A community developer going by T8 has published a sprawling ComfyUI extension pack for MiniMax H3, the joint audio and video diffusion transformer, with matching nodes and workflows for Alibaba PAI's freshly released 8-step acceleration LoRAs. The project, comfyui-minimax-h3-audio-T8, has cleared 800 stars and registers 54 nodes across seven menus covering conditioning, sampling, long-video chaining, speech, and source-video repainting.
Alibaba PAI just dropped the official MiniMax-H3-Acc-LoRAs, which render joint video and synchronized audio in 8 or 4 sampler steps with no classifier-free guidance. These go beyond ordinary adapters. Alongside a rank-64 trunk LoRA, each checkpoint carries a Parallel Decoding Distillation head bank: 32 per-interval copies of the final-layer video and audio projections that fuse into a single mean-block-velocity head at each sampler step. A plain LoRA loader silently discards the head bank and loses the distillation.
What actually ships in the pack
The T8 extension is not itself a runtime for those PDD files (the reference loader for those is Jalen-Brunson's PDD Acc node). Instead, it wraps the whole MiniMax H3 workflow surface in ComfyUI and includes a Turbo LoRA conversion utility in
