| ## Quickstart |
| **Release 2.0** (February 7, 2022) |
|
|
| Please check also our newer models: [NorBERT 3 family](https://huggingface.co/ltg/norbert3-base), trained with a better architecture. |
|
|
| Trained on the very large corpus of Norwegian (C4 + NCC, about 15 billion word tokens). |
| Features a 50 000 words vocabulary and was trained using Whole Word Masking. |
|

|
|
| NorBERT was trained as a part of NorLM, a joint initiative of the projects [EOSC-Nordic](https://www.eosc-nordic.eu/) (European Open Science Cloud), |
| coordinated by the [Language Technology Group](https://www.mn.uio.no/ifi/english/research/groups/ltg/) (LTG) at the University of Oslo. |
|
|
| The computations were performed on resources provided by UNINETT Sigma2 - the National Infrastructure for High Performance Computing and Data Storage in Norway. |
|
|
| ## NorBERT-3 |
| In 2023, we released a new family of *NorBERT-3* language models for Norwegian. In general, we now recommend using these models: |
|
|
| - [NorBERT 3 xs](https://huggingface.co/ltg/norbert3-xs) (15M parameters) |
| - [NorBERT 3 small](https://huggingface.co/ltg/norbert3-small) (40M parameters) |
| - [NorBERT 3 base](https://huggingface.co/ltg/norbert3-base) (123M parameters) |
| - [NorBERT 3 large](https://huggingface.co/ltg/norbert3-large) (323M parameters) |
|
|
| NorBERT-3 is described in detail in this paper: |
| [NorBench – A Benchmark for Norwegian Language Models](https://aclanthology.org/2023.nodalida-1.61/) (Samuel et al., NoDaLiDa 2023) |
