Dev builds ComfyUI nodes to add batch generation to MiniMax H3 workflows
an80sPWNstar · reddit · 2026-11-13
A Reddit user with 20 years in IT (not a programmer) used Claude Code to build two custom ComfyUI nodes that fix a pain point in MiniMax H3 image/video workflows: unlike Flux.2 Klein 9b, H3 couldn't increase batch size. The nodes let a single run produce 2+ distinct images or videos, behaving like a true larger batch. The project is MIT-licensed and already on the ComfyUI Registry (comfyui-h3-image-batch). Demo images show batches of 4 dragon/taxi edits and the wiring approach using an Int node.
