LTX 2.3 MLX

Purpose

Local Apple Silicon wrapper for Lightricks LTX 2.3 using native MLX weights (dgrauet/ltx-2.3-mlx-q4 default, q8/bf16 optional) rather than the upstream Diffusers/PyTorch checkpoint. Supports text-to-video, image-to-video, and audio-to-video.

Architecture

Follows the local-mlx-wrapper-pattern. install.sh clones/syncs the dgrauet/ltx-2-mlx runtime; ltx23 CLI with --mode t2v|i2v|a2v; stdlib GUI on port 8788 (coexists with Sulphur 8786, Lance 8787). Frame counts follow 8k+1. Conservative distilled defaults (512×320, 49 frames, low-RAM streaming on). ffmpeg required for MP4.

Dependencies

Wrapper carries zero runtime deps; MLX weights (~59.7 GB Q4 HF bundle, ~16 GB practical path) resolved through HuggingFace on first generation.

CI/CD

No CI workflows. install.sh / gui.sh bootstrap.
