This repository contains a local Apple-Silicon MLX conversion of the gated
Lightricks/LTX-2.5 checkpoint.
It is a derived conversion for MLX; it is not an official Lightricks release.
Review and comply with the original model license and usage policy before
redistributing or using the files.
The Transformer index and Gemma index are included. Conversion manifests record
the source revision, tensor inventory, quantization policy, and completed
shards. No original BF16 Transformer payload is included.
Clone the companion runtime from
vanch007/ltx-2.5-mlx, download this
model repository, and either place the files in the runtime's expected layout
or point the local assembly/generation wrapper at the downloaded directories.
The runtime supports one-stage and two-stage T2AV, repeatable I2V image
anchors, and generated-keyframe conditioning.
These checks do not claim full-pipeline pixel or waveform equivalence with the
official PyTorch implementation. The full 42 GiB BF16 Transformer source sweep
was intentionally skipped; only the converted Q8 artifacts are published.
See the runtime repository's conversion scripts and the pinned source manifest.
The source model is gated and requires Hugging Face access approval. The local
conversion used the LTX-2.5 source revision recorded in each
conversion-manifest.json.
