## Intended Uses

This model can be used for:

- **Instruction following** in Valencian, Spanish, and English
- **Intellectual property domain** applications
- **Chat and conversational applications** requiring multilingual support
- **Text generation** with task-specific prompting

## How to Use

### Transformers

```python
import torch
from transformers import pipeline, AutoTokenizer

model_id = "gplsi/Aitana-2B-S-IP-Instruct-IP"
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 = "Explica què és la propietat intel·lectual i quins drets atorga."
result = generator(text, do_sample=True, top_k=10, max_new_tokens=100)
print(result[0]['generated_text'])
# Spanish example
text = "Describe los principales tipos de propiedad intelectual y su marco legal."
result = generator(text, do_sample=True, top_k=10, max_new_tokens=100)
print(result[0]['generated_text'])
# English example
text = "Explain the concept of intellectual property and its importance in innovation."
result = generator(text, do_sample=True, top_k=10, max_new_tokens=100)
print(result[0]['generated_text'])
```

## Evaluation

In the following tables, we present the results obtained with different benchmarks from [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness) in comparison with [Salamandra-2B-Instruct](https://huggingface.co/BSC-LT/Salamandra-2B-Instruct).
