NorMistral-11b-warm is a large Norwegian language model initialized from [Mistral-Nemo-Base-2407](https://huggingface.co/mistralai/Mistral-Nemo-Base-2407) and 
continuously pretrained on a total of 260 billion subword tokens -- using a mix of Scandinavian, Sámi, English and code data (four repetitions of open Norwegian texts).

*Disclaimer: This model is pretrained on raw (mostly web-based) textual data. It is not finetuned to follow instructions, and it can generate harmful completions after inappropriate user prompts. It is primarily intended for research purposes.*

## Tokenizer

This model uses a new tokenizer, specially trained on the target languages. Therefore it offers substantially faster inference than the original Mistral-Nemo-Base-2407 model. Here are the subword-to-word split ratios across different languages:

| Tokenizer  | # tokens | Bokmål | Nynorsk | Sámi  | Danish | Swedish |
|------------|--------|--------|---------|-------|--------|---------|
| Mistral-Nemo-Base-2407    | 131072 | 1.79   | 1.87    | 2.63  | 1.82   | 2.00    |
| NorMistral-11b-warm | 51200 | 1.22   | 1.28    | 1.82  | 1.33   | 1.39    |
