# **Model Card for Latxa 70b**
Latxa is a collection of foundation models specifically tuned for Basque. Based on Meta’s LLaMA 2 model family, these models were further trained with Euscrawl, a highly curated Basque corpora ([Artetxe et al., 2022](https://aclanthology.org/2022.emnlp-main.499/)). Ranging from 7 billion to 70 billion parameters, these models are currently the biggest and best-performing LLMs built for Basque. This is the 70b repository, links to other models can be found in the [Latxa Collection](https://huggingface.co/collections/HiTZ/latxa-65a697e6838b3acc53677304).

# **Model Details**
## **Model Description**
Latxa is a family of Large Language Models (LLM) based on Meta’s [LLaMA models](https://huggingface.co/meta-llama). Current LLMs exhibit incredible performance for high-resource languages such as English, but, in the case of Basque and other low-resource languages, their performance is close to a random guesser. These limitations widen the gap between high- and low-resource languages when it comes to digital development. We present Latxa to overcome these limitations and promote the development of LLM-based technology and research for the Basque language. Latxa models follow the same architecture as their original counterparts and were further trained in Euscrawl v1 ([Artetxe et al., 2022](https://aclanthology.org/2022.emnlp-main.499/)), a high-quality Basque corpora.
The models are released in three sizes: 7B, 13B and 70B.
* **Developed by:** HiTZ Research Center & IXA Research group (University of the Basque Country UPV/EHU)
* **Model type:** Language model
* **Language(s) (NLP):** en, eu
* **License:** llama2
* **Parent Model:** meta-llama/Llama-2-70b
* **Contact:** hitz@ehu.eus
## **Getting started**
Use the code below to get started with the model.
```python
from transformers import pipeline
pipe = pipeline("text-generation", model=”HiTZ/latxa-70b-v1”)
text = "Euskara adimen artifizialera iritsi da!"
pipe(text, max_new_tokens=50, num_beams=5)
>> [
{
'generated_text': 'Euskara adimen artifizialera iritsi da!\nEuskararen eta adimen artifizialaren arteko harremana aspaldikoa da,'
' baina azken urteotan aurrerapauso handiak eman dira arlo horretan'
}
]
```
# **Uses**
Latxa models are intended to be used with Basque data; for any other language the performance is not guaranteed. Same as the original, Latxa inherits the [LLaMA-2 License](https://ai.meta.com/llama/license/) which allows for commercial and research use.
## **Direct Use**
Latxa family models are pre-trained LLMs without any task-specific or instruction fine-tuning. That is, the model can either be prompted to perform a specific task or further fine-tuned for specific use cases.
## **Out-of-Scope Use**
The model was not fine-tuned to follow instructions or to work as a chat assistant, therefore, this kind of usage is not tested nor recommended.
# **Bias, Risks, and Limitations**
In an effort to alleviate the potentially disturbing or harmful content, Latxa has been trained on carefully selected and processed data which comes mainly from local media, national/regional newspapers, encyclopedias and blogs (see Euscrawl below). Still, the model is based on LLaMA models and can potentially carry the same bias, risk and limitations.
Please see the LLaMA’s _Ethical Considerations and Limitations _for further information.
# **Training Details**
## **Training Data**
The models were trained on EusCrawl v1, a high-quality corpus for Basque comprising 1.72M documents, 288M words, totalling 2.1GiB of uncompressed text. EusCrawl was built using ad-hoc scrapers to extract text from 33 Basque websites with high-quality content, resulting in cleaner text compared to general-purpose approaches.
See more details in the [EusCrawl](https://huggingface.co/datasets/HiTZ/euscrawl) dataset card.
Additionally, 100K documents of English data randomly selected from the [Pile](https://huggingface.co/datasets/EleutherAI/pile) dataset were also included to avoid catastrophic forgetting.
## **Training Procedure**
The models were trained using the GPT-Neox library on the HPC CINECA computing cluster. All the models were approximately trained with an effective batch size of 2M tokens for 1000 to 2000 steps.

# **Evaluation**
We evaluated the models on zero-shot and few-shot settings on generative, multiple-choice and classification tasks. We used the basque partitions of each dataset.
## **Testing Data, Factors & Metrics**
### **Testing Data**
* **Belebele** ([Bandarkar et al.](https://arxiv.org/abs/2308.16884)): Belebele is a multiple-choice machine reading comprehension (MRC) dataset spanning 122 language variants. We evaluated the model in a 5-shot fashion.
* Data card: [https://huggingface.co/datasets/facebook/belebele](https://huggingface.co/datasets/facebook/belebele)
* **X-StoryCloze** ([Lin et al.](https://arxiv.org/abs/2112.10668)): XStoryCloze consists of the professionally translated version of the English StoryCloze dataset to 10 non-English languages. Story Cloze is a commonsense reasoning dataset which consists of choosing the correct ending to a four-sentence story. We evaluated the model in a 0-shot fashion.
* Data card: [https://huggingface.co/datasets/juletxara/xstory_cloze](https://huggingface.co/datasets/juletxara/xstory_cloze)
* **BasqueGLUE** ([Urbizu et al.](https://aclanthology.org/2022.lrec-1.172.pdf)): BasqueGLUE is a NLU benchmark for Basque. We evaluated the model in a 5-shot fashion on the following tasks:

* Tasks:
* **BEC2016eu**: Sentiment analysis on tweets about the 2016 Basque elections campaign.
* **VaxxStance**: Stance detection on tweets around the anti-vaccine movement.
* **BTHCv2**: Topic classification of news extracts with 12 categories.
* **EpecKorrefBin**: Correference detection task similar to WSC.
* **QNLIeu**: Q&A NLI built from the Basque Wikipedia.
* **WiCeu**: Basque Word-in-Context task.
### **Metrics**
