🐂 domestic-yak, a Macedonian LM (base version)
Model Summary
This model is a Macedonian language adaptation of the Llama 3.1 8B model. It has undergone continued pretraining on a deduplicated version of the Macedonian Corpus Raw dataset, containing approximately 1.6 billion tokens. The model has been pretrained for one epoch on this corpus, making it well-suited for tasks involving the Macedonian language, such as text classification, language generation, and translation.
📊 Results
The table below compares the performance of our model, domestic-yak-8B, with its foundational model, Llama 3.1-8B Instruct evaluated using the macedonian-llm-eval benchmark.
As shown in the table, domestic-yak-8B consistently outperforms its foundational model on all tasks.

| WinoGrande | 0.6259 ± 0.0136 | 0.5683 ± 0.0139 |
Quantitative evaluation is just one part of the story. We also conducted qualitative tests, interacting with the model to assess its ability to generate coherent and relevant responses in Macedonian. The results were satisfying: the model not only mastered the language's grammar but also demonstrated a natural and fluent style.

⚠️ Limitations
- Biases: The model may show biases present in the training dataset. Efforts were made to clean and deduplicate the corpus, but further bias mitigation might be necessary for sensitive applications.
- Domain Specificity: While the dataset covers diverse domains, performance may vary for niche or underrepresented topics. For example, the dataset is heavily skewed toward 'news'-themed texts, while domains such as 'science' or 'medicine' are less represented.
- Chat Capabilities: This version is the base model so its chat capabilities might be limited. If you would like to chat use the instruct version.
