Introduction of ltx2-dev-4bit-mlx

Model Details of ltx2-dev-4bit-mlx

LTX-2 19B Dev (4-bit) - MLX

This is a 4-bit quantized version of the LTX-2 19B Dev model, optimized for Apple Silicon using MLX.

Model Description

LTX-2 is a state-of-the-art video generation model from Lightricks. This version has been quantized to 4-bit precision for efficient inference on Apple Silicon devices with MLX.

Key Features
  • Pipeline : Dev (full control with CFG scale)
  • Quantization : 4-bit precision
  • Framework : MLX (Apple Silicon optimized)
  • Memory : ~19GB VRAM required
Usage
Installation
pip install git+https://github.com/CharafChnioune/mlx-video.git
Command Line
# Basic generation
mlx-video --prompt "A beautiful sunset over the ocean" \
    --model-repo AITRADER/ltx2-dev-4bit-mlx \
    --pipeline dev \
    --height 512 --width 512 \
    --num-frames 33

# Dev pipeline with CFG
mlx-video --prompt 'A cat playing with yarn' \\
    --model-repo AITRADER/ltx2-dev-4bit-mlx \\
    --pipeline dev \\
    --steps 40 --cfg-scale 4.0
