# DeSTA2.5-Audio

[📑 Paper](https://arxiv.org/abs/2507.02768) | [👩‍💻 Github](https://github.com/kehanlu/DeSTA2.5-Audio) | [🤗 Model](https://huggingface.co/collections/DeSTA-ntu/desta25-audio-686a6b9e71afd92e1dd87486) | [🤗 Dataset](https://huggingface.co/datasets/DeSTA-ntu/DeSTA-AQA5M-FROM-Llama3.1-8B-Instruct)

**DeSTA2.5-Audio: Toward General-Purpose Large Audio Language Model with Self-Generated Cross-Modal Alignment**
> **Self-generated data is what you need for developing general-purpose LALMs!**

- 🧪 **A new training framework** ([read the paper](https://arxiv.org/abs/2507.02768))  
  - Highly scalable and efficient without task-specific instruction-tuning data  
  - Preserves language ability and avoids catastrophic forgetting  
  - Comprehensive studies on data quality in LALM development  
- 📦 **Open resources for the community**  
  - Model checkpoints and Training scripts
  - DeSTA-AQA5M dataset (5M audio-text pairs from 7,000 hours of audio)  


## 🚀Quickstart

### Installation
```shell
git clone https://github.com/kehanlu/DeSTA2.5-Audio.git
cd DeSTA2.5-Audio
pip install -e .
```

### Inference
```python
from desta import DeSTA25AudioModel

# Load the model from Hugging Face
model = DeSTA25AudioModel.from_pretrained("DeSTA-ntu/DeSTA2.5-Audio-Llama-3.1-8B")
model.to("cuda")

# Run inference with audio input
messages = [
    {
        "role": "system",
        "content": "Focus on the audio clips and instructions."
    },
    {
        "role": "user",
        "content": "<|AUDIO|>\nDescribe this audio.",
        "audios": [{
            "audio": "/path/to/audio.wav",  # Path to your audio file
            "text": None
        }]
    }
]

outputs = model.generate(
    messages=messages,
    do_sample=False,
    top_p=1.0,
    temperature=1.0,
    max_new_tokens=512
)

print(outputs.text)
```
