Aitana-2B-S-tourism-Instruct

Aitana-2B-S-tourism-Instruct is an instruction-tuned generative language model from the Aitana family, developed by the GPLSI (Language and Information Systems Group) at the University of Alicante. Built on gplsi/Aitana-2B-S-tourism-base, this model has been fine-tuned to follow instructions across Valencian, Spanish, and English, with specialized capabilities for tourism domain applications.

Model Description

Aitana-2B-S-tourism-Instruct extends the Aitana-2B-S-tourism-base domain-specific foundation model with instruction fine-tuning. This combination makes it particularly well-suited for tourism-related tasks requiring instruction following in Valencian, Spanish, and English.

Training Data

This model was instruction fine-tuned using the following data:

Intended Uses

This model can be used for:

• —Tourism text generation in Valencian, Spanish, and English
• —Travel content creation and visitor assistance
• —Instruction following with tourism domain expertise
• —Fine-tuning for specific tourism downstream tasks

Note: This model combines tourism domain specialization with instruction-following capabilities. For general-purpose instruction following, consider other models in the Aitana family.

How to Use

Transformers

import torch
from transformers import pipeline, AutoTokenizer

model_id = "gplsi/Aitana-2B-S-tourism-Instruct"
tokenizer = AutoTokenizer.from_pretrained(model_id)
generator = pipeline(
    "text-generation",
    model=model_id,
    tokenizer=tokenizer,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)
# Valencian example
text = "Recomana'm les millors platges de la Costa Blanca per a unes vacances familiars."
result = generator(text, do_sample=True, top_k=10, max_new_tokens=100)
print(result[0]['generated_text'])
# Spanish example
text = "Describe los principales atractivos turísticos de la Comunidad Valenciana."
result = generator(text, do_sample=True, top_k=10, max_new_tokens=100)
print(result[0]['generated_text'])
# English example
text = "What are the best cultural sites to visit in Valencia?"
result = generator(text, do_sample=True, top_k=10, max_new_tokens=100)
print(result[0]['generated_text'])
