# LTX 2.3 INT8 MSR

## Summary

Same-day `LTX 2.3` multiple-subject reference workflow from `javawock7618`. This is the more practical LTX drop if you care about mixing several references into one scene instead of just doing plain text-to-video.

## Model Family

- `ltx`

## Status

- `imported-only`

## Source

- Workflow pack page: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows>
- Workflow file: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows/resolve/main/LTX2.3_int8_MSR-javano2608.1.json?download=true>
- Original publisher: `javawock7618`
- Date imported: `2026-08-11`

## Developer notes

- The source README says this workflow can blend up to 5 inputs, including 1-4 subjects plus a background.
- The pack is built around distilled GGUF and INT8 paths for `lightricks/ltx-2.3`.
- The same pack also calls out an INT8 speedup path, prompt enhancement, and optional voice support in other graphs.

## Our notes

- This is one of the more interesting LTX variants for consistency and scene control.
- On an RTX 3070 / 8 GB setup it is still tight, but it is a real workflow rather than a placeholder.
- Good pick when you want a reference-heavy LTX path instead of a generic one-shot generator.

## Required custom nodes

- `ComfyUI-KJNodes`
- `ComfyUI-LTXVideo`
- the keyframe/director nodes named in the source README if ComfyUI flags them as missing

## Required models

- `lightricks/ltx-2.3` distilled GGUF or INT8 checkpoints
- `ltx-2.3-spatial-upscaler-x2-1.1` for the detailer / upscaler lane

## Notes

- Best LTX import from this batch if you want reference blending and multi-subject handling.
- Expect to trim resolution and keep the graph lean on an 8 GB card.
