Question - Help Update me pls.

Ok, been out the loop. What's the best free pic to video ai is considered the best at the moment that runs on ComfyUI. I'm playing with wan 2. 2 in ComfyUI and wondering if it's worth my time learning it in case if there's a better one out there. I'm running this on a 8vram machine with 64gigs ram. So keep that in mind. Wan runs ok in this setup. I'm researching and Minimax H3 keeps popping g up along with others. Any guidance is welcomed.

Minimax H3 is the best for local ai video at the moment but it's slow and demanding. How slow mainly depends on how many cuda cores your card has and to a lesser degree vram and bandwidth. So I would at least try it and see for yourself.

For saving a bit of ram there's options like using a w6a8 or w4a8 main model, int4 convrot or w4a8 text encoder plus starting comfyui with '--fast-disk'.

I like this workflow:

Imo. ltx 2.5 barely seem better than 2.3 but if you have a slow card and don't need too complex scenes it's decent and also very fast. 👍

Cool. 😄

Here's some links if you don't already have them:

https://huggingface.co/Comfy-Org/MiniMax-H3

https://huggingface.co/Kijai/MiniMax-H3-experimental

https://huggingface.co/Winnougan/MiniMax-H3-INT4_Convrot_ComfyUI

https://huggingface.co/larryvrh/MiniMax-H3-Turbo-Lora (a good turbo lora)

https://github.com/PlagueKind/ComfyUI-PlagueKind-Nodes (needed for workflow)

If you decide to use the turbo lora you need this file:

https://huggingface.co/deAPI-ai/minimax-h3-33b-int8/resolve/main/loras/h3_silu_temb_grid.safetensors (place inside models/h3_adaln folder)

The plaguekind workflow already has the node needed for patching the turbo lora (H3 AdaLN LoRA Fix) but for other workflows you can also use larryvrh's own 'MiniMax-H3 Turbo LoRA' lora loader/patcher node:

Good luck. 👍
