+* Running large language models on local Apple Silicon hardware (M1, M2, M3) ARM with unified CPU/GPU memory)
+
+
+### 1. Install MLX on MacOS
+#### Mac MX series only
+MLX supports GPU acceleration on Apple Metal backend via `mlx-lm` Python package. Follow Instructions at [Install `mlx-lm` package](https://github.com/ml-explore/mlx-examples/tree/main/llms)
+
+
+### 2. Load Models with MLX
+MLX supports common HuggingFace models directly, but it's recommended to use converted and tested quantized models (depending on your hardware capability) provided by the [mlx-community](https://huggingface.co/mlx-community).
+
+Follow Instructions at [Install `mlx-lm` package](https://github.com/ml-explore/mlx-examples/tree/main/llms)
+
+1. Browse the available models  [HuggingFace](https://huggingface.co/models?search=mlx-community)
+2. Copy the text from the model page `<author>/<model_id>` (ex: `mlx-community/Meta-Llama-3-8B-Instruct-4bit`)
+3. Check model size. Models that can run in CPU/GPU unified memory perform the best.
+4. Follow the instructions to launch the model server [Run OpenAI Compatible Server Locally](https://github.com/ml-explore/mlx-examples/blob/main/llms/mlx_lm/SERVER.md)
+
+```mlx_lm.server --model <author>/<model_id>```
+
+### 3. Configure LibreChat
+Use `librechat.yaml` [Configuration file (guide here)](./ai_endpoints.md) to add MLX as a separate endpoint, an example with Llama-3 is provided.
