# CodeFormulaV2-mlx-q8
8-bit quantized MLX conversion of [docling-project/CodeFormulaV2](https://huggingface.co/docling-project/CodeFormulaV2), produced with `mlx_vlm.convert --quantize --q-bits 8`. The text decoder linear layers are quantized to 8 bits per weight; the vision encoder stays at bf16 (the mlx-vlm convention via `skip_multimodal_module`).
Architecture, training data, and intended use are described on the upstream model page. This repo only re-encodes the weights at lower precision; no retraining or modification of behaviour was performed.
A bf16 variant is also available: [`mlx-community/CodeFormulaV2-mlx-bf16`](https://huggingface.co/mlx-community/CodeFormulaV2-mlx-bf16).
## Usage
```bash
pip install mlx-vlm
```
```python
from mlx_vlm import load, generate
from mlx_vlm.prompt_utils import apply_chat_template
model, processor = load("mlx-community/CodeFormulaV2-mlx-q8")
prompt = apply_chat_template(processor, model.config, "<formula>", num_images=1)
result = generate(
model, processor,
prompt=prompt,
image="path/to/image.png",
temperature=0.0,
)
print(result.text)
```
Use `"<formula>"` as the prompt for a math-expression image, `"<code>"` for a code-block image, per the upstream model card.
