LTX-2.5 serving bundle
A mirror, not a new model. Every weight file here is copied byte-for-byte
(server-side, via huggingface_hub.copy_files) from
Lightricks/LTX-2.5 and is
governed by the LTX-2.x Community License linked above. All credit to
Lightricks.
It exists because RunPod Serverless' model-caching feature allows exactly one
cached repo per endpoint and cannot filter which files it pulls — naming the
upstream repo directly would pre-provision all ~299 GB of it, including
ComfyUI-only int8 variants this deployment never loads. This repo is the
subset ltx-pipelines actually needs, and nothing else.

Deliberately excluded: *-comfy-int8-convrot.safetensors (ComfyUI-only,
ltx-pipelines cannot read them), vae/ltx-2.5-video-vae-conv-bf16 (faster,
lower-quality alternative), latent_upscale_models/*temporal* and
model_patches/ltx-2.5-duration-head-bf16 (auto-duration is unwanted where
billing is per requested duration).
Notes
- Resolution must be divisible by 64 for two-stage pipelines
(
assert_resolution(..., is_two_stage=True)) — the model card's "divisible by 32" is the one-stage rule. - Frame count must satisfy
num_frames % 8 == 1. - LTX-2.3 files are not interchangeable with these, and a LoRA only works with the model it was trained on.
