ltx 2 3 mlx.stub
id: ltx-2-3-mlx name: LTX 2.3 MLX repo_path: ~/Documents/sw30labs/repos/ltx-2.3-mlx remote_url: https://github.com/sw30labs/ltx-2.3-mlx.git primary_language: Python framework: MLX (ltx-2-mlx runtime wrapper) category: local-inference-mlx stacks: [mlx, cli] ingested: 2026-07-09 last_commit_date: 2026-05-28
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.
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.
Wrapper carries zero runtime deps; MLX weights (~59.7 GB Q4 HF bundle, ~16 GB practical path) resolved through HuggingFace on first generation.
No CI workflows. install.sh / gui.sh bootstrap.
