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. 
We are releasing code and models for "4M: Massively Multimodal Masked Modeling" (here denoted 4M-7), as well as "4M-21: An Any-to-Any Vision Model for Tens of Tasks and Modalities" (here denoted 4M-21).


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


## Usage

This model can be loaded from Hugging Face Hub as follows:
```python
from fourm.models.fm import FM
fm = FM.from_pretrained('EPFL-VILAB/4M-7-T2I_XL_CC12M')
```

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