# ProGen2 Base BF16 MLX Conversion
This repository contains a BF16 MLX-LM conversion of
[`hugohrban/progen2-base`](https://huggingface.co/hugohrban/progen2-base), a
mirror of the base ProGen2 model by Nijkamp et al.
The source checkpoint was downloaded from Hugging Face revision
`71228cbfca5960f9fab5775f378bba3673af9f00` and converted from FP32 to BF16
safetensors. The converted tensor file contains 764,803,616 BF16 parameters.
This conversion was prepared for the standalone replication artifact for
*Many Next Token Predictors are In-context Learners*.
## Files
- `model.safetensors`: BF16 converted ProGen2-base weights.
- `progen2_mlx.py`: MLX-LM custom model implementation.
- `config.json`, tokenizer files, and ProGen custom-code files copied from the
source model with the MLX model-file entry added.
## Loading with MLX-LM
```python
from mlx_lm import load
model, tokenizer = load("N8Programs/ProGen2-base-bf16")
```
