# LTX 2.3 I2V/T2V Simple Single Pass

## Summary

Community `LTX 2.3` single-pass workflow supporting both image-to-video and text-to-video. Chosen as a lower-complexity starting point for tighter VRAM situations.

## Model Family

- `ltx`

## Developer notes

- RuneXX says the workflows are based on extracted models from `Kijai/LTX2.3_comfy`.
- The repo explicitly says the extracted models may run easier on your computer as separate files.
- The README also recommends keeping `ComfyUI-KJNodes`, `ComfyUI-GGUF`, and ComfyUI itself fully up to date.

## Our notes

- This is one of the better `3070` candidates in the LTX set because it aims for a simpler single-pass route rather than the larger story/multi-scene graphs.
- Still not truly light, but it is more realistic than the giant movie-maker style workflows.
- Good first LTX import when you want to see whether the family is practical at all on your box.

## Required custom nodes

- `ComfyUI-KJNodes`
- `rgthree-comfy`
- `easy use` / `easy showAnything`
- optional `ComfyUI-GGUF` support is present in the graph, though not required if you stay on standard loaders

## Notes

- Best LTX first try for low-complexity local testing.
- If this feels too heavy, the next thing to optimize is usually preview/decode choices and model-loading path.
