# MatMul-Free LL

<!-- Provide a quick summary of what the model is/does. -->

## Model Details

[[Paper](https://arxiv.org/abs/2406.02528)] [[Code](https://github.com/ridgerchu/matmulfreellm/tree/master)]

MatMul-Free LM is a language model architecture that eliminates the need for Matrix Multiplication (MatMul) operations. 
This repository provides an implementation of MatMul-Free LM that is compatible with the 🤗 Transformers library.

## Scaling Law

We evaluate how the scaling law fits to the 370M, 1.3B and 2.7B parameter models in both Transformer++ and our model. 
For a fair comparison, each operation is treated identically, though our model uses more efficient ternary weights in some layers. 
Interestingly, the scaling projection for our model exhibits a steeper descent compared to Transformer++, 
suggesting our architecture is more efficient in leveraging additional compute to improve performance.

## Usage

We provide the implementations of models that are compatible with 🤗 Transformers library. 
Here's an example of how to initialize a model from the default configs in ```matmulfreelm```: 
This is a huggingface-compatible library that you can use such command to initialize the model with huggingface ```AutoModel```:

```shell
pip install transformers
pip install -U git+https://github.com/ridgerchu/matmulfreellm
```

```python
from mmfreelm.models import HGRNBitConfig
from mmfreelm.layers import hgrn_bit

from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("ridger/MMfreeLM-2.7B")
```
