ONE-PEACE is a general representation model across vision, audio, and language modalities, Without using any vision or language pretrained model for initialization, ONE-PEACE achieves leading results in vision, audio, audio-language, and vision-language tasks. Furthermore, ONE-PEACE possesses a strong emergent zero-shot retrieval capability, enabling it to align modalities that are not paired in the training data.

Below shows the architecture and pretraining tasks of ONE-PEACE. With the scaling-friendly architecture and modality-agnostic tasks, ONE-PEACE has the potential to expand to unlimited modalities.

Online Demo

We provide the online demo in Huggingface Spaces. In this demo, you can combine multiple modalities to retrieve related images, such as audio-to-image, audio+text-to-image, audio+image-to-image, and even audio+image+text-to-image.

Models and Results

Model Card

We list the parameters and pretrained checkpoints of ONE-PEACE below. Note that ONE-PEACE can be disassembled into different branches to handle different tasks. We also provide the vision-branch of ONE-PEACE, which can be used to perform vision tasks.

Usage

API

We provide a simple code snippet to show how to use the API for ONE-PEACE. We use ONE-PEACE to compute embeddings for text, images, and audio, as well as their similarities:

import torch
from one_peace.models import from_pretrained

device = "cuda" if torch.cuda.is_available() else "cpu"
# "ONE-PEACE" can also be replaced with ckpt path
model = from_pretrained("ONE-PEACE", device=device, dtype="float32")

# process raw data
src_tokens = model.process_text(["cow", "dog", "elephant"])
src_images = model.process_image(["demo_assets/dog.JPEG", "demo_assets/elephant.JPEG"])
src_audios, audio_padding_masks = model.process_audio(["demo_assets/cow.flac", "demo_assets/dog.flac"])

with torch.no_grad():
    # extract normalized features
    text_features = model.extract_text_features(src_tokens)
    image_features = model.extract_image_features(src_images)
    audio_features = model.extract_audio_features(src_audios, audio_padding_masks)

    # compute similarity
    i2t_similarity = image_features @ text_features.T
    a2t_similarity = audio_features @ text_features.T

print("Image-to-text similarities:", i2t_similarity)
print("Audio-to-text similarities:", a2t_similarity)

Training & Inference

If you are not satisfied with only using the API, we offer comprehensive training and inference instructions for audio & multimodal and vision tasks.
