# LTX 2.3 INT8 Multi-Subject Reference

## Summary

`LTX 2.3` multi-subject reference workflow with INT8 optimization. This is the one from the `javawock7618` pack that matters most for reference-heavy scene building.

## Model Family

- `ltx`

## Status

- `imported-only`

## Source

- Workflow pack page: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows>

## Developer notes

- Comes from the same-day `javawock7618` LTX 2.3 workflow pack.
- The pack describes this as the `Multiple Subject Reference` path, with up to five input references.
- INT8 is the main reason to keep this one around instead of treating it as a novelty pack.

## Our notes

- This is the strongest new LTX import for character, object, and multi-reference consistency.
- It is probably still heavy on an `RTX 3070 / 8 GB`, but the INT8 path makes it the most practical version of this idea to keep testing.
- Good candidate for later comparison against the repo's simpler LTX character-sheet workflows.

## Required custom nodes

- `ComfyUI-KJNodes`
- `ComfyUI-LTXVideo`
- `keyframeflf` / `flf` helpers used by the pack

## Required models

- `lightricks/ltx-2.3` distilled GGUF or INT8 weights, depending on the local setup

## Notes

- Best same-day LTX workflow for reference and subject-composition work.
