tokenizer = AutoTokenizer.from_pretrained("HiTZ/eu_Qwen3-14B-Base")
model = AutoModelForCausalLM.from_pretrained("HiTZ/eu_Qwen3-14B-Base", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,

HiTZ/eu_Qwen3-14B-Base

This is a Basque (eu) language-specific base language model trained by the HiTZ Research Center, starting from Qwen3-14B-Base and further pretrained on curated Basque data.

This model is released as a base model, intended for further fine-tuning or adaptation (e.g., instruction tuning, domain adaptation).

Training Data

To train language-specific base LLMs, we followed the methodology proposed by Etxaniz et al. (2024), originally developed for Basque, and extended it to other low-resource languages. To enable fair comparisons across languages, we limited the corpus size for each language to roughly the same number of tokens. We also included a small English subset to mitigate catastrophic forgetting.

Corpus composition

Language	Documents	Tokens (Qwen3)
Basque (eu)	4.2M	~3.5B
English (en)	0.5M	~0.3B

Token counts vary slightly depending on the tokenizer, but remain comparable in overall size.

Data sources

Basque data was obtained from the Latxa corpus, which consists primarily of large-scale web-crawled content, news articles, and encyclopedic text.
The English subset was sampled from the FineWeb corpus.

Model Training

Sequence length: 8,196 tokens
Effective batch size: 256 sequences
Tokens per optimization step: ~2M
Learning rate schedule: cosine decay with 10% warm-up
Peak learning rate: 1e-5

Training was conducted on the CINECA Leonardo high-performance computing cluster using Fully Sharded Data Parallel (FSDP) across 32 nodes, each equipped with 4 NVIDIA A100 GPUs (64 GB).

Getting Started

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "HiTZ/eu_Qwen3-14B-Base"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

inputs = tokenizer("Kaixo!", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=50)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
