LTX-2.3 Spatial Upscaler x2 1.1 (Diffusers)

Diffusers-format conversion of ltx-2.3-spatial-upscaler-x2-1.1.safetensors from the official Lightricks/LTX-2.3 release.

Weights are byte-identical to the upstream release; only the layout has been rearranged so LTX2LatentUpsamplerModel.from_pretrained and LTX2LatentUpsamplePipeline can consume it directly.

Usage

import torch
from diffusers.pipelines.ltx2 import LTX2LatentUpsamplerModel
from diffusers.pipelines.ltx2.pipeline_ltx2_latent_upsample import LTX2LatentUpsamplePipeline

latent_upsampler = LTX2LatentUpsamplerModel.from_pretrained(
    '<your-username>/<your-repo>',
    subfolder='latent_upsampler',
    torch_dtype=torch.bfloat16,
)
upsample_pipe = LTX2LatentUpsamplePipeline(vae=your_pipe.vae, latent_upsampler=latent_upsampler)
