| # 22th January 2026: Tiny VAE and live previews: |
|
|
| LTX2 Tiny VAE has been trained by [madebyollin](https://github.com/madebyollin), and now has preliminary support in ComfyUI nightly version. |
|
|
| It can be used with normal VAE Loader and encode/decode nodes, but the quality is very low so it's only useful for preview purposes. |
|
|
| Also currently for live animated sampler preview it can be only used with my **LTX2SamplingPreviewOverride** -node in KJNodes, simply load the VAE and plug it in, this overrides any preview setting too. |

| # 13th of January 2026 update !!IMPORTANT!! |
|
|
| Turns out the video VAE in the initial distilled checkpoints has been wrong one all this time, which (of course) was the one I initially extracted. |
| It has now been replaced with the correct one, which should provide much higher detail |
| ## requires using updated KJNodes or new enough core ComfyUI VAELoader to work correctly |

| Separated LTX2 checkpoint for alternative way to load the models in Comfy |
|
|

|
|
|
|
| LTX2 GGUFs that include the metadata also work with the setup, if your GGUF nodes are up to date. |
|
|
| Dev and distill embeddings_connector weights are extracted from their respective original models, they do give quite different results, but it's unclear if there's a "correct" one to use in any given situation. |

| Loras folder includes rank reduced loras that can be useful to reduce the memory requirements. |
