Latxa-Qwen3-VL-2B-Instruct is a Basque-adapted multimodal and multilingual instruct model built on top of Qwen3-VL-2B-Instruct, a powerful vision-language LLM capable of understanding and generating text and processing images. This model has been adapted by the HiTZ Research Center for improved performance on Basque (`mono_eu` variant), Galician and Catalan (`multi` variant) languages and interactive instruction following.

> These models are still under development.
> The released models are preliminary, and might be updated and improve in the future.

The released model contains several versions (revisions):
 - Multilingual (`multi`): in addition to Basque, the model has been also adapted to Galician and Catalan.
 - Basque monolingual (`mono_eu`): the Basque monolingual variant.

You can choose the model version by specifying the revision when loading the model with `revision="multi"`. By default (`main`) the multilingual variant is downloaded.

## Model Details

### Model Description

Latxa Vision models are a family of Vision-Language Models based on Qwen3-VL. The models were adapted to different languages following [Sainz et al. (2025)](https://aclanthology.org/2025.emnlp-main.1484/) adaptation method. The models are released under different language variants: `multi` (it has been adapted to Basque, Galician and Catalan) and `mono_eu` (adapted only to Basque). 

- **Developed by:** HiTZ Research Center & IXA Research group (University of the Basque Country UPV/EHU)
- **Funded by:** Ikergaitu and ALIA projects (Basque and Spanish Government)
- **Model type:** Vision-Language Instruct Model
- **Language(s) (NLP):** Basque, Galician, Catalan, Spanish, English and more.
- **License:** Apache 2.0
- **Finetuned from model:** Qwen3-VL-2B-Instruct

## Getting Started

Use the code below to get started with the model.

```python
from transformers import pipeline

# Load the text and image to text pipeline
pipe = pipeline("image-text-to-text", model="HiTZ/Latxa-Qwen3-VL-2B-Instruct", revision='multi')

# Messages can be of many types
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/cats.png"},
            {"type": "text", "text": "What do we see in this image?"},
        ]
    }
]
output = pipe(messages)
print(output)
```

## Uses

Latxa models are intended to be used with Basque data; for any other language the performance is not guaranteed.
Regarding the `multi` variant, it was additionally adapted for Galician and Catalan.


### Direct Use

Latxa Instruct models are trained to follow instructions or to work as chat assistants. 

### Out-of-Scope Use

The model is not intended for malicious activities, such as harming others or violating human rights. 
Any downstream application must comply with current laws and regulations. 
Irresponsible usage in production environments without proper risk assessment and mitigation is also discouraged. 


## 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 [Latxa Corpus v1.1](https://huggingface.co/datasets/HiTZ/latxa-corpus-v1.1)). Still, the 
model is based on Qwen3-VL models and can potentially carry the same bias, risk and limitations.

### Recommendations

<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

    abstract = "Instructing language models with user intent requires large instruction datasets, which are only available for a limited set of languages. In this paper, we explore alternatives to conventional instruction adaptation pipelines in low-resource scenarios. We assume a realistic scenario for low-resource languages, where only the following are available: corpora in the target language, existing open-weight multilingual base and instructed backbone LLMs, and synthetically generated instructions sampled from the instructed backbone. We present a comprehensive set of experiments for Basque that systematically study different combinations of these components evaluated on benchmarks and human preferences from 1,680 participants. Our conclusions show that target language corpora are essential, with synthetic instructions yielding robust models, and, most importantly, that using as backbone an instruction-tuned model outperforms using a base non-instructed model. Scaling up to Llama 3.1 Instruct 70B as backbone, our model comes near frontier models of much larger sizes for Basque, without using any Basque instructions. We release code, models, instruction datasets, and human preferences to support full reproducibility in future research on low-resource language adaptation."
