# 4M: Massively Multimodal Masked Modeling

*David Mizrahi\*, Roman Bachmann\*, Oguzhan Fatih Kar, Teresa Yeo, Mingfei Gao, Afshin Dehghan, Amir Zamir*

Official implementation and pre-trained models for "4M: Massively Multimodal Masked Modeling" (NeurIPS 2023).

[`Website`](https://4m.epfl.ch) | [`Paper`](https://arxiv.org/abs/2312.06647) | [`GitHub`](https://github.com/apple/ml-4m)

4M is a framework for training "any-to-any" foundation models, using tokenization and masking to scale to many diverse modalities. 
Models trained using 4M can perform a wide range of vision tasks, transfer well to unseen tasks and modalities, and are flexible and steerable multimodal generative models.


## Installation
For install instructions, please see https://github.com/apple/ml-4m. 


## Usage

The RGB tokenizer can be loaded from Hugging Face Hub as follows:
```python
from fourm.vq.vqvae import DiVAE
tok_rgb = DiVAE.from_pretrained('EPFL-VILAB/4M_tokenizers_rgb_16k_224-448')
```

Please see https://github.com/apple/ml-4m/README_TOKENIZATION.md for more detailed instructions and https://github.com/apple/ml-4m for other tokenizer and 4M model checkpoints.
