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)
  • 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

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

Inference

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)
