+# NeuralTxt Reward Model MLX
+
+MLX-ready package for [`paperbd/neuraltxt-reward-tiny`](https://huggingface.co/paperbd/neuraltxt-reward-tiny).
+
+This repo contains:
+
+- `model.safetensors`: MiniLM/BERT encoder weights readable by MLX.
+- `reward_head.safetensors`: clamped linear reward head in MLX safetensors format.
+- tokenizer files copied from the source reward model.
+
+## Usage
+
+```python
+from neuraltxt import NeuralTxtReward
+
+reward = NeuralTxtReward(backend="mlx")
+score = reward.score(
+    response="Paris is the capital of France.",
+    reference="The capital of France is Paris.",
+)
+```
+
+To load this repo explicitly:
+
+```python
+reward = NeuralTxtReward("paperbd/neuraltxt-reward-tiny-mlx", backend="mlx")
+```
