Overview

DiscoResearch/Llama3-German-8B is an 8 billion parameter large language model, a specialized version of Meta's Llama3-8B, continuously pretrained on 65 billion high-quality German tokens. This effort, a collaboration between DiscoResearch and Occiglot with support from DFKI and hessian.Ai, addresses Llama3's suboptimal German performance due to its limited multilingual training data.

Key Capabilities

• Enhanced German Performance: Demonstrates strong improvements in German linguistic understanding and general reasoning, particularly on the Hellaswag benchmark, compared to the base Llama3-8B.
• Minimal English Degradation: Achieves German specialization with minimal impact on English performance, despite the absence of replay during training.
• Efficient Training: Utilizes a novel document packing strategy based on "Fewer Truncations Improve Language Modeling" for higher packing efficiency and improved benchmark scores.
• Base Model: Designed as a foundational model, suitable for further fine-tuning to specific German language tasks.

Model Configurations

DiscoResearch offers several configurations:

• Base model (this one) with continued pretraining.
• Long-context version (32k context length).
• Instruction-tuned versions of both base and long-context models.
• Experimental DARE-TIES Merge with Llama3-Instruct.
• Collection of Quantized versions.

Good For

• Developers and researchers requiring a high-performance German-centric large language model.
• Applications demanding strong linguistic understanding and reasoning in German.
• As a base for fine-tuning custom German-specific LLM applications.
