+# 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`
+
+## Status
+
+- `imported-only`
+
+## Source
+
+- Workflow pack page: <https://huggingface.co/RuneXX/LTX-2.3-Workflows>
+- Workflow file: <https://huggingface.co/RuneXX/LTX-2.3-Workflows/resolve/main/LTX-2.3_-_I2V_T2V_Simple_single_pass.json?download=true>

+- 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.
