GLM 4 9B 0414 4bit DWQ

🚀 GLM-4-9B-0414-4bit-DWQ - Optimal DWQ 4-bit Quantized ⚡

This project offers a high - performance 4 - bit DWQ quantization of THUDM/GLM - 4 - 9B - 0414. It is verified through real M4 Max benchmarks and its performance can be predicted for all Apple Silicon chips, providing an efficient solution for text generation tasks.

📦 Installation

Step 1: Environment Setup

# Install MLX and dependencies
pip install mlx-lm transformers torch

# Verify Apple Silicon optimization
python -c "import mlx.core as mx; print(f'MLX device: {mx.default_device()}')"

💻 Usage Examples

Basic Usage

from mlx_lm import load, generate

# Load GLM-4-9B DWQ model
model, tokenizer = load("Narutoouz/GLM-4-9B-0414-4bit-DWQ")

# Generate with optimal settings
response = generate(
    model, 
    tokenizer, 
    prompt="Your prompt here",
    max_tokens=100,
    temperature=0.7
)
print(response)

LM Studio Configuration - IMPORTANT!

# CRITICAL: Unlock 128K context in LM Studio
# 1. Load GLM-4-9B-0414-4bit-DWQ in LM Studio
# 2. Go to Model Settings
# 3. Change Context Length: 4096 → 131072 (128K)
# 4. This unlocks the full 128K context capability

# Without this change, you'll only get 4K context instead of 128K!

📊 Features

Performance Overview

Real - World Performance Data (Verified on M4 Max)

Apple Silicon Performance for GLM - 4 - 9B - 0414 - 4bit - DWQ

Based on verified M4 Max performance and documented scaling factors:

Context Length & LM Studio Configuration

The GLM - 4 - 9B model supports 128K context length, but LM Studio defaults to 4096 tokens. You must manually change it to 131072 to unlock the full long - context capabilities.

LM Studio Setup Instructions:

1. Load GLM - 4 - 9B - 0414 - 4bit - DWQ in LM Studio.
2. Go to Model Settings.
3. Change Context Length from 4096 to 131072 (128K).
4. This unlocks the full 128K context capability!

Performance Highlights

• ✅ M4 Max Verified: 85.23 tok/s real - world performance
• ✅ Memory Efficient: Only ~8GB RAM usage
• ✅ Fast Loading: ~1.5s load time on M4 Max
• ✅ 128K Context: Full long - context support with proper setup

Chip Recommendations for GLM - 4 - 9B

• M4 Max: 🏆 Best Performance (85+ tok/s) - Ideal for production
• M3 Max/M2 Ultra: 🥈 Great Performance (60+ tok/s) - Excellent for development
• M2 Max/M3 Pro: 🥉 Good Performance (45+ tok/s) - Suitable for personal use
