# mlx-llm
Large Language Models (LLMs) applications and tools running on Apple Silicon in real-time with [Apple MLX](https://github.com/ml-explore/mlx).
Go to the entire [Youtube Video](https://www.youtube.com/watch?v=vB7tk6W6VIw).
## **How to install 🔨**
```
pip install mlx-llm
```
## **Models 🧠**
Currently, out-of-the-box supported models are:
| Family | Models |
|---------------------|----------------|
| LLaMA 2 | llama_2_7b_chat_hf, llama_2_7b_hf |
| LLaMA 3 | deepseek_r1_distill_llama_8b, llama_3_8b, llama_3_8b_instruct, hermes_2_pro_llama_3_8b, llama_3_2_1b_instruct, llama_3_2_3b_instruct |
| Phi3 | phi_3_mini_4k_instruct, phi_3_mini_128k_instruct, phi_3.5_mini_instruct |
| Mistral | mistral_7b_instruct_v0.2, openhermes_2.5_mistral_7b, starling_lm_7b_beta |
| TinyLLaMA | tiny_llama_1.1B_chat_v1.0 |
| Gemma | gemma_1.1_2b_it, gemma_1.1_7b_it, gemma_2_2b_it, gemma_2_9b_it |
| OpenELM | openelm_270M_instruct, openelm_450M_instruct, openelm_1.1B_instruct, openelm_3B_instruct |
| SmolLM2 | smollm2_1.7B_instruct, smollm2_360M_instruct, smollm2_135M_instruct |
To create a model with pre-trained weights from HuggingFace:
```python
from mlx_llm.model import create_model
# loading weights from HuggingFace
model = create_model("deepseek_r1_distill_llama_8b")
```
You can also load a new version of pre-trained weights for a specific model directly from HuggingFace:
- set `weights` by adding `hf://` before the HuggingFace repository
- if necessary, specify custom model configs (rope_theta, rope_traditional, vocab_size, norm_eps)
Here's an example of how to to it:
```python
from mlx_llm.model import create_model
# an example of loading new weights from HuggingFace
model = create_model(
model_name="openelm_1.1B_instruct", # it's the base model
weights="hf://apple/OpenELM-1.1B", # new weights from HuggingFace
)
# an example of loading new weights from HuggingFace with custom model configs
model = create_model(
model_name="llama_3_8b_instruct", # it's the base model
weights="hf://gradientai/Llama-3-8B-Instruct-262k", # new weights from HuggingFace
model_config={
"rope_theta": 207112184.0
}
)
```
### **Quantization 📉**
To quantize a model and save its weights just use:
```python
from mlx_llm.model import create_model, quantize, get_weights
from mlx_llm.utils.weights import save_weights
# create the model from original weights
model = create_model("llama_3_8b_instruct")
# quantize the model
model = quantize(model, group_size=64, bits=4)
# getting weights dict (similar to state_dict in PyTorch)
weights = get_weights(model)
# save the model
save_weights(weights, "llama_3_8b_instruct-4bit.safetensors")
```
### **Model Embeddings ✴️**
Models in `mlx-llm` are able to extract embeddings from a given text.
```python
import mlx.core as mx
from mlx_llm.model import create_model, create_tokenizer
model = create_model("llama_3_8b_instruct")
tokenizer = create_tokenizer('llama_3_8b_instruct')
text = ["I like to play basketball", "I like to play tennis"]
tokens = tokenizer(text)
x = mx.array(tokens["input_ids"])
embeds, _ = model.embed(x, norm=True)
```
### **Chat with LLM 📱**
`mlx-llm` comes with tools to easily run your LLM chat on Apple Silicon.
To chat with an LLM provide:
- a system prompt --> to set the overall tone of the LLM
- optional previous interactions to set the mood of the conversation
```python
from mlx_llm.chat import ChatSetup, LLMChat
model_name = "tiny_llama_1.1B_chat_v1.0"
chat = LLMChat(
model_name=model_name,
chat_setup=ChatSetup(
system="You are Michael Scott from The Office. Your goal is to answer like him, so be funny and inappropriate, but be brief.",
history=[
{"question": "What is your name?", "answer": "Michael Scott"},
