# mmBERT-base-fin-32768
This model is a **55.86% smaller** version of [jhu-clsp/mmBERT-base](https://huggingface.co/jhu-clsp/mmBERT-base) optimized for **Finnish** language via vocabulary size reduction using the [trimming](https://huggingface.co/blog/lbourdois/introduction-to-trimming) method.  
This trimmed model should perform similarly to the original model with only 32,768 tokens and a much smaller memory footprint. However, it may not perform well for other languages as tokens not commonly used in the selected languages were removed from the vocabulary.

## Model Statistics
| Metric | Original | Trimmed | Reduction |
|--------|----------|---------|-----------|
| **Vocabulary size** | 256,000 tokens | 32,768 tokens | **87.20%** |
| **Model size** | 306,939,648 params | 135,497,472 params | **55.86%** |
