is a 2.7 billion parameter German language model optimized for mobile devices, matching 7B model performance on German tasks.
- Why it matters
- Matters for engineers building German-language applications on phones or edge devices with limited computational resources and memory.
- Watch out
- Paper focuses on German language specifically; results may not transfer to other languages or multilingual scenarios requiring different preprocessing.

Abstract: We present ELMOD - Efficient Language Model for On-Device Deployment - a compact (2.7B) German language model designed for efficient inference on resource-constrained hardware. ELMOD was trained on a limited computational budget (55k H100 GPU hours) using exclusively publicly available data. We developed a suite of German-specific data pre-processing, which differ from English-oriented counterparts in their handling of morphological variation, compounding, and orthographic conventions. Furthermore, we introduced a quality filtering and rephrasing step, which increased the instructional quality of the data, improved performance during the annealing phase, and reduced overall compute requirements. Thanks to our architectural model and data choices, including prefiltering, our educational-quality filtering and rephrasal to raise the educational-quality, ELMOD is the strongest perfo
