# 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: - Workflow file: - Supporting split/checkpoint model page: - 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.
