🛠 MiniMax H3: Ten New Arrivals in ComfyUI in One Week

The "Neuronaut" digest (part 25) collected 10 tools and LoRAs for MiniMax H3, almost all released between September 13–17. ComfyUI 0.36.0 fixes Fun ControlNet, adds Video Concatenate, and VAE optimizations. ClipProj v3.1 compresses the Qwen3-VL-32B encoder to 26 MB: VRAM drops from 15.7 to 4.5 GB. Also — LoRA face swap, 70s cel-animation, pixel-art, float32 VAE decoding in EXR, and int8-VAE.

🌍 The open MiniMax H3 ecosystem is growing at the pace of an established base model, and the ClipProj + int8-VAE combination lowers the barrier to entry: local video production moves from flagship cards to weaker GPUs.

👤 Almost everything is free: update ComfyUI to 0.36.0, download LoRAs from Hugging Face or Civitai, and run the official Fast H3 workflow. If you have low VRAM, install ClipProj v3.1 and int8-VAE first.
