# Typhoon-Audio Preview

**llama-3-typhoon-v1.5-8b-audio-preview** is a 🇹🇭 Thai *audio-language* model. It supports both text and audio input modalities natively while the output is text. This version (August 2024) is our first audio-language model as a part of our multimodal effort, and it is a research *preview* version. The base language model is our [llama-3-typhoon-v1.5-8b-instruct](https://huggingface.co/scb10x/llama-3-typhoon-v1.5-8b-instruct). 

More details can be found in our [release blog](https://blog.opentyphoon.ai/typhoon-audio-preview-release-6fbb3f938287) and [technical report](). *To acknowledge Meta's effort in creating the foundation model and to comply with the license, we explicitly include "llama-3" in the model name.

## Model Description

- **Model type**: The LLM is based on Typhoon-1.5-8b-instruct, and the audio encoder is based on Whisper's encoder and BEATs.
- **Requirement**: transformers 4.38.0 or newer.
- **Primary Language(s)**: Thai 🇹🇭 and English 🇬🇧
- **Demo**: https://audio.opentyphoon.ai/
- **License**: [Llama 3 Community License](https://llama.meta.com/llama3/license/)

## Usage Example

```python
from transformers import AutoModel

# Initialize from the trained model
model = AutoModel.from_pretrained(
    "scb10x/llama-3-typhoon-v1.5-8b-audio-preview", 
    torch_dtype=torch.float16,
    trust_remote_code=True
)
model.to("cuda")
model.eval()

# Run generation
prompt_pattern="<|begin_of_text|><|start_header_id|>user<|end_header_id|>\n\n<Speech><SpeechHere></Speech> {}<|eot_id|><|start_header_id|>assistant<|end_header_id|>\n\n"
response = model.generate(
    wav_path="path_to_your_audio.wav",
    prompt="transcribe this audio",
    prompt_pattern=prompt_pattern,
    do_sample=False,
    max_length=1200,
    repetition_penalty=1.1,
    num_beams=1,
    # temperature=0.4,
    # top_p=0.9,
    # streamer=streamer # supports TextIteratorStreamer
)
print(response)
```
**Generation Parameters**:
- wav_path (`str`) -- Path to the audio file (format = wav, flac, mp3, etc as long as `soundfile.read` supports)
- prompt (`str`) -- Text input to the model
- prompt_pattern (`str`) -- Chat template that is augmented with special tokens, and it must be set the same as one during training
- max_length (`int`, *optional*, defaults to 150)
- num_beams (`int`, *optional*, defaults to 4)
- do_sample (`bool`, *optional*, defaults to True)
- min_length (`int`, *optional*, defaults to 1)
- top_p (`float`, *optional*, defaults to 0.9)
- repetition_penalty (`float`, *optional*, defaults to 1.0),
- length_penalty (`float`, *optional*, defaults to 1.0),
- temperature (`float`, *optional*, defaults to 1.0),
- streamer (`TextIteratorStreamer`, *optional*, defaults to `None`) -- this allows streaming output

## Intended Uses & Limitations
This model is experimental and may not always follow human instructions accurately, making it prone to generating hallucinations. Additionally, the model lacks moderation mechanisms and may produce harmful or inappropriate responses. Developers should carefully assess potential risks based on their specific applications.
