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.

More details can be found in our 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

Usage Example

from transformers import AutoModel
import soundfile as sf
import librosa

# 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()

# read a wav file (it needs to be in 16 kHz and clipped to 30 seconds)
audio, sr = sf.read("path_to_your_audio.wav")
if len(audio.shape) == 2:
    audio = audio[:, 0]
if len(audio) > 30 * sr:
    audio = audio[: 30 * sr]
if sr != 16000:
    audio = librosa.resample(audio, orig_sr=sr, target_sr=16000, res_type="fft")

# 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(
    audio=audio,
    prompt="transcribe this audio",
    prompt_pattern=prompt_pattern,
    do_sample=False,
    max_new_tokens=512,
    repetition_penalty=1.1,
    num_beams=1,
    # temperature=0.4,
    # top_p=0.9,
)
print(response)

Generation Parameters:

• audio -- audio input, e.g., using soundfile.read or librosa.resample to read a wav file like the example above
• 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_new_tokens (int, optional, defaults to 1024)
• num_beams (int, optional, defaults to 4)
• do_sample (bool, optional, defaults to True)
• 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),

This is also model.generate_stream() for streaming generation. Please refer to modeling_typhoonaudio.py for this function.

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.
