Purpose

Local Apple Silicon wrapper for SulphurAI/Sulphur-2-base video generation model. Uses the MLX LTX runtime (dgrauet/ltx-2-mlx) with optional prompt enhancer. Modeled after the Stable Audio 3 desktop project — adds CLI, installer, and browser GUI without vendoring large model weights.

• Prompt enhancer: MLXBits/sulphur-promptenhancer-mlx-q8 (optional)
• Runtime: dgrauet/ltx-2-mlx
• GUI: Browser UI on 127.0.0.1:8786 via gui.sh
• Install: install.sh -y for env + model setup

Dependencies

• MLX / ltx-2-mlx runtime
• pyproject.toml
