pip install mlx-lm

Usage

CLI

# Chat interactively
mlx_lm.chat --model SirSahOl/Jev-Style-0.8B-Decision-v3-mlx-16bit

# Generate text
mlx_lm.generate --model SirSahOl/Jev-Style-0.8B-Decision-v3-mlx-16bit --prompt "Write a short poem about artificial intelligence."

Python API (with Chat Template)

from mlx_lm import load, generate

model, tokenizer = load("SirSahOl/Jev-Style-0.8B-Decision-v3-mlx-16bit")

messages = [
    {"role": "user", "content": "Explain quantum superposition in simple terms."}
]
prompt = tokenizer.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)

response = generate(model, tokenizer, prompt=prompt, verbose=True)
print(response)

Who Should Use This?

General guidance:

• Use 4-bit if you want to run this model alongside IDEs, browsers, and background development tools.
• Use 8-bit if you have 16GB+ unified memory and require superior reasoning and code accuracy.
• Use 16-bit for research, benchmarking, evaluation, or high-end workstation deployments.

LM Studio & Local Inference Setup Guide

To prevent runaway loops and ensure correct conversational turn-taking, configure custom stop tokens in your local inference runtime:

1. <|im_start|>
2. <|im_end|>
3. <|endoftext|>

Prompt Template Formatting

• System Prefix: <|im_start|>system\n
• System Suffix: <|im_end|>\n
• User Prefix: <|im_start|>user\n
• Assistant Suffix: <|im_end|>\n<|im_start|>assistant\n

Conversion Details

Reproduction

To reproduce this conversion:

pip install mlx-lm==0.31.3
python3 -m mlx_lm.convert --hf-path /Users/z4/.cache/huggingface/hub/models--chaoliangUNSW--Jev-Style-0.8B-Decision-v3/snapshots/b023d1f9c7858fbf01504577a3bfc349ea5c7385 --mlx-path output/b023d1f9c7858fbf01504577a3bfc349ea5c7385-mlx-16bit

Limitations & Known Issues

• 4-bit group-wise quantization introduces minor precision loss compared to unquantized weights; for deep mathematical derivations or precision-critical reasoning, test the 8-bit or 16-bit variants.
• High context sequences (>32K tokens) require sufficient unified memory headroom; ensure unified memory is not overcommitted.
• This is a weight-only MLX conversion designed specifically for Apple Silicon GPUs (M1/M2/M3/M4 series).
