LTX 2.3 Image Base (bf16)

This repository contains a bf16 base image-only checkpoint derived from the base LTX 2.3 model by Lightricks.

It is a pruned image-only execution package: the model is organized for the LTX 2.3 image generation path and does not expose the original video/audio generation flows. The underlying model family and weights remain derived from LTX 2.3, and this package continues to inherit the original LTX Video 2 Open Source License.

What Changed

• Packaged for Diffusers-based image-only inference.
• Pruned to remove components that are not needed by the image execution path.
• Intended for the LTX2ImagePipeline and LTX2ImageImg2ImgPipeline implementations used by the DEVAIEXP image runners.
• Not a new training run and not a dataset modification.

Variant

This variant keeps the base image transformer in bf16 precision.

• Best quality reference among the base image-only variants.
• Recommended when quality and prompt flexibility matter more than memory footprint.
• Uses the base inference setup: more denoising steps than distilled and classifier-free guidance enabled.

Usage

For installation, environment setup, model path expectations, and runnable text-to-image / image-to-image examples, see:

https://github.com/DEVAIEXP/ltx2-image-diffusers

That repository uses a temporary Diffusers branch with the LTX 2.3 image pipelines until equivalent support is available upstream.
