+As opposed to [mlx-community/CodeLlama-7b-Instruct-hf-4bit-MLX](https://huggingface.co/mlx-community/CodeLlama-7b-Instruct-hf-4bit-MLX), this
+one is converted from the base model using a newer MLX-LM version which uses newer and improved quantization and generates model
+in a more standard format. For context see [Issue#130](https://github.com/ml-explore/mlx-lm/issues/130) and [PR#114](https://github.com/ml-explore/mlx-lm/pull/114)
