| ## Dataset Details |
|
|
| This dataset includes all the data used to fine-tune [**Luth-0.6B-Instruct**](https://huggingface.co/kurakurai/Luth-0.6B-Instruct) and [**Luth-1.7B-Instruct**](https://huggingface.co/kurakurai/Luth-1.7B-Instruct), enhancing their French capabilities on tasks such as instruction following, mathematics, and general knowledge. The models also improved in English thanks to knowledge transfer between the two languages. |
|
|
| It contains ~338M tokens in French. Our data scripts are available on [GitHub](https://github.com/kurakurai/Luth). |
