+
+The Model [mlx-community/Codestral-22B-v0.1-4bit](https://huggingface.co/mlx-community/Codestral-22B-v0.1-4bit) was converted to MLX format from [bullerwins/Codestral-22B-v0.1-hf](https://huggingface.co/bullerwins/Codestral-22B-v0.1-hf) using mlx-lm version **0.14.0**.
+
+## Use with mlx
+
+```bash
+pip install mlx-lm
+```
+
+```python
+from mlx_lm import load, generate
+
+model, tokenizer = load("mlx-community/Codestral-22B-v0.1-4bit")
+response = generate(model, tokenizer, prompt="hello", verbose=True)
+```
