We introduce Latxa, a family of large language models for Basque ranging from 7 to 70 billion parameters. Latxa is based on Llama 2, which we continue pretraining on a new Basque corpus comprising 4.3M documents and 4.2B tokens. Addressing the scarcity of high-quality benchmarks for Basque, we further introduce 4 multiple choice evaluation datasets: EusProficiency, comprising 5,169 questions from official language proficiency exams; EusReading, comprising 352 reading comprehension questions; EusTrivia, comprising 1,715 trivia questions from 5 knowledge areas; and EusExams, comprising 16,046 questions from public examinations. In our extensive evaluation, Latxa outperforms all previous open models we compare to by a large margin. In addition, it is competitive with GPT-4 Turbo in language proficiency and understanding, despite lagging behind in reading comprehension and knowledge-intensive tasks. Both the Latxa family of models, as well as our new pretraining corpora and evaluation datasets, are publicly available under open licenses. Our suite enables reproducible research on methods to build LLMs for low-resource languages.

Use the code below to get started with the model.
from transformers import pipeline
pipe = pipeline("text-generation", model="HiTZ/latxa-7b-v1.1")
text = "Euskara adimen artifizialera iritsi da!"
pipe(text, max_new_tokens=50, num_beams=5)

]Code for training models on the CINECA HPC Leonardo cluster using GPT-Neox. If you train on another cluster you will need to update some settings. Check the GPT-Neox documentation if you have any doubts.
The training process is divided into several steps: loading the required modules, creating a virtual environment, installing GPT-Neox, downloading the Llama models, converting the checkpoints, downloading the data, preprocessing the data, defining the training configs, setting up wandb, running the training, and converting the Neox checkpoints to HF.
Install modules needed for GPT-Neox. You can add this to .bashrc so that modules are loaded automatically:
module load profile/deeplrn
module load python/3.10.8--gcc--11.3.0
module load cuda/11.8
module load openmpi/4.1.4--gcc--11.3.0-cuda-11.8
module load zlib/1.2.13--gcc--11.3.0
module load git-lfsCreate a virtual environment:
python -m venv $WORK/environments/neox-envActivate the virtual environment. You can add this to .bashrc so that the virtual environment is activated automatically:
source $WORK/environments/neox-env/bin/activateClone the repository and install the requirements:
git clone https://github.com/EleutherAI/gpt-neox
cd gpt-neoxInstall the requirements:
pip install -r requirements/requirements.txt
pip install -r requirements/requirements-wandb.txt
pip install -r requirements/requirements-flashattention.txt
python ./megatron/fused_kernels/setup.py install # optional, if using fused kernelsAs the Leonardo cluster does not have internet connection, offline mode must be used. Change default wandb config directory:
export WANDB_CONFIG_DIR=$HOME/.wandbLogin to wandb:
wandb loginChange wandb to offline mode:
wandb offlineLogs will be saved to $WORK/gpt-neox/wandb directory.
To sync logs to wandb, run:
wandb sync $WORK/gpt-neox/wandbDownload the raw Llama models from the following links:
Llama-2-7b: https://huggingface.co/meta-llama/Llama-2-7b
Llama-2-13b: https://huggingface.co/meta-llama/Llama-2-13b
Llama-2-70b: https://huggingface.co/meta-llama/Llama-2-70b
Convert the raw Llama models to Neox format using scripts in convert directory.
cd convert
bash convert_raw_llama_weights_to_neox_7b.sh
bash convert_raw_llama_weights_to_neox_13b.sh
bash convert_raw_llama_weights_to_neox_70b.shDownload the pretraining data from the following links:
Euscrawl: https://huggingface.co/datasets/HiTZ/euscrawl
Pile: https://huggingface.co/datasets/EleutherAI/pile
Latxa v1.1: https://huggingface.co/datasets/HiTZ/latxa-corpus-v1.1
Preprocess data using scripts available in preprocess directory:
To preprocess the Pile dataset, run bash preprocess_data_pile.sh.
To preprocess the Latxa v1 dataset, run bash preprocess_data_latxa-v1.sh.
To preprocess the Latxa v1.1 dataset, run bash preprocess_data_latxa-v1.1.sh.
Define training configs in the configs directory. You can use the existing configs as a template. There are two base configs which are common to all models, and include details such as checkpointing and logging. The first one is used for 7B and 13B models, and the other one for 70B models. Additional configs are divided into 4 folders, depending on the type of parameters: data, deepspeed, hyperparameters and models.
data: contains the data configuration files for Latxa v1 and v1.1.deepspeed: contains the deepspeed configuration file for Zero 1.hyperparameters: contains the hyperparameters configuration files for Latxa v1 and v1.1 of three sizes.models: contains the model configuration files for three sizes.
Run training using scripts available in train directory. There are scripts for Latxa v1 and v1.1 models of three sizes. For example, to train Latxa 7B v1.1, run:
cd train/latxa-7b
bash llama-2-7b-v1.1.shThe Neox checkpoints can be converted to HF using the convert_neox_to_hf.py script. The script take an input path, the output path, the model config, the precision and the architecture as arguments. You can find example scripts in the convert directory. For example, to convert the Latxa 7B v1.1 model, run:
cd convert
bash convert_neox_to_hf_7b_v1.1.shEvaluation scripts for open models are in the scripts directory. openai directory contains scripts for evaluating openai models. Evaluation results are in the results directory.
You will need to install LM Evaluation Harness. Clone the repository and install the requirements:
git clone https://github.com/EleutherAI/lm-evaluation-harness
cd lm-evaluation-harness
pip install -e .To run evaluation on open models, use the scripts in the scripts directory. Each script evaluates a model in all the tasks. For example, to run evaluation on Latxa v1.1 7b, run:
sbatch lm_eval_latxa-7b-v1.1.slurmEvaluation results are in the results directory. Each model has a directory with the results of the evaluation in each task. The results are in the form of a json file with the average scores of the model in each task.
To run evaluation on OpenAI models, use the scripts in the openai directory. There is a python script to evaluate each dataset, and a bash script for each model and dataset. For example, to run evaluation on GPT-3.5 Turbo on EusTrivia, run:
bash gpt-3.5-turbo-0125_eus_trivia.shEvaluation results are in the results directory. Each model has a directory with the results of the evaluation in each task. In this case, all the outputs of the models are saved for each task. Scores can be calculated using the correct field. For EusTrivia and EusExams, there are additional scripts to obtained detailed results by category. For example, to get detailed results for GPT-3.5 Turbo on EusTrivia, run:
python calculate_accuracy_eus_trivia.pyWe keep updating and improving our base model, this section covers the major releases and changes we made. We recommend users always to use the latest version available.
- v1.2-latest: (bug-fix in v1.1) Avoids generating JSON-like responses.
- v1.1: (improvement) The model is trained with much more corpora. Please take a look at the ACL paper for more details.
- v1.0: Initial version.
