+# LTX 2.3 Basic for Checkpoint Models
+
+## Summary
+
+`LTX 2.3` basic workflow variant intended for checkpoint-model loading rather than only split-model wiring. Useful if you want a more standard loading path while still staying inside the RuneXX ecosystem.
+
+## Model Family
+
+- `ltx`
+
+## Status
+
+- `imported-only`
+
+## Source
+
+- Workflow pack page: <https://huggingface.co/RuneXX/LTX-2.3-Workflows>

+- Supporting split/checkpoint model page: <https://huggingface.co/Kijai/LTX2.3_comfy>
+- Original publisher: `RuneXX`
+- Date imported: `2026-08-08`
+
+## Developer notes
+
+- RuneXX says the extracted-model path may run easier, but also notes you can swap to default Comfy checkpoint loading if desired.
+- This workflow includes more tuning and helper nodes than the simple single-pass graphs.
+
+## Our notes
+
+- More flexible than the simplest LTX imports, but also more dependency-heavy.
+- On a `3070`, this is more of a “second test” workflow after the single-pass variants.
+- Worth keeping because it may be a better base for later cleanup if the simpler workflows are too stripped down.
+
+## Required custom nodes
+
+- `ComfyUI-KJNodes`
+- `rgthree-comfy`
+- `easy use` / `easy showAnything`
+- optional `ComfyUI-GGUF` hooks are present
+
+## Notes
+
+- Better treated as a richer base graph than as the first low-VRAM test.

+# 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.

+- Original publisher: `RuneXX`
+- Date imported: `2026-08-08`
+
+## 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.

+# LTX 2.3 T2V Simple Single Pass
+
+## Summary
+
+Simpler text-to-video only `LTX 2.3` workflow from the RuneXX pack. Chosen because it avoids some of the extra image-input complexity while still staying in the lower-bloat part of the workflow pack.

+- Original publisher: `RuneXX`
+- Date imported: `2026-08-08`
+
+## Developer notes
+
+- Same general workflow family as the other RuneXX imports, built around the extracted `Kijai` model layout.
+- The pack is designed to support both standard and GGUF-oriented loading choices, depending on what the user has installed.
+
+## Our notes
+
+- This is probably the simplest `LTX 2.3` text-to-video import we currently have.
+- On a `3070`, it is still a “tight to heavy” experiment, but it is a better first look than the more elaborate prompt-relay or long-video graphs.
+- Good candidate for a later optimized low-complexity LTX master if the outputs are decent.
+
+## Required custom nodes
+
+- `ComfyUI-KJNodes`
+- `rgthree-comfy`
+- `easy use` / `easy showAnything`
+
+## Notes
+
+- Best LTX pure T2V starter in the current batch.
