# LTX 2.3 3070 Simple Master

## Summary

Best current `LTX 2.3` low-complexity starter for local video work.

This master uses the simple single-pass workflow instead of the more ambitious first-last-frame or character-sheet variants because your `3070` needs a realistic first foothold, not the fanciest graph on paper.

## Status

- `best-current`
- `not-yet-tested-on-chris-box`

## Workflow asset

- `workflow.json`

## Built from

- `models/ltx/ltx23-i2v-t2v-simple-single-pass/`

## Why this is the current master

- Most plausible `LTX` starting point on tighter VRAM
- Simpler graph means less time chasing broken helper nodes
- Supports both `image-to-video` and `text-to-video` style experimentation from one baseline

## What I intentionally kept

- single-pass graph shape
- split-model assumption from the source pack
- lighter starting complexity than the bigger RuneXX graphs

## What I intentionally did not add yet

- first-last-frame complexity
- character-sheet consistency branches
- extra memory-efficiency gadgets unless needed

## Required custom nodes

- `ComfyUI-KJNodes`
- `rgthree-comfy`
- `easy use` / `easy showAnything`
- optional `ComfyUI-GGUF` support remains present in the source graph

## Monday test checklist

- Confirm whether it loads at all on the `3070`.
- Check whether preview/decode settings feel like the real bottleneck.
- If it works, then try the heavier first-last-frame workflow second.

## Next optimization candidates

- strip unused optional loader paths if they create confusion
- create a separate `first-last-frame` master only if the simple master proves viable
