# 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`
|

## 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.
