Merged summary

TL;DR - ELMOD is a German-first 2.7B-parameter language model optimized for mobile and resource-constrained inference. It reportedly leads German models below 3B parameters and matches some 7B-model performance.

  • Trained exclusively on public data using 55,000 H100 GPU hours.
  • Uses German-specific preprocessing for morphology, compound words, and orthographic conventions.
  • Quality filtering and rephrasing improved instructional data quality and annealing performance while reducing compute needs.
  • Its compact architecture targets efficient on-device deployment.
