+# **Model Card for Latxa 7b**
+
+![Latxa](latxa.jpeg)
+
+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 7b 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-2-7b
+* **Contact:** [email protected] 
+
+
+## **Getting started**
+
+Use the code below to get started with the model.
+
+```python
+
+from transformers import pipeline
+
+pipe = pipeline("text-generation", model=”HiTZ/latxa-7b-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.
